Introduction
This macro library guide supports only the IGLOO, ProASIC3, SmartFusion and Fusion families.
IGLOO indicates IGLOO nano, IGLOO PLUS, IGLOO and IGLOOe families; ProASIC3 indicates ProASIC3 nano,
ProASIC3E, ProASIC3L and ProASIC3 families.
For information on macros available in other familes, see the appropriate Macro Library Guide.
ProASIC3 introduced a new naming convention for sequential macros that is unambiguous and extensible, making it
possible to understand the function of the macros by their name alone.
The first two mandatory characters of the macro name will indicate the basic macro function:
•
DF - D-type flip-flop
•
TF - Toggle flip-flop
•
JF - JK flip-flop
•
DL - D-type latch
The next mandatory character indicates the output polarity:
•
I - output inverted (QN with bubble)
•
N - output non-inverted (Q without bubble)
The next mandatory number indicates the polarity of the clock or gate:
•
1 - rising edge triggered flip-flop or transparent high latch (non-bubbled)
•
0 - falling edge triggered flip-flop or transparent low latch (bubbled)
The next two optional characters indicate the polarity of the Enable pin, if present:
•
E0 - active low enable (bubbled)
•
E1 - active high enable (non-bubbled)
The next two optional characters indicate the polarity of the asynchronous Preset pin, if present:
•
P0 - active low preset (bubbled)
•
P1 - active high preset (non-bubbled)
The next two optional characters indicate the polarity of the asynchronous Clear pin, if present:
•
C0 - active low preset (bubbled)
•
C1 - active high preset (non-bubbled)
Combinatorial macros all use one tile in the SmartFusion, Fusion and ProASIC3 families.

There are two RAM macros in the ProASIC3/ProASIC3E library: RAM4K9 and RAM512X18. The RAM4K9 is a fully synchronous, true
dual-port RAM with an optional pipeline stage. It can be used for word widths up to 9 bits. Both ports are capable of reading and writing,
making it possible to write with both ports or read with both ports simultaneously. You can also read from one port while writing to the
other. Each port also has an optional pipeline stage that can be controlled separately via the PIPE pins. The RAM512X18 is a fully
synchronous, two-port RAM with an optional pipeline stage. You can use it for word widths of 9 or 18 bits. It has one dedicated read
port and one dedicated write port (you can read from one port while writing to the other). The read port also has an optional pipeline
stage that you can control separately via the PIPE pin.
During the write operation of the RAM4K9, the WMODE pins control the data that appears on the read pins of the same port. When
WMODE is high, the same data appears on the read and write ports at the rising CLK edge. When WMODE is low, the old data stored
in the current memory location being addressed appears on the read port. There are no WMODE pins on the RAM512X18.
The aspect ratio of each port can be specified independently via the WIDTHA and WIDTHB pins. For the RAM512X18, the allowable
values are 18 x 256 and 9 x 512. For the RAM4K9, the allowable values are 9 x 512, 4 x 1K, 2 x 2K, and 1 x 4K. Although it is possible
to dynamically reconfigure the aspect ratios, the RAM was designed with only static configuration in mind, so the timing is unknown
and you are discouraged from performing such operations. The same is true for the WMODE and PIPE configuration pins.
The RAM4K9 only needs 2 bits to configure the WIDTH. The allowable RAM4K9 WIDTHA and WIDTHB values are shown in the table
below.

The RAM512X18 also needs 2 bits to configure the read and write widths. The allowable RAM512X18 WW and RW values are shown
in the table below.

When specifying a width that is less than the maximum (e.g. 1), the upper unused data input pins (e.g. DINA8 - DINA1) must be
connected to GND. When specifying a depth that is less than the maximum (e.g. 512), the upper unused address pins (e.g. ADDRA11
- ADDRA9) must also be connected to GND.
When widths of 1, 2, and 4 are used, the ninth bit is skipped. This can cause counter-intuitive effects when these widths are used for
read operations and larger widths are used for write operations (or vice versa). For example, if a width of 9 is used for writing and a
width of 1 for reading, every 9th bit will be dropped. This effect may be desirable for removing parity bits. If a write width of 4 and read
width of 9 is used, the 9th bit may either contain garbage or remnants of previous write operations when a write width of 9 or higher was
being used. For this reason, SmartGen only supports the following aspect ratio combinations when one of the ports is configured with a
1-, 2-, or 4-bit width using the RAM4K9.

The RAM4K9 can still be used for 9-bit width applications, but no other bit-width can be used with it other than 9-bits.

There are several restrictions that apply when you use an 18 x 256 aspect ratio. For this reason, SmartGen uses the RAM512X18
whenever 18-bit widths are specified. The only allowable combinations of read and write configurations for the RAM512X18 are as
follows:
RAM512X18 Read and Write Combinations
READ
WRITE
18 x 256
18 x 256
18 x 256
9 x 512
9 x 512
18 x 256
The RADDR pins are always used for the read address in the above configurations and the WADDR pins are used for the write
address. The RW pin is used to specify the read width and the WW pin for the write width. The WD pins are used for writing data and
the RD pins for reading data.

When deserted, the BLK pins will cause the DO outputs to hold their last value. When asserted, the WEN pins can be used to switch
each port between write and read mode. The RESET pin sets all outputs low but does not reset the memory. The WMODE pins are
used to either allow the write data to appear immediately on the output pins or to hold the last value.

Use SmartGen to configure the RAM for typical use. SmartGen will not support dynamic reconfiguration or cascading width-wise.
Customers who wish to use such features must instantiate and configure the RAM macro manually. You can configure your RAM
dynamically if you use the FlexRAM macros in the next section.
Warnings
•
Simultaneous write and read to same address is detected and if timing requirements are not met, read data is driven to X.
Write operation is not affected.
•
Simultaneous write to the same address from both ports is possible, but the results are undefined. Avoid writing to the same
address simultaneously from both ports.
•
Dynamic reconfiguration of any pins possible but not supported by SmartGen.
•
Cascading is possible and limited only by the number of available RAM blocks in a row, which is device dependent.
SmartGen prompts you for device type information in order to correctly calculate the maximum.
•
RESET has priority over BLKA and BLKB.
•
In read mode (i.e. when WEN high) WMODE is ignored.

There are two dynamically reconfigurable RAM macros in the Fusion library: FLEXRAM4K9 and FLEXRAM512X18. The
FLEXRAM4K9 is a fully synchronous, true dual-port RAM with an optional pipeline stage. It can be used for word widths up to 9 bits.
Both ports are capable of reading and writing, making it possible to write with both ports or read with both ports simultaneously. You can
also read from one port while writing to the other. Each port also has an optional pipeline stage that can be controlled separately via the
PIPE pins. The FLEXRAM512X18 is a fully synchronous, two-port RAM with an optional pipeline stage. You can use it for word widths
of 9 or 18 bits. It has one dedicated read port and one dedicated write port (you can read from one port while writing to the other). The
read port also has an optional pipeline stage that you can control separately via the PIPE pin.
During the write operation of the FLEXRAM4K9, the WMODE pins control the data that appears on the read pins of the same port.
When WMODE is high, the same data appears on the read and write ports at the rising CLK edge. When WMODE is low, the old data
stored in the current memory location being addressed appears on the read port. There are no WMODE pins on the
FLEXRAM512X18.
The aspect ratio of each port can be specified independently via the WIDTHA and WIDTHB pins. For the FLEXRAM512X18, the
allowable values are 18 x 256 and 9 x 512. For the FLEXRAM4K9, the allowable values are 9 x 512, 4 x 1K, 2 x 2K, and 1 x 4K. Actel
recommends that you do not change the WMODE and pipe configuration pins dynamically because the timing is unknown.
The FLEXRAM4K9 only needs 2 bits to configure the WIDTH. The allowable FLEXRAM4K9 WIDTHA and WIDTHB values are shown
in the table below.

When specifying a width that is less than the maximum (e.g. 1), the upper unused data input pins (e.g. DINA8 - DINA1) must be
connected to GND. When specifying a depth that is less than the maximum (e.g. 512), the lower unused address pins (e.g. ADDRA2 ADDRA0) must also be connected to GND.
When widths of 1, 2, and 4 are used, the ninth bit is skipped. This can cause counter-intuitive effects when these widths are used for
read operations and larger widths are used for write operations (or vice versa). For example, if a width of 9 is used for writing and a
width of 1 for reading, every 9th bit will be dropped. This effect may be desirable for removing parity bits. If a write width of 4 and read
width of 9 is used, the 9th bit may either contain garbage or remnants of previous write operations when a write width of 9 or higher
was being used. For this reason, Actel recommends that you use only the following aspect ratio combinations when one of the ports is
configured with a 1-, 2-, or 4-bit width using the FLEXRAM4K9.

There are several restrictions that apply when you use an 18 x 256 aspect ratio. For this reason, Actel recommends that you use the
FLEXRAM512X18 whenever 18-bit widths are specified. The only allowable combinations of read and write configurations for the
FLEXRAM512X18 are as follows:
FLEXRAM512X18 Read and Write Combinations

The RADDR pins are always used for the read address in the above configurations and the WADDR pins are used for the write
address. The RW pin is used to specify the read width and the WW pin for the write width. The WD pins are used for writing data and
the RD pins for reading data.

FIFO4K18 is fully synchronous and has its own built-in controller. Like the RAM, the FIFO can have different write and read aspect
ratios that can be configured dynamically. The WW and RW pins are used to specify one of five allowable aspect ratios, as shown

The AEVAL and AFVAL pins are used to specify the almost empty and almost full threshold values, respectively. In order to handle
different read and write aspect ratios, the values specified by the AEVAL and AFVAL pins are to be interpreted as the address of the
last word stored in the FIFO. The FIFO actually contains separate write address (WADDR) and read address (RADDR) counters.
These counters calculate the 12-bit memory address that is a function of WW and RW, respectively. WADDR is incremented every time
a write operation is performed and RADDR is incremented every time a read operation is performed. Whenever the difference between
WADDR and RADDR is greater than or equal to AFVAL, the AFULL output is raised. Likewise, whenever the difference between
WADDR and RADDR is less than or equal to AEVAL, the AEMPTY output is raised. Therefore AEVAL and AFVAL must be left-justified
for widths greater than one (i.e. unused lsb’s must be grounded).

When the number of words stored in the FIFO reaches the amount specified by AEVAL while reading, the AEMPTY output will go high.
Likewise when the number of words stored in the FIFO reaches the amount specified by AFVAL while writing, the AFULL output will go
high. The FULL and EMPTY outputs will go high when the FIFO is completely full or empty, respectively.
It should be noted that the internal memory size is 512 X 9. When widths of 1, 2, and 4 are specified, the 9th bit is skipped.
The ESTOP pin is used to stop the read counter from counting any further once the FIFO is empty (i.e. the EMPTY flag goes high).
Likewise, the FSTOP pin is used to stop the write counter from counting any further once the FIFO is full (i.e. the FULL flag goes high).
These are configuration pins that should not be dynamically reconfigured. SmartGen treats them as static configuration pins and
always ties them high.
Independent read and write operations are allowed, however only the read port can be pipelined. Data on the appropriate WD pins are
written to the FIFO every rising WCLK edge as long as WEN and WBLK are low. Data is read from the FIFO and output on the
appropriate RD pins every rising RCLK edge as long as REN is high and RBLK is low.
The active low RESET pin is used to asynchronously clear the outputs of the FIFO and reset the internal read and write address
counters. It sets all the RD pins low, the FULL and AFULL pins low, and the EMPTY and AEMPTY pins high, however the contents of
the memory remain unchanged. RESET has priority over RBLK and WBLK.
When instantiating the FIFO4K18, all unused input pins must be connected to GND.
Warnings
•
The WW, RW, AEVAL, and AFVAL pins can be dynamically configured, but only static configuration will be supported by
SmartGen.
•
The RPIPE signal can be dynamically configured, but only static configuration will be supported by SmartGen.
•
No pipeline on the write port.
•
Cascading allowed and supported in the width direction only by SmartGen. Cascading in the depth direction requires the use
of a soft controller (i.e. implemented with core logic).
•
ESTOP and FSTOP applications not clear. The effect of activating ESTOP is to allow the read pointer to wrap around,
allowing the memory contents to be read over and over again with rewriting after EMPTY. The effect of activating FSTOP is
not clear, however, since the write pointer could wrap around allowing overwriting of data which is never read. Therefore
SmartGen will always tie these pins off high.

Inputs / Outputs
See the description below for an explanation of the inputs
and outputs available on the Flash memory block macro.
Each Flash Memory block holds 256 kb of data. Although it is functionally similar to a large single-port
synchronous RAM, it has several significant differences, including:
1.
Address bits are MSB justified, unlike RAM4K9 and RAM512X18 in which the address bits are LSB
justified.
2. Write operation updates write data into the block buffer ONLY. To store data permanently into the
Flash Memory Block array writes to a page must be followed by a program operation of the same
page.
3. The simulation models always execute copy page from Flash memory block array (internal operation) in 65 clock cycles; in silicon the behavior is non-deterministic (63-67 clock cycles). This mismatch is reflected in the number of cycles BUSY is asserted.
Operations on Flash memory block are synchronous to rising-edge of CLK.
Flash Memory Block Pin Description
All Flash memory block signals are active high, except for RESET which is active low. The Flash memory
block is a completely synchronous model sensitive to rising edge of CLK input.

Functional Description
The Fusion datasheet, available here, http://www.actel.com/techdocs/ds/default.aspx, contains a
detailed functional description of the entire Flash Memory Block.
Simulation Details for Flash Memory Block
The Flash memory block array can be pre-loaded with user-defined data. For simulation purposes, you
can specify a memory initialization file by over-riding the parameter "MEMORYFILE" in the Verilog netlist
and the generic "MEMORYFILE" in Vital netlist.
118
The memory array declared in simulation models stores data that is one block wide. It is 64k x 140 bits.
The addressing scheme for accessing this array consists of 16 bits, as shown in the figure below.

Addressing Scheme for Accessing the Flash Memory Block Memory Array
ADDR[17:0] is the Flash memory block interface address, SPAREPAGE and AUXBLOCK are input
signals.
The memory file for pre-loading an Flash memory block array consists of "strings of address and data in
hexadecimal notation with address delimiters (@)" and MUST conform to the rules shown below:
1.
Each line MUST contain a string of fixed length (=35 characters) and start with an "@" if it corresponds to an address.
2. Each line following the address line corresponds to a block of data starting at the block address
specified in the address line. This applies until the next line with an address specifier (@) is encountered.
3. Each data block consists of 35 hex chars. Hex[31:0] are the data characters corresponding to 16
bytes of user data with Hex[1:0] corresponding to Byte0 and Hex[31:30] corresponding to Byte15.
Hex[34:32] are ECC related bits and must be addressed manually.
Based on these rules, the format looks like:
@Block_Address_0
Block_Data_0 ( required )
Block_Data_1 ( optional )
Block_Data_2 ( optional )
...
...
Block_Data_8 ( Aux block data for this page, optional )
@Block_Address_n
Block_Data_n
( required )
Block_Data_n+1 ( optional )
Block_Data_n+2 ( optional )
...
...
...
Block_Data_n+8 ( Aux block data for this page, optional )
A typical memory file looks like:
@000…0000 // beginning with @, start address in hex. format. 0s to be padded
// between @ and hex address, to get a string of length 35.
Macro Library Guide
119
ab101fd01… // 35 hexadecimal characters corresponding to each block of Flash memory block cell
eab9c4……
@000…4030 // start address for next data stream
c805489e…. // 35 hexadecimal characters corresponding to each block of Flash memory block cell
96986391…
User Controlled Generics
FAST_SIM - The generic/parameter FAST_SIM is included in pre-synthesis and pre-layout simulation
models to reduce cycles wasted in executing the PROGRAM operation. The default is '1', which means
the PROGRAM operation is executed with a 4 s simulated delay. You can chose to deactivate the
operation by overriding FAST_SIM to 0, in which case PROGRAM is executed with a delay close to real
time of 8.4 ms. You can also choose this mode for post-layout simulations.
WR_THR - When the number of writes to a page in the Flash memory block array (program operation)
exceeds the write threshold specified in the data sheet, the status returned is non-zero. Since the
threshold is a huge value, WR_THR is provided to simulate this failure at a reduced number of writes.
You can override the generic with any non-zero count (such as 10 or 12). The write threshold exceeded
condition is produced on the 10th write to the same page in the Flash memory block array.
Note: The string assigned to the generic/parameter MEMORYFILE is preserved through synthesis and
place-and-route. But for FAST_SIM and WR_THR generics/parameters, you must reassign the desired
value each time after synthesis and place-and-route.

Functional Description
The Fusion datasheet, available at http://www.actel.com/techdocs/ds/default.aspx, contains a detailed
functional description of the entire Analog System Builder.
Connecting Analog Ports
Each analog port must be connected to one of the following “virtual pads”: INBUF_A. INBUF_DA or
OUTBUF_A. AV0, AC0, AT0, …, AV9, AC9 and AT9 are analog inputs that can be used either as analog
or digital inputs. When used as an analog input, the analog input signal (e.g. AV0) must be connected to
an INBUF_A, and the corresponding digital input enable (e.g. DENAV0) must be tied to 0.
When used as a digital input, the analog input must be connected to an INBUF_DA, and the
corresponding digital input enable must be tied to 1.
All other analog inputs (ATRETURN01, ATRETURN23, ATRETURN45, ATRETURN67, and
ATRETURN89) must be connected to an INBUF_A.
Note: ATRETURN01, ATRETURN23, ATRETURN45, ATRETURN67, and ATRETURN89 must be
connected to an INBUF_A, even though they have no function in the simulation model.
Analog outputs (AG0, …, AG9) must be connected to an OUTBUF_A instance.
VAREF is an inout pad and does not need to be connected to INBUF_A or OUTBUF_A.
Serialization
The analog ports are represented by a 1-bit wide port in both the Verilog and VHDL simulation models.
Verilog modules and VHDL functions were developed to drive a real value through a 1-bit port and to
read an analog value from a 1-bit port. The Analog System Builder macro contains embedded read and
drive logic to read from the analog input and drive the analog output, respectively.
124
The drive module/function converts a real value into a 64-bit value, serializes it and streams it in zero
simulation time, using delta delays. The read module/function deserializes a 64-bit stream into a 64-bit
value and converts it into a real value.
Connecting Analog Ports with Verilog
Two Verilog modules (drive_analog_io and read_analog_io) are available to drive an analog input and
read an analog output. You must instantiate a drive_analog_io for each analog input and a
read_analog_io for each analog output. The read_analog_io starts as soon as there is a non 'Z' data bit
on the module input pin. All read and drive operations happen in zero time (delta delays).
drive_analog_input is a new module with the same functionality as drive_analog_io and can be used
interchangeably to drive analog inputs.
Example: drive_analog_io with an INBUF_A and OUTBUF_A instantiation

);
OUTBUF_A outbuf_AG0 ( .PAD(AG0_pad), . D (AG0_d) );
initial
begin
AV0_real <= 1.28;
end
Connecting Analog Ports with VHDL
Similarly, two VHDL functions (drive_analog_input and read_analog_input) are available to drive an
analog input and read an analog output. These functions are part of the analog_io VHDL package. The
read_analog_input starts as soon as there is a non 'Z' data bit on the function input pin. All read and drive
operations happen in zero time (delta delays).

drive_temperature_quad and drive_current_monitor
In addition to the standard Verilog drive_analog_io modules and VHDL drive_analog_input procedures
used to drive the analog quads, two Verilog modules and VHDL procedures are also available to drive
the AC and AT quads.
The first Verilog module / VHDL procedure, drive_temperature_quad, takes a temperature in Celsius,
converts it into a voltage, and drives it over the digital input. This can be used regardless of which input is
selected by the Analog MUX - T-prescaler, temperature monitor or T-direct analog input. The equation is:
AT(V) = (Temperature(C) + 273.15 ) * ( 2.30258 * 0.000087248)
The second Verilog module / VHDL procedure, drive_current_monitor, can only be used when driving an
AC quad that will be used for Current Monitoring. As an input it takes the corresponding AV quad voltage
(e.g. AV3's voltage, if driving AC3), the Resistor (in Ohm) and Current (in A) values, to calculate the
voltage on the AC quad (see the Fusion datasheet for more information). The resistor must be between
the 0.01 and 10 Ohm, and (AV - AC) has to be less than 250 mV. The equation is:
AC(V) = AV(V) - (Resistor(Ohm) * Current(A) )
If the analog MUX selects the C-prescaler or the C-direct input, then use the standard VHDL procedure
drive_analog_input or Verilog drive_analog_io modules to drive the AC quad.

drive_current_inputs
This module/procedure has been added to both Verilog and VHDL libraries to drive both the pads of an
AV/AC pair when configured as a current monitor. Voltage for AV, resistor and current are the inputs,
serialized AV and AC are the outputs. You can use this module/procedure to replace a pair of
drive_analog_input and drive_current_monitor instances, as shown in the example below.
drive_current_inputs Verilog Example
Two drivers for driving inputs to voltage and current pads:
drive_analog_io drive_AV0 ( $realtobits(voltage0), AV0_i );
drive_current_monitor drive_CM_AC0 ( $realtobits(voltage0), $realtobits(resistor0),
$realtobits(current0), AC0_i );
drive_current_inputs can drive inputs to both AV and AC pads. For example:
drive_current_inputs drive_AV0_AC0 ( $realtobits(voltage0), $realtobits(resistor0),
$realtobits(current0), AV0_i, AC0_i );
128
drive_current_inputs VHDL Example
Two drivers for driving inputs to voltage and current pads:
drive_analog_io( voltage0, voltage0_pad );
drive_current_monitor ( voltage0, resistor0, current0, current0_pad );
drive_current_inputs can drive inputs to both AV and AC pads. For example:
drive_current_inputs ( voltage0, resistor0, current0, voltage0_pad, current0_pad );
drive_differential_inputs
This module/procedure has been added to both Verilog and VHDL libraries to drive both the pads of an
AV/AC pair when configured for differential inputs. Voltage for AV, AV-AC delta are the inputs, serialized
AV and AC are the outputs.
drive_varef_out
Use this module to drive external VAREF onto VAREF inout pin. Since the applied voltage is serialized,
you must ensure that the receiving logic in AB model is ready to receive the serial stream. Actel
recommends that you wait until the RESET signal is deasserted (inactive) before assigning the external
voltage to VAREF. This module is available in Verilog only. Use drive_analog_input in VHDL to drive
external VAREF.
For example, driving VAREF externally by instantiating drive_varef_out module/procedure:
drive_varef_out Verilog Example
drive_varef_out
i_VAREF (
.parallel_in($realtobits(val_varef)),
.en_out(!SYS_RESET),
.serial_out(VAREF)

Each of the AV, AC, and AT pins may be independently configured to be used as a digital input. An AV/
AC pair refers to the AV and AC associated with a specific quad. When used as a pair these inputs will
both be driven from one function/module. For example:
• AV0 and AC0 can both be driven using drive_current_monitor
• AV9 and AC9 can both be driven using drive_differential_voltage
Note: Make sure that the Flash Memory System Builder's INIT_DONE output is '1' before you drive the
analog block (AB) analog quads (AV0-9, AC0-9 and AT0-9) in the stimulus file. For example:
130
ENTITY testbench IS
END testbench;
Architecture stimuli of testbench is
...
begin
...
drive_analog_input ( real(AV0_real), AV0_serial );
...
serial_AV0 : process
begin
wait until ( INIT_DONE = '1' );
AV0_real <= 1.2;
…
…
end process serial_AV0;
Polarity
Each quad has a polarity bit, Bx[6], (e.g. B0[6] for AV0-polarity and B4[6] for AV1-polarity). The default
polarity is Positive, Bx[6] = '0'. Polarity error occurs when the polarity bit is inconsistent with the quad sign
(e.g. AV0 > 0 and AV0-polarity = '1').
AT-quad can only be positive and therefore its polarity can only be set to Positive, Bx[6] = '0'. For ATquad, polarity error occurs if AT is negative or if AT-polarity is set to Negative, Bx[6] = '1'.
Prescaler
Each quad has a Prescaler Opamp mode bit, Bx[7], (e.g. B0[7] for AV0- prescaler op-amp and B4[7] for
AV1 prescaler op-amp). Default is Powerdown, Bx[7] = '0'.
If the factor of the prescaler input and scaling factor is greater than the internal reference voltage, the
prescaler output will saturate and the prescaler output will be equal to the internal reference voltage
(default 2.56V).
If a Polarity error occurs (e.g. AV0 > 0 and AV0-polarity = '1'), the prescaler output will be '0.0'.
Current Monitor
Each C-quad has a Current Monitor Switch bit (B0[4] for AC0, B4[4] for AC1, etc.). This switch needs to
be 'ON' if the analog MUX selects the Current Monitor, otherwise the analog MUX output will be '0.0'.
Default is Off, B0[4] = '0'.
The current monitor output is the difference between the AV and AC multiplied by a factor of 10. CMSTB9 enables the current monitor for analog quads 0-9. Additionally, each C-quad has a Current-Monitor
Switch (B0[4]) which enables you to switch the current monitor on or off. This switch needs to be 'ON' if
the analog MUX selects the Current Monitor input, otherwise the analog MUX output will be '0.0'. The
default setting is off.
The following requirements must be met in order to use the current monitor:
• ABS(AV) needs to be greater than ABS(AC), otherwise the Current Monitor returns a value of 0.0
• AV and AC must have the same sign and polarity. If not, they are invalid Current monitor inputs, and
the current monitor output will be 0.0
• If a Polarity error occurs (e.g. AV0 > 0 and AV0-polarity = '1', or AC0 < 0 and AC0-polarity = '0'), the
current monitor output will be 0.0
• If the difference between the AV and AC multiplied by a factor of 10 is greater than the internal
reference voltage, the current monitor output saturates and the current monitor output is equal to the
Macro Library Guide
131
internal reference voltage (default 2.56V).
Temperature Monitor
The temperature monitor output is the AT-quad value multiplied by a factor of 12.5. TMSTB0-9 enables
the temperature monitor for analog quads 0-9.
AT quad only accepts positive voltages, and T-pad polarity has to be set to 0 (Positive)
If the AT-quad value multiplied by 12.5 is greater than the internal reference voltage, the temperature
monitor output saturates and the temperature monitor output is equal to the internal reference voltage
(default 2.56V).
When using the temperature monitor, to reflect a temperature change, the value applied to AT should be
a differential voltage.
AT (delta V) = T (K) * (0.0595 / 300)
AT (delta V) = T (K) * 1.983E-4
Using ADC in the Temperature Monitor
Using the previous equation, 300K (room temperature) should correspond to 59.5mV (0.0595 on AT,
therefore 0.748 at the temperature monitor output / ADC input). When doing a 10-bit ADC conversion
using a 2.56V reference voltage, 0.0595 on AT (T=300K) will give a RESULT of 300 (decimal). In this
case, 1LSB change on RESULT corresponds to 1K temperature change.
Direct Analog Input
Each V, C and T-quad has a Direct Analog Input Switch (B0[5] for AV0, B1[5] for AC0, and B3[5] for AT0)
which enables you to switch the direct analog input ON or OFF. This switch must be ON if the analog
MUX selects the direct analog input, otherwise the analog MUX output will be 0.0. The default setting is
OFF.
Analog Quad Switch Conditions
For the V-quad, the analog MUX can choose the V-prescaler or the V-direct analog input; for the Cquads, the analog MUX can select the C-prescaler, C-direct analog input or current monitor; for the Tquads, the analog MUX can choose the T-prescaler, the T-direct analog input or the Temperature
Monitor.
Set the V, C and T-prescaler Opamp, V, C and T-direct analog input switches and Current Monitor switch
need be set according to the table below for power efficiency and/or ADC conversion accuracy.

If you do not meet the switch conditions above, the analog MUX output is 0.0 and an error message
appears.
In addition, when you the AV direct analog input, the scaling factor for the V-prescaler (B0[2-0]) must be
000 to avoid accidental damage if high voltages are applied.
The same restriction applies when you select the AC direct input; the scaling factor for the C-prescaler
(B1[2-0]) must be 000. This restriction does not apply to the AT direct analog input.
When you do not use an analog input quad as an analog input or a digital input, it must tied to GND (1’b0
in Verilog and ‘0’ in VHDL). The corresponding configuration byte must be set to “00000000”.
ADC
The Fusion datasheet, available at http://www.actel.com/techdocs/ds/default.aspx, contains a detailed
description of the ADC.
The power-up calibration time after ADC comes out of reset is 3840 ADC_CLK cycles.
The conversion time can vary greatly depending on the SYSCLK frequency, ADCCLK frequency
(determined by TVC), the STC settings, and the conversion bit-resolution (MODE).
t_conv = t_sync_read + t_sample + t_distrib + t_post_cal + t_sync_write
t_conv = SYSCLK period + ((2 + STC) * ADCCLK period) + (8, 10 or 12 * ADCCLK period) + (2 *
ADCCLK period) + SYSCLK period
t_sync_read: Time for latching the input data
t_sample: Time for sampling the analog signal
t_distrib: Time for charge distribution
t_post_cal: Time for post-calibration
t_sync_write: Time for latching the output data
A Verilog parameter / VHDL generic enables faster conversion time. See the “User Parameter /
Generics” on page 134 for more information.
RTC
When you use the RTC, you must first write the CTRL_STAT register. Refer to the Fusion datasheet for
more information on the functionality of each CTRL_STAT register’s bit. If do not use the RTC, Actel
recommends that you write the CTRL_STAT register to “00000000”.
When doing a byte-read from the counter, the match register, or the individual match bits, byte 0 must be
read before other bytes can be read. A byte 0 read latches the 5-byte register into a 40-bit capture
register. The following read operations are made from the 40-bit capture register. For the counter, the
match register or the individual match bits, if bytes 1 through 4 are read before byte 0 is read, the read
data (ACMRDATA) is irrelevant.

Register Read and Write Conditions
Use ACMADDR, ACWEN and ACMCLK (and ACMWDATA for write) to control RTC read and write
operations. Besides setting those control signals properly, the following conditions need to be met before
the read or write on the chosen register byte can be executed.
COUNTER write: rstb_cnt = '1', cntr_en = '0' and rtm_rst = '0'
MATCHREG write: rtm_rst = '0'
MATCHBITS can not be overwritten
COUNTER read: rstb_cnt = '1' and rtm_rst = '0'
MATCHREG read: rtm_rst = '0'
MATCHBITS read: rstb_cnt = '1' and rtm_rst = '0'
User Parameter / Generics
MEMORYFILE
This feature enables loading of the memory initial values. This can especially help with the AQ-ACM and
RTC configurations. In Verilog the MEMORY is defined as an array of 8 bits by 90, and the memory init
file format needs to be of a similar type. In VHDL, the MEMORY is defined as a 720-bit vector, and the
memory init file needs to be of a similar type. Default is an empty string (i.e. no memory init file).
WARNING_MSGS_ON
This feature enables you to disable the warning messages display. Default is ON ('True' in VHDL and '1'
in Verilog).
FAST_ADC_CONV_SIM
Setting FAST_ADC_CONV_SIM to True enables much faster ADC conversion time; In this fast
simulation mode, the time for latching input and output data (one SYSCLK period each), and the time for
sampling the analog input signal ((2 + STC) * ADCCLK period) are not accounted for. The default is OFF
('False' in VHDL and '0' in Verilog). Set FAST_ADC_CONV_SIM to 'True' in VHDL and to '1' in Verilog to
enable this fast simulation mode.
Note: This is in simulation mode only. There is no equivalent mode on silicon.

Voltage Regulator and Power Supply Monitor
Voltage Regulator and Power Supply Monitor (VRPSM)
Fusion
Function
The Voltage Regulator and Power Supply Monitor were combined into one
macro because the VR and power supply logic work together to control the
power-up state of the FPGA core.
PUB
FPGAGOOD
VRPU
VRINITSTATE
PUCORE
RTCPSMMATCH
Inputs / Outputs
Inputs are listed on the left, outputs on the right.
See the VRPSM signal description below for an explanation of the inputs and outputs.
The VR generates a 1.5 V power supply (500 mA max) from the 3.3 V power supply. The 1.5 V output is
intended to supply all 1.5 V needs of the Fusion product. This regulator requires an external bipolar pass
transistor. Enable for this block is generated in the VR logic block, or from an external pad.
The 1.5 V is not supplied internally to the Fusion device. It must be routed externally to the VCC pins on
the device. Therefore the user is not required to use the V-Reg and can use an off-chip 1.5 V supply if
desired.
The VRPSM can be enabled from several sources: the PUB pin, RTCMATCH signal from the Analog
Block's RTC, or triggered by the PUP0 (RTINIT1 and RTINIT1, PC bits). In the simulation library, PUP0 is
represented by VRINITSTATE. VRINITSTATE is FPGAGOOD initial power-up value. It enables you to
drive FPGAGOOD to '1' or '0', before the 3.3V is up. The PUCORE output is the Power-Up Bar (PUB)
input inverted.
Once triggered the VRPSM remains on because of the latching functions of RS flip-flops. Only the FPGA
fabric can reset these flip-flops and turn off the VRPSM. Once the FPGAGOOD signal is established, this
VRPSM enable mechanism is no longer active. See the tables below for signal descriptions and
recommended power-up sequences.
VRPSM Signal Description and Power-Up Sequences
The signals for the VPRSM macro are listed in the table below. The PUB input comes from the PUB pin
on the device and can be pulled high by a signal external to the Fusion device. This can be used to wake
up from a standby condition. The inputs VRINITSTATE and RTCPSMMTACH come from the VR Init and
RTC blocks respectively and either can initiate a VR power up.

OADIVRST may only be used when you bypass the PLL core (i.e. OAMUX = 001).
The purpose of the O(A/B/C)DIVRDST signals is to reset the output of the final clock divider in order to
synchronize it with the input to that divider when the PLL is bypassed. The signal is active on a low to
high transition. The signal must be low for at least one divider input clock frequency, and then shifted high
for at least 3 input clock cycles for the reset operation to work correctly.

External Feedback for PLL and DYNCCC
External feedback is implemented by relying on self-synchronization in-out on GLA. Since GLA is in the
PLL loop, it automatically synchronizes to the incoming clock, and the additional synchronization circuits
on divider U are disabled when external feedback is enabled.
GLB and GLC still have to rely on synchronization circuits for dividers V and W. As a result, GLA, GLB,
and GLC are synchronized when LOCK goes high.
External feedback comes with the following restrictions:
•
Only GLA (the primary global) may be used as the signal for the external feedback loop.
•
Division factor N is defined as: N = U*a where a= 1, 2, 3, ...
•
Division factor M is defined as: M >= 5
•
Total sum of delays in the feedback loop must be less than 1 VCO period and less than 1 CLKA
(incoming clock) period. This restriction only applies to cases where V and or W dividers are used.
•
M*U < 233
EXTFB must come from an I/O. This I/O is placed at one fixed location per CCC. Please refer to the
Fusion datasheet, IGLOO datasheet, or ProASIC3 datasheet for more information.
External feedback is supported on both PLL and DYNCCC cells for IGLOO, ProASIC3, SmartFusion and
Fusion families.

The UFROM is the USER FlashROM macro. It is a simple 128 X 8 synchronous read-only memory. There is only one UFROM per chip. New
data appears on the DO pins after the falling edge of the clock pin. The
UFROM can only be programmed by the user via the JTAG pins. There
is currently no support for programming the UFROM in any of the CAE
tools or libraries, however the simulation models will utilize a memory
initialization file so users can specify the contents of the memory for
simulation purposes. The memory initialization file will be an ASCII format text file containing exactly 128 lines of 8-character binary strings.
