With an average gate density of 5500 gates/mm2, the CB35000 family allows the design of highly complex devices. The potential available gate count ranges above 1.5 Million equivalent gates. Devices can operate over a Vdd voltage range of 2.7 to 3.6 volts. The I/O count for this array family ranges to over 600 signals and 800 pins dependent upon the package technology utilized. A Sea of I/O approach has been followed to give a solution to today’s problems of drive levels and specialized interface standards. The technology does not utilize a set bond pad spacing but allows for pad spacings from 80 microns upwards. The I/O is fully compatible with that of the ISB35000 Structured Array family. The I/O can be configured for circuits ranging from low voltage CMOS and TTL to 350 mHz plus low swing differential circuits. Standards like GTL, SCSI-2, 3.3 Volt PCI, CTI, and a limited set of 5.0 Volt interfaces are currently being addressed. A specialized set of impedance matched transmission line driver LVTTL type circuits are also available with 25, 35, 45, and 55 Ohm output impedance. These buffers sacrifice direct current capabilities for matching positive and negative voltage and current waveforms.

For these reasons a wide range of cells with different ranges of driving capability are available in the library. The library cells have been optimized in term of functional and electrical parameters in order to have: ■ Good balancing ■ Maximum speed ■ Optimum Threshold voltage ■ Symmetric Vdd/Vss Noise margin ■ Minimum Power-Speed figure Surrounding the core are configurational specialized transistors forming a Sea of I/O giving a high degree of flexibility to the system designer. The geometrical aspect of the cells was configured to allow extremely dense design, fully 10 Êm exploiting the features of the Place and Route tool in terms of horizontal and vertical routing grids. For Place and Route, three levels of metal are utilized. Intracell and intercell wiring are limited to first metal, with second and third metal levels dedicated to interconnect wiring and power distribution. Each cell gives the possibility to use 10 horizontal wiring channels using third metal. With the horizontal grid unit being the same as the Metal 2 minimum contacted pitch, the vertical wiring can be done on every grid point, without limitation. TECHNOLOGY OVERVIEW A major feature of the HCMOS5S process is salicided active areas. This results in source drain areas that are of one to two ohms resistance as opposed to the hundreds or thousands of ohms of source drain resistance in previous technologies. This very low resistance is one reason that very low transistor widths could be utilized in the cell design since drive is not lost due to source drain resistance. This use of low width transistors results in lower capacitance loading of the gates due to the smaller areas utilized. Low resistance, low capacitance, and small gates results in low power usage for inverters as compared to previous technologies. The reduction in power consumption allows the usage of salicided active stripes to distribute power internally to the simple cell, replacing, in some cases, the usage of the first metal layer. This saves silicon area by allowing greater density, permeability and routability of the cells resulting in greater overall circuit density. The standard power distributions are Internal Vdd and Vss, serving the internal cells and the prebuffer sections of the I/O, External Vdd and Vss serving the output transistors only, and Receiver Vdd and Vss serving the first stages of the receiver cells. Optional distributions for 5.0V interface, GTL, CTL, and other standards can be utilized as necessary. Figure 2. ND2 Core Cell 3/16 CB35000 SERIES LIBRARY The following section details the elements which make up the CB35000 Series library. The elements are organized into three categories: 1. Macrocell library with Input, Output, Bidirectional Buffers including JTAG macrocells and Core cells. 2. Macrofunctions 3. Module generators. I/O BUFFERS CB35000 technology does not utilize a standard type I/O cell but is a leader in the emerging Sea of I/O approach to handling the chip interface problem. This approach starts at the bond pad area of the I/O where the pad size and pitch is not determined until the customers choice of packaging, signal interface standards and I/O count is considered. Wire bond pad spacings for 80 micron centres are available where large signal counts are most important. Pad spacing can be increased incrementally. It is expected that most designs will use 100 micron spacings or above. It is also possible to use different spacings for different width output sections when needed within the same device. Along with the variable bond pad spacing the I/O output transistor section does not have a fixed width. Previous technologies utilized a design approach where the desired full function buffer was designed for a maximum current taking one pad location with the usual current in the range of twenty four milliamps. The approach followed in CB35000 is to have identical twenty five micron wide output transistor slices stepped around the die. Each slice contains one set of protection diodes to the external power rails and eight P and eight N transistors. The transistors are specifically laid out and selectively non salicided for ESD protection and latch up prevention. These slices are paralleled to meet the current needs of the user, for example, to construct a 24mA sink and 12mA source LVTTL buffer, a number of slices would be used. The next group of devices that makes up the I/O circuits is again 4/16 a 25u wide slice of specialized transistors that are utilized to form the slew rate control sections of the I/O. Each of these slices has circuits to control the switching of up two sections of P and N output transistors. These sections are of course created from the output transistor slice above the slew rate section and can be connected as desired by the designer. Many configurations of circuits can be created to supply the desired results with slew rate slices paralleled with multiple output sections. A further function of the I/O circuits is current spike suppression during switching of the I/O transistors. The logic utilized causes the conducting transistors to turn off before the opposing set of transistors turn on.

The technologies supported match the output buffer capabilities and include, LVCMOS, LVTTL, GTL, CTL, Differential, etc. and a five volt interface capability. All pads except the sixteen corner pads can be configured as power or I/O pads. The configured power pads are known as placeable pads and have an associated current handling capability. Their placement is dependent on the types of output buffers used in the design. For rules governing the placement of pads, please contact your local SGS-THOMSON design centre. CORE LOGIC The propagation delays shown in the CB35000 data book are given for nominal processing, 3.3V operation, and 25 C temperature conditions. Inside the slew rate sections the next slices of specialized designed components step on a 50 micron wide pattern. The first of these 50 micron wide sections is utilized for predriver circuits; these include specialized built in test functions for the I/O. The predriver of course interfaces the core signals controlling tristate and switching functions with the slew rate and output transistor sections but it also allows all Output Buffers to be driven high, low or put into tristate regardless of the state of the internal logic greatly simplifying parametric testing of the part and also assisting customers who wish to use this feature during board testing. Note that all output buffers can be tristated by this function including buffers that normally do not tristate. This test function also turns off all pull up or down devices and shuts down all differential receivers and converts them into standard CMOS receivers. Inside the predriver is a section of specialized transistors used to create the receiver functions. This section includes specialized non salicide protection resistor diodes to further protect the gates of the receiver devices from ESD and latch up. Also present in this section are devices that can be utilized to form various parameteriseable pull up, pull down and buskeeper functions. A full set of standard receivers with pull up and pull 6/16 However there are additional factors that affect the delay characteristics of the macrocells. These include loading due to fanout and interconnect routing, voltage supply, junction temperature of the device, processing tolerance and input signal transition time. Prior to physical layout, the design system can estimate the delays associated with any critical path. The impact of the placement and routing can be accurately RC back annotated from the layout for final simulations of critical timing. The effects of junction temperature, (KT) and voltage supply (KV) on the delay numbers are summarized in Table 4. A third factor, is associated with process variation. This multiplier has a minimum of 0.8 and a maximum of 1.2. MACROCELLS AND MACROFUNCTIONS The CB35000 series has internal macrocells that are robust in variety and performance. The cell selection has been driven by the need of Synthesis and HDL based design techniques. This offering is rich in buffers, complex combinatorial cells and multi power drive cells, which allow the Synthesis tool to create a netlist compatible with the requirements of Place and Route tools. Macrofunctions are a series of soft-macros facilitating quick capture of large functional blocks and are available for such functions as counters, CB35000 SERIES Table 5 Module Generator Library Cell Description SPRAM 256K bits max 16K word max 64 bit max Zero static current, Tristate outputs DPRAM 128K bits max 8K word max 64 bit max Zero static current, Tristate outputs ROM 2M bits max 32K word max 64 bit max Diffusion programmable, Tristate outputs MULT Parallel asynchronous operation 2’s complement product 6 to 64 bits for both inputs Ripple Carry or Fast Carry Look Ahead shift register and adders. Macrofunctions are implemented at layout by utilizing macrocells and interconnecting to create the logic function. MODULE GENERATORS A series of module generators using compiled cell generation techniques, are available to support a range of megacells. These modules enable the designer to choose individual parameters in order to create a compiled cell, which meets the specific application requirements. These include single port RAM, dual port RAM, ROM and MULT. The compiled cell generators construct custom cells, which are implemented using a special leaf cell technique, ensuring predictable layout and accurate module characteristics. In choosing megacells the designer can consider the trade-offs between speed and area to generate a fully customized cell which meets their specific device requirements. These megacell generators are complemented by a group of application specific embedded megacells. These allow access to technologies that have been hitherto the domain of standard products. Examples include mixed mode cells for graphics, DAC/ADC’s (4-9 bit), PLL applications, and Digital Signal Processor functions for cellular comms, fax and high-speed modem.which initially consist of a Triple 8-bit DAC, Graphics RAM, Clock Multiplier PLL and Frequency Synthesis PLL. 100 Mbps serial transputer links coupled with large and fast memory can be used for pipelining, caching and synchro circuits in modern RISC computing architectures. Viterbi and Reed Solomon cores aim at the HDTV and satellite transmission markets. To support telecom needs for CCITT standard applications, ADPCM cells supporting CT2 protocol have been developed. DESIGN FOR TESTABILITY The time and cost for ASIC testing increases exponentially as the complexity and size of the ASIC grows. Using a design for testability methodology allows large, more complex ASICs to be efficiently and economically tested. CB35000 supports the JTAG boundary Scan and both edge and level sensitive scan design techniques by providing the necessary macrocells. Scan testing aids device testability by permitting access to internal nodes without requiring a separate external connection for each node accessed. Testability is assured at device level with the close coupling of LSSD latch elements, Automatic Test Pattern Generation (ATPG) and high pattern depth tester architecture. BIST options for memory generators are also available. At system level, SGS-THOMSON fully supports IEEE 1149.1, and the I/O structure utilized in this family is completely compatible. Several types of 7/16 CB35000 SERIES core scan cells are provided in the CB35000 Series library. Examples include FDxS/FJKxS cells which are edge sensitive and LSxx cells which are true LSSD cells. Non-overlapping clock generator macros are also available.

The four levels of interface are shown in Figure 7. Level 1 is characterized by SGS-THOMSON receiving the system specification and taking the design through to validation and fabrication. At level 2 interface the designer supplies a complete logic design implemented in a standard generic logic family. SGS-THOMSON then takes the design through to layout, validation and fabrication. Level 3 is the most common and preferred interface level. Logic capture and pre-layout simulation are performed by the designer using an SGS-THOMSON supported design kit.
