Virtex-5 devices implement the following functionality: • • • I/O blocks provide the interface between package pins and the internal configurable logic. Most popular and leading-edge I/O standards are supported by programmable I/O blocks (IOBs). The IOBs can be connected to very flexible ChipSync logic for enhanced source-synchronous interfacing. Source-synchronous optimizations include per-bit deskew (on both input and output signals), data serializers/deserializers, clock dividers, and dedicated I/O and local clocking resources. Additionally, LXT, SXT, TXT, and FXT devices also contain: Configurable Logic Blocks (CLBs), the basic logic elements for Xilinx® FPGAs, provide combinatorial and synchronous logic as well as distributed memory and SRL32 shift register capability. Virtex-5 FPGA CLBs are based on real 6-input look-up table technology and provide superior capabilities and performance compared to previous generations of programmable logic. • Block RAM modules provide flexible 36 Kbit true dualport RAM that are cascadable to form larger memory blocks. In addition, Virtex-5 FPGA block RAMs contain optional programmable FIFO logic for increased device utilization. Each block RAM can also be configured as two independent 18 Kbit true dual-port RAM blocks, providing memory granularity for designs needing smaller RAM blocks. • Cascadable embedded DSP48E slices with 25 x 18 two’s complement multipliers and 48-bit adder/subtracter/accumulator provide massively parallel DSP algorithm support. In addition, each DSP48E slice can be used to perform bitwise logical functions. • Clock Management Tile (CMT) blocks provide the most flexible, highest-performance clocking for FPGAs. Each CMT contains two Digital Clock Manager (DCM) blocks (self-calibrating, fully digital), and one PLL block (selfcalibrating, analog) for clock distribution delay compensation, clock multiplication/division, coarse/fine-grained clock phase shifting, and input clock jitter filtering. 6 • Integrated Endpoint blocks for PCI Express designs providing x1, x4, or x8 PCI Express Endpoint functionality. When used in conjunction with RocketIO transceivers, a complete PCI Express Endpoint can be implemented with minimal FPGA logic utilization. • 10/100/1000 Mb/s Ethernet media-access control blocks offer Ethernet capability. LXT and SXT devices contain: RocketIO GTP transceivers capable of running up to 3.75 Gb/s. Each GTP transceiver supports full-duplex, clock-and-data recovery. TXT and FXT devices contain: • GTX transceivers capable of running up to 6.5 Gb/s. Each GTX transceiver supports full-duplex, clock-anddata recovery. FXT devices contain: • Embedded IBM PowerPC 440 RISC CPUs. Each PowerPC 440 CPU is capable of running up to 550 MHz. Each PowerPC 440 CPU also has an APU (Auxiliary Processor Unit) interface that supports hardware acceleration, and an integrated cross-bar for high data throughput. The general routing matrix (GRM) provides an array of routing switches between each internal component. Each programmable element is tied to a switch matrix, allowing multiple connections to the general routing matrix. The overall programmable interconnection is hierarchical and designed to support high-speed designs. In Virtex-5 devices, the routing connections are optimized to support CLB interconnection in the fewest number of “hops.” Reducing hops greatly increases post place-and-route (PAR) design performance. All programmable elements, including the routing resources, are controlled by values stored in static storage elements. These values are loaded into the FPGA during configuration and can be reloaded to change the functions of the programmable elements. www.xilinx.com DS100 (v5.0) February 6, 2009 Product Specification R Virtex-5 Family Overview Virtex-5 FPGA Features This section briefly describes the features of the Virtex-5 family of FPGAs. Input/Output Blocks (SelectIO) IOBs are programmable and can be categorized as follows: • Programmable single-ended or differential (LVDS) operation • Input block with an optional single data rate (SDR) or double data rate (DDR) register • Output block with an optional SDR or DDR register • Bidirectional block • Per-bit deskew circuitry • Dedicated I/O and regional clocking resources • Built-in data serializer/deserializer The IOB registers are either edge-triggered D-type flip-flops or level-sensitive latches. IOBs support the following single-ended standards: • LVTTL • LVCMOS (3.3V, 2.5V, 1.8V, 1.5V, and 1.2V) • PCI (33 and 66 MHz) • PCI-X • GTL and GTLP • HSTL 1.5V and 1.8V (Class I, II, III, and IV) • HSTL 1.2V (Class 1) • SSTL 1.8V and 2.5V (Class I and II) The Digitally Controlled Impedance (DCI) I/O feature can be configured to provide on-chip termination for each single-ended I/O standard and some differential I/O standards. The IOB elements also support the following differential signaling I/O standards: • LVDS and Extended LVDS (2.5V only) • BLVDS (Bus LVDS) • ULVDS • Hypertransport™ • Differential HSTL 1.5V and 1.8V (Class I and II) • Differential SSTL 1.8V and 2.5V (Class I and II) • RSDS (2.5V point-to-point) Two adjacent pads are used for each differential pair. Two or four IOB blocks connect to one switch matrix to access the routing resources. Per-bit deskew circuitry allows for programmable signal delay internal to the FPGA. Per-bit deskew flexibly provides fine-grained increments of delay to carefully produce a range of signal delays. This is especially useful for synchronizing signal edges in source-synchronous interfaces. Data serializer/deserializer capability is added to every I/O to support source-synchronous interfaces. A serial-toparallel converter with associated clock divider is included in the input path, and a parallel-to-serial converter in the output path. An in-depth guide to the Virtex-5 FPGA IOB is found in the Virtex-5 FPGA Tri-Mode Ethernet MAC User Guide. Configurable Logic Blocks (CLBs) A Virtex-5 FPGA CLB resource is made up of two slices. Each slice is equivalent and contains: • Four function generators • Four storage elements • Arithmetic logic gates • Large multiplexers • Fast carry look-ahead chain The function generators are configurable as 6-input LUTs or dual-output 5-input LUTs. SLICEMs in some CLBs can be configured to operate as 32-bit shift registers (or 16-bit x 2 shift registers) or as 64-bit distributed RAM. In addition, the four storage elements can be configured as either edge-triggered D-type flip-flops or level sensitive latches. Each CLB has internal fast interconnect and connects to a switch matrix to access general routing resources. The Virtex-5 FPGA CLBs are further discussed in the Virtex-5 FPGA User Guide. Block RAM The 36 Kbit true dual-port RAM block resources are programmable from 32K x 1 to 512 x 72, in various depth and width configurations. In addition, each 36-Kbit block can also be configured to operate as two, independent 18Kbit dual-port RAM blocks. Each port is totally synchronous and independent, offering three “read-during-write” modes. Block RAM is cascadable to implement large embedded storage blocks. Additionally, back-end pipeline registers, clock control circuitry, built-in FIFO support, ECC, and byte write enable features are also provided as options. The block RAM feature in Virtex-5 devices is further discussed in the Virtex-5 FPGA User Guide. General purpose I/O in select locations (eight per bank) are designed to be “regional clock capable” I/O by adding special hardware connections for I/O in the same locality. These regional clock inputs are distributed within a limited region to minimize clock skew between IOBs. Regional I/O clocking supplements the global clocking resources. DS100 (v5.0) February 6, 2009 Product Specification www.xilinx.com 7 R Virtex-5 Family Overview Global Clocking Configuration The CMTs and global-clock multiplexer buffers provide a complete solution for designing high-speed clock networks. Virtex-5 devices are configured by loading the bitstream into internal configuration memory using one of the following modes: • Slave-serial mode • Master-serial mode • Slave SelectMAP mode • Master SelectMAP mode • Boundary-Scan mode (IEEE-1532 and -1149) • SPI mode (Serial Peripheral Interface standard Flash) • BPI-up/BPI-down modes (Byte-wide Peripheral interface standard x8 or x16 NOR Flash) Each CMT contains two DCMs and one PLL. The DCMs and PLLs can be used independently or extensively cascaded. Up to six CMT blocks are available, providing up to eighteen total clock generator elements. Each DCM provides familiar clock generation capability. To generate deskewed internal or external clocks, each DCM can be used to eliminate clock distribution delay. The DCM also provides 90°, 180°, and 270° phase-shifted versions of the output clocks. Fine-grained phase shifting offers higherresolution phase adjustment with fraction of the clock period increments. Flexible frequency synthesis provides a clock output frequency equal to a fractional or integer multiple of the input clock frequency. To augment the DCM capability, Virtex-5 FPGA CMTs also contain a PLL. This block provides reference clock jitter filtering and further frequency synthesis options. Virtex-5 devices have 32 global-clock MUX buffers. The clock tree is designed to be differential. Differential clocking helps reduce jitter and duty cycle distortion. DSP48E Slices DSP48E slice resources contain a 25 x 18 two’s complement multiplier and a 48-bit adder/subtacter/accumulator. Each DSP48E slice also contains extensive cascade capability to efficiently implement high-speed DSP algorithms. The Virtex-5 FPGA DSP48E slice features are further discussed in Virtex-5 FPGA XtremeDSP Design Considerations. Routing Resources All components in Virtex-5 devices use the same interconnect scheme and the same access to the global routing matrix. In addition, the CLB-to-CLB routing is designed to offer a complete set of connectivity in as few hops as possible. Timing models are shared, greatly improving the predictability of the performance for highspeed designs. Boundary Scan Boundary-Scan instructions and associated data registers support a standard methodology for accessing and configuring Virtex-5 devices, complying with IEEE standards 1149.1 and 1532. In addition, Virtex-5 devices also support the following configuration options: • 256-bit AES bitstream decryption for IP protection • Multi-bitstream management (MBM) for cold/warm boot support • Parallel configuration bus width auto-detection • Parallel daisy chain • Configuration CRC and ECC support for the most robust, flexible device integrity checking Virtex-5 device configuration is further discussed in the Virtex-5 FPGA Configuration Guide. System Monitor FPGAs are an important building block in high availability/reliability infrastructure. Therefore, there is need to better monitor the on-chip physical environment of the FPGA and its immediate surroundings within the system. For the first time, the Virtex-5 family System Monitor facilitates easier monitoring of the FPGA and its external environment. Every member of the Virtex-5 family contains a System Monitor block. The System Monitor is built around a 10-bit 200kSPS ADC (Analog-to-Digital Converter). This ADC is used to digitize a number of on-chip sensors to provide information about the physical environment within the FPGA. On-chip sensors include a temperature sensor and power supply sensors. Access to the external environment is provided via a number of external analog input channels. These analog inputs are general purpose and can be used to digitize a wide variety of voltage signal types. Support for unipolar, bipolar, and true differential input schemes is provided. There is full access to the onchip sensors and external channels via the JTAG TAP, allowing the existing JTAG infrastructure on the PC board to be used for analog test and advanced diagnostics during development or after deployment in the field. The System Monitor is fully operational after power up and before configuration of the FPGA. System Monitor does not require an explicit instantiation in a design to gain access to its basic functionality. This allows the System Monitor to be used even at a late stage in the design cycle. The Virtex-5 FPGA System Monitor is further discussed in theVirtex-5 FPGA System Monitor User Guide. 8 www.xilinx.com DS100 (v5.0) February 6, 2009 Product Specification R Virtex-5 Family Overview Virtex-5 LXT, SXT, TXT, and FXT Platform Features This section briefly describes blocks available only in LXT, SXT, TXT, and FXT devices.
