Virtex™ 2.5 V Field Programmable Gate Arrays R Product Obsolete/Under ObsolescenceVirtex Architecture Virtex devices feature a flexible, regular architecture that comprises an array of configurable logic blocks (CLBs) sur- rounded by programmable input/output blocks (IOBs), all interconnected by a rich hierarchy of fast, versatile routing resources. The abundance of routing resources permits the Virtex family to accommodate even the largest and most complex designs. Virtex FPGAs are SRAM-based, and are customized by loading configuration data into internal memory cells. In some modes, the FPGA reads its own configuration data from an external PROM (master serial mode). Otherwise, the configuration data is written into the FPGA (Select- MAP™, slave serial, and JTAG modes). The standard Xilinx Foundation™ and Alliance Series™ Development systems deliver complete design support for Virtex, covering every aspect from behavioral and sche- matic entry, through simulation, automatic design transla- tion and implementation, to the creation, downloading, and readback of a configuration bit stream. Higher Performance Virtex devices provide better performance than previous generations of FPGA. Designs can achieve synchronous system clock rates up to 200 MHz including I/O. Virtex inputs and outputs comply fully with PCI specifications, and interfaces can be implemented that operate at 33 MHz or 66 MHz. Additionally, Virtex supports the hot-swapping requirements of Compact PCI. Xilinx thoroughly benchmarked the Virtex family. While per- formance is design-dependent, many designs operated internally at speeds in excess of 100 MHz and can achieve 200 MHz. Table 2 shows performance data for representa- tive circuits, using worst-case timing parameters.

Product Obsolete/Under ObsolescenceArchitectural Description Virtex Array The Virtex user-programmable gate array, shown in Figure 1, comprises two major configurable elements: con- figurable logic blocks (CLBs) and input/output blocks (IOBs). • CLBs provide the functional elements for constructing logic • IOBs provide the interface between the package pins and the CLBs CLBs interconnect through a general routing matrix (GRM). The GRM comprises an array of routing switches located at the intersections of horizontal and vertical routing channels. Each CLB nests into a VersaBlock™ that also provides local routing resources to connect the CLB to the GRM. The VersaRing™ I/O interface provides additional routing resources around the periphery of the device. This routing improves I/O routability and facilitates pin locking. The Virtex architecture also includes the following circuits that connect to the GRM. • Dedicated block memories of 4096 bits each • Clock DLLs for clock-distribution delay compensation and clock domain control • 3-State buffers (BUFTs) associated with each CLB that drive dedicated segmentable horizontal routing resources Values stored in static memory cells control the configurable logic elements and interconnect resources. These values load into the memory cells on power-up, and can reload if necessary to change the function of the device. Input/Output Block The Virtex IOB, Figure 2, features SelectIO™ inputs and outputs that support a wide variety of I/O signalling stan- dards, see Table 1. The three IOB storage elements function either as edge-trig- gered D-type flip-flops or as level sensitive latches. Each IOB has a clock signal (CLK) shared by the three flip-flops and independent clock enable signals for each flip-flop. In addition to the CLK and CE control signals, the three flip-flops share a Set/Reset (SR). For each flip-flop, this sig- nal can be independently configured as a synchronous Set, a synchronous Reset, an asynchronous Preset, or an asyn- chronous Clear. The output buffer and all of the IOB control signals have independent polarity controls. All pads are protected against damage from electrostatic discharge (ESD) and from over-voltage transients. Two forms of over-voltage protection are provided, one that per- mits 5 V compliance, and one that does not. For 5 V compli- ance, a Zener-like structure connected to ground turns on when the output rises to approximately 6.5 V. When PCI 3.3 V compliance is required, a conventional clamp diode is connected to the output supply voltage, VCCO. Optional pull-up and pull-down resistors and an optional weak-keeper circuit are attached to each pad. Prior to con- figuration, all pins not involved in configuration are forced into their high-impedance state. The pull-down resistors and the weak-keeper circuits are inactive, but inputs can option- ally be pulled up. The activation of pull-up resistors prior to configuration is controlled on a global basis by the configuration mode pins. If the pull-up resistors are not activated, all the pins will float. Consequently, external pull-up or pull-down resistors must be provided on pins required to be at a well-defined logic level prior to configuration. All Virtex IOBs support IEEE 1149.1-compatible boundary scan testing. 0 Virtex™ 2.5 V Field Programmable Gate Arrays DS003-2 (v4.0) March 1, 2013 0 0 Product Specification R Figure 1: Virtex Architecture Overview vao_b.eps IOBs IOBs IO B s IO B s DLL DLLDLL DLL VersaRing V e rs a R in g VersaRing V e rs a R in g CLBs B R A M s B R A M s © 1999-2013 Xilinx, Inc.

Virtex™ 2.5 V Field Programmable Gate Arrays R Product Obsolete/Under ObsolescenceInput Path A buffer In the Virtex IOB input path routes the input signal either directly to internal logic or through an optional input flip-flop. An optional delay element at the D-input of this flip-flop elim- inates pad-to-pad hold time. The delay is matched to the internal clock-distribution delay of the FPGA, and when used, assures that the pad-to-pad hold time is zero. Each input buffer can be configured to conform to any of the low-voltage signalling standards supported. In some of these standards the input buffer utilizes a user-supplied threshold voltage, VREF. The need to supply VREF imposes constraints on which standards can used in close proximity to each other. See I/O Banking, page 3. There are optional pull-up and pull-down resistors at each user I/O input for use after configuration. Their value is in the range 50 kΩ – 100 kΩ. Output Path The output path includes a 3-state output buffer that drives the output signal onto the pad. The output signal can be routed to the buffer directly from the internal logic or through an optional IOB output flip-flop. The 3-state control of the output can also be routed directly from the internal logic or through a flip-flip that provides syn- chronous enable and disable. Each output driver can be individually programmed for a wide range of low-voltage signalling standards. Each output buffer can source up to 24 mA and sink up to 48mA. Drive strength and slew rate controls minimize bus transients. In most signalling standards, the output High voltage depends on an externally supplied VCCO voltage. The need to supply VCCO imposes constraints on which standards can be used in close proximity to each other. See I/O Bank- ing, page 3. An optional weak-keeper circuit is connected to each out- put. When selected, the circuit monitors the voltage on the pad and weakly drives the pin High or Low to match the input signal. If the pin is connected to a multiple-source sig- nal, the weak keeper holds the signal in its last state if all drivers are disabled. Maintaining a valid logic level in this way eliminates bus chatter. Because the weak-keeper circuit uses the IOB input buffer to monitor the input level, an appropriate VREF voltage must be provided if the signalling standard requires one. The pro- vision of this voltage must comply with the I/O banking rules. I/O Banking Some of the I/O standards described above require VCCO and/or VREF voltages. These voltages externally and con- nected to device pins that serve groups of IOBs, called banks. Consequently, restrictions exist about which I/O standards can be combined within a given bank. Eight I/O banks result from separating each edge of the FPGA into two banks, as shown in Figure 3. Each bank has multiple VCCO pins, all of which must be connected to the same voltage. This voltage is determined by the output standards in use. Within a bank, output standards can be mixed only if they use the same VCCO. Compatible standards are shown in Table 2. GTL and GTL+ appear under all voltages because their open-drain outputs do not depend on VCCO. Some input standards require a user-supplied threshold voltage, VREF. In this case, certain user-I/O pins are auto- matically configured as inputs for the VREF voltage. Approx- imately one in six of the I/O pins in the bank assume this role. The VREF pins within a bank are interconnected internally and consequently only one VREF voltage can be used within each bank. All VREF pins in the bank, however, must be con- nected to the external voltage source for correct operation. Within a bank, inputs that require VREF can be mixed with those that do not. However, only one VREF voltage can be used within a bank. Input buffers that use VREF are not 5 V tolerant. LVTTL, LVCMOS2, and PCI 33 MHz 5 V, are 5 V tolerant. The VCCO and VREF pins for each bank appear in the device Pinout tables and diagrams. The diagrams also show the bank affiliation of each I/O. Within a given package, the number of VREF and VCCO pins can vary depending on the size of device.

Virtex™ 2.5 V Field Programmable Gate Arrays R Product Obsolete/Under Obsolescencemore I/O pins convert to VREF pins. Since these are always a superset of the VREF pins used for smaller devices, it is possible to design a PCB that permits migration to a larger device if necessary. All the VREF pins for the largest device anticipated must be connected to the VREF voltage, and not used for I/O. In smaller devices, some VCCO pins used in larger devices do not connect within the package. These unconnected pins can be left unconnected externally, or can be connected to the VCCO voltage to permit migration to a larger device if necessary. In TQ144 and PQ/HQ240 packages, all VCCO pins are bonded together internally, and consequently the same VCCO voltage must be connected to all of them. In the CS144 package, bank pairs that share a side are intercon- nected internally, permitting four choices for VCCO. In both cases, the VREF pins remain internally connected as eight banks, and can be used as described previously. Configurable Logic Block The basic building block of the Virtex CLB is the logic cell (LC). An LC includes a 4-input function generator, carry logic, and a storage element. The output from the function generator in each LC drives both the CLB output and the D input of the flip-flop. Each Virtex CLB contains four LCs, organized in two similar slices, as shown in Figure 4. Figure 5 shows a more detailed view of a single slice. In addition to the four basic LCs, the Virtex CLB contains logic that combines function generators to provide functions of five or six inputs. Consequently, when estimating the number of system gates provided by a given device, each CLB counts as 4.5 LCs. Look-Up Tables Virtex function generators are implemented as 4-input look-up tables (LUTs). In addition to operating as a function generator, each LUT can provide a 16 x 1-bit synchronous RAM. Furthermore, the two LUTs within a slice can be com- bined to create a 16 x 2-bit or 32 x 1-bit synchronous RAM, or a 16x1-bit dual-port synchronous RAM. The Virtex LUT can also provide a 16-bit shift register that is ideal for capturing high-speed or burst-mode data. This mode can also be used to store data in applications such as Digital Signal Processing. Storage Elements The storage elements in the Virtex slice can be configured either as edge-triggered D-type flip-flops or as level-sensi- tive latches. The D inputs can be driven either by the func- tion generators within the slice or directly from slice inputs, bypassing the function generators. In addition to Clock and Clock Enable signals, each Slice has synchronous set and reset signals (SR and BY). SR forces a storage element into the initialization state speci- fied for it in the configuration. BY forces it into the opposite state. Alternatively, these signals can be configured to oper- ate asynchronously. All of the control signals are indepen- dently invertible, and are shared by the two flip-flops within the slice.

Virtex™ 2.5 V Field Programmable Gate Arrays R Product Obsolete/Under ObsolescenceAdditional Logic The F5 multiplexer in each slice combines the function gen- erator outputs. This combination provides either a function generator that can implement any 5-input function, a 4:1 multiplexer, or selected functions of up to nine inputs. Similarly, the F6 multiplexer combines the outputs of all four function generators in the CLB by selecting one of the F5-multiplexer outputs. This permits the implementation of any 6-input function, an 8:1 multiplexer, or selected func- tions of up to 19 inputs. Each CLB has four direct feedthrough paths, one per LC. These paths provide extra data input lines or additional local routing that does not consume logic resources. Arithmetic Logic Dedicated carry logic provides fast arithmetic carry capabil- ity for high-speed arithmetic functions. The Virtex CLB sup- ports two separate carry chains, one per Slice. The height of the carry chains is two bits per CLB. The arithmetic logic includes an XOR gate that allows a 1-bit full adder to be implemented within an LC. In addition, a dedicated AND gate improves the efficiency of multiplier implementation. The dedicated carry path can also be used to cascade func- tion generators for implementing wide logic functions. BUFTs Each Virtex CLB contains two 3-state drivers (BUFTs) that can drive on-chip busses. See Dedicated Routing, page 7. Each Virtex BUFT has an independent 3-state control pin and an independent input pin. Block SelectRAM Virtex FPGAs incorporate several large block SelectRAM memories. These complement the distributed LUT SelectRAMs that provide shallow RAM structures imple- mented in CLBs. Block SelectRAM memory blocks are organized in columns. All Virtex devices contain two such columns, one along each vertical edge. These columns extend the full height of the chip. Each memory block is four CLBs high, and conse- quently, a Virtex device 64 CLBs high contains 16 memory blocks per column, and a total of 32 blocks. Table 3 shows the amount of block SelectRAM memory that is available in each Virtex device.
