virtex-4 family overview ds112 (v3.1) august 30, 2010 www.xilinx.com product specification 4 r architectural description: virtex-4 fpga array overview virtex-4 devices are user-programmable gate arrays with various configurable elements and embedded cores opti- mized for high-density and high-performance system designs. virtex-4 devices implement the following function- ality: ? 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 are enhanced for source-synchronous applications. source-synchronous optimizations include per-bit deskew, data serializer/deserializer, clock dividers, and dedicated local clocking resources. ? configurable logic blocks (clbs), the basic logic elements for xilinx fpgas, provide combinatorial and synchronous logic as well as distributed memory and srl16 shift register capability. ? block ram modules provid e flexible 18kbit true dual-port ram, that are cascadable to form larger memory blocks. in addition, virtex-4 fpga block rams contain optional programmable fifo logic for increased device utilization. ? cascadable embedded xtremedsp slices with 18-bit x 18-bit dedicated multipliers, integrated adder, and 48-bit accumulator. ? digital clock manager (dcm) blocks provide self-calibrating, fully digital solutions for clock distribution delay compensation, clock multiplication/division, and coarse-/fine-grained clock phase shifting. additionally, fx devices support the following embedded system functionality: ? integrated high-speed serial transceivers enable data rates up to 6.5 gb/s per channel. ? embedded ibm powerpc 405 processor risc cpu (up to 450 mhz) with the auxiliary processor unit interface ? 10/100/1000 ethernet media-access control (emac) cores. the general routing matrix (grm) provides an array of rout- ing switches between each component. each programma- ble element is tied to a switch matrix, allowing multiple connections to the general routing matrix. the overall pro- grammable interconnection is hierarchical and designed to support high-speed designs. all programmable elements, including the routing resources, are controlled by values stored in static memory cells. these values are loaded in the memory cells during configuration and can be reloaded to change the functions of the programmable elements. virtex-4 fpga features this section briefly describes the features of the virtex-4 family of fpgas. input/output (selectio) blocks 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 se rializer/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, and 1.5v) ? pci (33 and 66 mhz) ?pci-x ? gtl and gtlp ? hstl 1.5v and 1.8v (class i, ii, iii, and iv) ? sstl 1.8v and 2.5v (class i and ii) the 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 sig- naling i/o standards: ? lvds and extended lvds (2.5v only) ? b lv d s ( b u s lv d s ) ?ulvds ? hypertransport? ? differential hstl 1.5v and 1.8v (class ii) ? differential sstl 1.8v and 2.5v (class ii) 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
virtex-4 family overview ds112 (v3.1) august 30, 2010 www.xilinx.com product specification 5 r range of signal delays. this is especially useful for synchro- nizing signal edges in source synchronous interfaces. general purpose i/o in select locations (four per bank) are designed to be ?regional clock capable? i/o by adding spe- cial 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 clock- ing supplements the global clocking resources. data serializer/des erializer capability is added to every i/o to support source synchronous interfaces. a serial-to-paral- lel converter with associated cloc k divider is included in the input path, and a parallel-to-serial converter in the output path. an in-depth guide to the virtex-4 fpga iob is discussed in the virtex-4 fpga user guide . configurable log ic blocks (clbs) a clb resource is made up of four slices. each slice is equivalent and contains: ? two function generators (f & g) ? two storage elements ? arithmetic logic gates ? large multiplexers ? fast carry look-ahead chain the function generators f & g are configurable as 4-input look-up tables (luts). two slices in a clb can have their luts configured as 16-bit shift registers, or as 16-bit distrib- uted ram. in addition, the two storage elements are 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-4 fpga clbs are further discussed in the virtex-4 fpga user guide . block ram the block ram resources are 18 kb true dual-port ram blocks, programmable from 16k x 1 to 512 x 36, in various depth and width configurations. each port is totally synchro- nous 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, and byte write enable are new features supported in the virtex-4 fpga. the block ram feature in virtex-4 devices is further dis- cussed in the virtex-4 fpga user guide . xtremedsp slices the xtremedsp slices contain a dedicated 18 x 18-bit 2?s complement signed multiplier, adder logic, and a 48-bit accumulator. each multiplier or accumulator can be used independently. these blocks are designed to implement extremely efficient and high-speed dsp applications. the block dsp feature in virtex-4 devices are further dis- cussed in xtremedsp design considerations . global clocking the dcm and global-clock mu ltiplexer buffers provide a complete solution for designing high-speed clock networks. up to twenty dcm blocks are available. 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 higher res- olution phase adjustment with fraction of the clock period increments. flexible frequen cy synthesis provides a clock output frequency equal to a fractional or integer multiple of the input clock frequency. virtex-4 devices have 32 global-clock mux buffers. the clock tree is designed to be differential. differential clocking helps reduce jitter and duty cycle distortion. routing resources all components in virtex-4 devices use the same intercon- nect scheme and the same access to the global routing matrix. timing models are shared, greatly improving the predictability of th e performance for hi gh-speed designs. boundary-scan boundary-scan instructions and associated data registers support a standard methodology for accessing and config- uring virtex-4 devices, complying with ieee standards 1149.1 and 1532. configuration virtex-4 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) optional 256-bit aes de cryption is supported on-chip (with software bitstream encryption) providing intellectual prop- erty security.
