Overview

The DNMEG_V5T_PCIE is a daughter card that adds a PCI Express interface to the many FPGA ASIC prototyping boards from The DINI Group. The PCIe interface can be configured as 1, 4, or 8-lanes. When using Xilinx Virtex-5 LXT or SXT devices, the board is fully compatible with 2.5Gb/s GEN1 PCIe. Gen2 (5.0Gb/s) PCIe functionality is fully supported using the Virtex-5 FX70T-2 (or FX100T-2). When used as a daughter card to the DN9000k10PCIe-8T, an 8-lane PCIe <-> PCIe bridge can be emulated with either (or both) sides GEN1 or GEN2. A treble PCIe bridge can be constructed with two of these daughter cards. The massive 32 million gate DN9000k10 can be converted to a high data bandwidth PCIe master (or peripheral).

A full featured PCIe controller is provided standard. The controller includes master moding DMA. ‘C’ source examples along with drivers are included.

The DNMEG_V5T_PCIE mounts to a DINI base-board using the 400-pin FCI MEG-Array expansion connectors. A small PCIe buffer card (DNPCIe_CBL-D or DNPCIe_CBL-U) is inserted into a host/peripheral PCIe slot and the DNMEG_V5T_PCIE is connected via two, 4-channel iPASS cables. The DNMEG_V5T_PCIE can be used stand-alone.

Xilinx Virtex-5 FPGA

In its standard configuration, the DNMEG_V5T_PCIE is stuffed with a Xilinx Virtex-5 LX110T-1. The LX110T is a relatively large FPGA, containing 69,120 LUT/FF pairs, along with 64, 25×18 multipliers. Five megabytes of internal block memory (296, separate 18kbit blocks) enable the implementation of large scratchpad memories and FIFOs – vital for PCIe applications. The Virtex-5 family has 6-input lookup tables (LUTs), making this FPGA family extremely logic rich. The larger LUT works to reduce the number of logic layers which increases the frequency of operation. Optional stuffing options include the SX50T or SX95T, which has a greater number of embedded multipliers and is optimized for DSP-type applications.

RocketI/O GTP

Eight of the RocketI/O GTP transceivers are used for the 8-lane PCIe interface (via the iPASS cables). Four of the channels are connected to SMA connectors (16 SMA connectors total). The SMA connectors can be used to create a large list of high speed serial interfaces. The most common is Infiniband. A DisplayPort physical interface is added when this board is stuffed with the LX110T or FX70T, SX95T, LX155T, or FX100T. Four RocketI/O GTP channels are needed. An SFP socket shares a RocketI/O GTP with DisplayPort. A wide range of SFP modules is available. The list includes, but is not limited to, 10/100/1000Base-T, SATA, Fibre Channel. The SMAs along with DisplayPort/SFP enable all sorts of PCIe bridges to be emulated: PCIe <-> SATA, PCIe <->1000BaseT, etc.

Memory

A single DDR2 SODIMM socket is connected to the FPGA. This SODIMM socket is tested to 250MHz with a DDR2 SODIMM. Standard, off-the-shelf DDR2 memory DIMMs (PC2-5300) work nicely and we can provide these for a small charge. We have developed alternative SODIMMs that can be stuffed into these positions. Consult the factory for more details, but the list includes FLASH, SSRAM, QDR SSRAM, RLDRAM, SDR SDRAM, mictors, DDR1, DDR3, interconnect, USB Phy, and others. The board includes a DDR2 controller in VHDL and Verilog, and example RocketIO GTP implementations in Verilog, with VHDL is available on request.

Other Features

A Mictor with 28 FPGA connections enables debugging with Tektronix or Agilent Logic Analyzer. Eight user LEDs can be used for all sorts of FPGA-controller visual feedback. The LEDs are bright enough to pull over speeding exotic cars if sequenced correctly. This law enforcement application has not been completely tested.
