描述

This answer record contains the Release Notes and Known Issues for the Kintex-7 FPGA Base Targeted Reference Design (TRD). 

The purpose of this answer record is to help the user avoid running into issues when performing intended operations with the Base TRD.

解决方案

The Kintex-7 FPGA Base TRD is developed on the Kintex-7 FPGA KC705 Evaluation Kit.

The primary components of the TRD are:

• Integrated Endpoint block for PCI Express
• Northwest Logic Packet DMA
• Multiport Virtual FIFO built using MIG, AXI Interconnect and FIFO Generator IP cores

Hardware Test Setup Requirements

(Xilinx Answer 55926) - Kintex-7 FPGA KC705 Evaluation Kit - Recommended machines for Kintex-7 FPGA Base Targeted Reference Design

The prerequisites required to run and test the Base TRD are:

• KC705 Evaluation kit with the XC7K325T-2FFG900C FPGA
• Design files provided on a USB memory stick as a zipped collection including:
• Design source files
• Device driver files
• Board design files
• Documentation
• ISE Design Suite, Logic Edition v13.4 or later
• Micro USB cable
• PCIe adapter cable, 4-Pin to 6-Pin
• Fedora 16 Live DVD for Intel-compatible PCs or pre-installed Fedora 16 Linux OS
• PC with PCIe v2.0 slot.

Simulation Requirements

The tools required to simulate the Base TRD are:

• ISE Design Suite, Logic Edition v13.4 or later
• ModelSim simulation software, v6.6d or later

Kintex-7 Base TRD v1.0 for ISE 13.4 with GES Silicon

• Silicon
• The Kintex-7 FPGA KC705 Evaluation Kit ships with GES silicon. Refer to GES Errata for any further information.
• IP Cores
• Memory Controller (MIG): The TRD uses custom MIG Files (Xilinx Answer 45680)
• Targeted Reference Design
  • DDR3 fails to calibrate (Xilinx Answer 45681)
  • Base TRD driver does not unload successfully (Xilinx Answer 45847)
  • DMA performance on Base TRD fluctuates and is lower than expected (Xilinx Answer 45848)
  • Fedora 16 may not boot on all PCs (Xilinx Answer 45845)
  • Systems with low memory may crash when trying to run the Kintex-7 Base TRD (Xilinx Answer 46017)
• Tools
• TRD source files only available in Verilog
• TRD has not been synthesized with Synplicity
• TRD was simulated with ModelSim 6.6d
• ISIM support is not available
• The supported operating system is 32-bit Fedora 16 Linux. Windows driver support is not available
• When implementing the design in the PlanAhead flow, 50 Critical warnings are reported with regards to clock period (REFCLK_PERIOD, MEMREFCLK_PERIOD, PHASEREFCLK_PERIOD). Ignore these warnings.
  The issue will be fixed in the next version of the ISE design tools.
• If design files are changed, there is a possibility that timing will not be met. Users may need to run MAP with different cost table values to meet timing.
  The implementation script allows the user to set a cost table value. Use the tag option of implement.sh to make output directories unique.
  Every effort has been made to have the default cost table meet timing, however due to varying conditions the default cost table cannot be guaranteed to meet timing.
