描述

This answer record highlights important requirements and known issues for the Kintex-7 FPGA Initial Engineering Sample (ES) program related to software and IP.

These items are specifically relevant to designs targeting the Kintex-7 325T and 480T Initial ES FPGA devices (CES 9937). Additional silicon limitations might exist, so please reference the 7 Series Errata found on xilinx.com.

This answer record will be updated as new information becomes available regarding known issues, patches, IP support, and more. Please check back often for the most current information.

解决方案

Kintex-7 Initial ES FPGA can be used with ISE 13.4 design tools. The ISE 13.4 tools include some software and IP fixes, however, it is primarily targeted for General ES devices, so some additional settings are required. 

Follow the steps listed below for your ISE tools version in the Software Requirements and IP Known Issues to start a design.

Software Requirements

• ISE Design Suite 13.4 is available on the Xilinx Download Center.
• Patches; this is the complete list of available patches for ISE 13.4 design tools targeting the Kintex-7 FPGA Initial ES silicon.
  
  • Required patches for all users:
    • (Xilinx Answer 43060) - Any user creating a bitstream for the Kintex-7 325T Initial ES device must install this BitGen patch.

Software Known Issues

IP Requirements

All 7 Series IP Cores are listed as Pre-Production in the CORE Generator "Status" field. Support of Pre-Production cores on Initial ES FPGA devices is dependent on Xilinx hardware validation, which is ongoing throughout the ES period. IP that has been hardware validated is still subject to change as verification and characterization work continues. Consult the IP Known Issues Answer Records below for the most recent information. The list below includes all Pre-Production IP cores that have been hardware validated on Initial ES at this time:

• 7 Series Integrated Block for PCI Express
• MIG 7 Series DDR3 SDRAM, QDR II+ SRAM, and RLDRAM II
• Serial RapidIO Gen2 (v1.3) at 1.25 Gb/s, 2.5 Gb/s, and 3.125 Gb/s line rates

This list will be updated as hardware validation is completed. If there are further questions about hardware validation for a particular IP core, please contact a Field Application Engineer.

IP Known Issues for ISE Design Suite 13.4

• 7 Series Integrated Block for PCI Express
  • All users of the Integrated Block for PCIe must update to ISE Design Suite 13.4 and use core version v1.3
  • (Xilinx Answer 40469) 7 Series Integrated Block Wrapper for PCI Express - Release Notes and Known Issues
  • (Xilinx Answer 43243) Virtex-7, Kintex-7 FPGA XC7K325T CES9937 Integrated Block for PCI Express - Active State Power Management Not Supported for Gen 2 Rates
  • The v1.3 core gives users an option of selecting between Initial ES (ES) and General ES (GES) silicon. When generating the core, there is a drop-down on panel 12 (last panel) of the customization GUI to select either "General ES" or "Initial ES" silicon. The same bitstream cannot be used in both IES and GES devices.
• LogiCORE IP AXI EP Bridge for PCI Express (EDK)
  
  • All users of the AXI EP Bridge for PCI Express available in EDK must update to ISE Design Suite 13.4 and use core version v1.02a
  • (Xilinx Answer 44969) AXI Bridge for PCI Express - Release Notes and Known Issues for All Versions
• MIG 7 Series DDR3 SDRAM, QDR II+ SRAM, and RLDRAM II
  • MIG 7 Series users need to use MIG 7 Series v1.4 available with ISE Design Suite 13.4 or later due to updated calibration changes and CKE/ODT implementation changes as outlined in (Xilinx Answer 45633) Design Advisory for 7 Series MIG DDR3/DDR2 - Updated pin placement rules for CKE and ODT; existing UCFs must be verified
