Virtex-6 FPGA Integrated Block Wrapper for PCI Express - Resolved issues in v2.2

Description

This article contains issues resolved in the Virtex-6 FPGA Integrated Block v2.2 Wrapper for PCI Express that are also listed in the readme.txt file that accompanies this version of the core. These are issues that were fixed as part of the update from the previous version of the core.

For other known and resolved issues that may not be in this list see (Xilinx Answer 45723)

Solution

Resolved Issues
  • VHDL source code generation support added.
    • CR 575119
    • VHDL source code generation now supported. Also includes Example Design, testbench and simulation and implementation scripts.
  • 8-lane Gen2 Endpoint Configuration in a -2 Speed Grade device
    • CR 581873
    • The 8-lane Gen2 Endpoint Configuration, in a -2 Speed Grade device, has been restricted to "High" performance Level, as the "Good" Performance Level block RAM cannot be run at 500 MHz as required for this configuration.
  • INTERRUPT_PIN attribute update based on Legacy Interrupt option in GUI
    • CR 581046
    • Issue resolved where Unchecking the Legacy Interrupt option was not updating the INTERRUPT_PIN attribute.
  • Timing path ignored in Flat flow but analyzed in Hierarchical flow
    • CR 576025
    • Timing improvement for 8-lane Gen2 Configuration : Timing Ignore (TIG) added to sel_lnk_rate path. This path was being analyzed in hierarchical flow causing failure to meet timing.
