This article contains issues resolved in theSpartan-6 FPGA Integrated Block v2.1 Wrapper for PCI Express that are alsolisted 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 45702).


Resolved Issues

  • Default simulation test has been upgraded
    • CR 571633, 532234
    • Default simulation test has been upgraded to include memory and I/O reads and writes.
  • cfg_msg_* interface ports on Root Port Model now visible
    • CR 568527
    • cfg_msg_* ports are now visible at the top level of the Root Port Model delivered with Endpoint product.
  • Syntax error in VHDL instantiation template
    • CR 572307
    • Syntax error in the VHDL instantiation template was corrected.
  • User non-posted OK signal undriven in VHDL Root Port model
    • CR 568356
    • Issue resolved where the User non-posted OK signal was undriven in the VHDL Root Port model, preventing memory read transactions from passing to the User Interface.
  • ACK Transmission Latency to Large
    • CR 565726
    • Issue resolved where the ACK transmission latency was to large, causing Replay timer on connected component trigger, thus generating an error.
