7 Series Integrated Block for PCI Express - x8 Gen 1 and x4 Gen 2 designs using 128-bit interface do not simulate
Version Found: v1.1
Version Resolved and other Known Issues: See (Xilinx Answer 40469).
A x8 Gen1 or x4 Gen2 design using the 128-bit interface does not link up during simulation.
Note: "Version Found" refers to the version the problem was first discovered. The problem may also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
This is due to incorrect attribute settings and a port width mistake in the root port simulation design.
Tocorrect this problem,edit the "board.v" file found in the generated core's simulation/functional/ directory.
In the instance of xilinx_pcie_2_1_rport_v7, make the following attribute modifications:
Change TRN_DW from TRUE to FALSE
Change USER_CLK2_DIV2 from True to FALSE
In the simulation/dsport directory, edit pcie_2_1_rp_v7.v and make the following modifications:
Change the trn_rd and trn_td ports from [127:0] to [63:0]
Change trn_rrem and trn_trem from [1:0] to just a single bit (i.e., delete the "[1:0]" designation).
