Spartan-6 FPGA Integrated Block for PCI Express -WARNING:XdmHelpers:376 - Unexpected value of "1'b0" found for attribute GTP_SEL

Description

Version Found: 1.1; v2.1
Version Resolved and other Known Issues: See (Xilinx Answer 45702).

When implementingthe Spartan-6 FPGA Integrated Block Wrapper for the PCI Express design example, NGDBUILD gives the following warnings:

"WARNING:XdmHelpers:376 - Unexpected value of "1'b0" found for attribute GTP_SEL. Unable to convert this to the expected numeric value.
WARNING:XdmHelpers:376 - Unexpected value of "1'b0" found for attribute GTP_SEL. Unable to convert this to the expected numeric value.
WARNING:NgdBuild:1403 - edif property 'GTP_SEL' of type 'string' on object 'PCIE_A1' is being ignored. It is recognized property but does not have the expected type of 'integer'."

These messages appear onlywhen using Synplify to synthesize a Verilog design.

解决方案

To work around this issue, in the generated core's source directory edit the file with the same name as the generated coreandmake following modification. For example, if the CORE Generator default name is used, the file would be called s6_pcie_v2_3.v.

Change:

parameter [2:0] PM_CAP_AUXCURRENT= 3'd0

to

parameter PM_CAP_AUXCURRENT = 0

These warnings do not occur when using XST or Synplify with a VHDL design.

Revision History:
01/18/2012 - Updated; added reference to 45072
07/06/2011 - Initial Release

Note: "Version Found" refers to the version the problem was first discovered. The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
