Using the Xilinx/Mentor interface I am running pld_edif2tim on my design.edn that has come from the xilinx tool (ngd2edif), and I get the following error in the transcript window:
// Note: Reading EDIF file "/home/testcase/top.edn" (from: Synthesis/EDIF Interface/Command Interface 85) // Error: Unable to resolve reference "my_bus_7_0_" of type "portRef". (from: Synthesis/EDIF Interface/System 04) // Error: Can NOT create a design. Was NOT able to read the edif file successfully. (from: Synthesis/EDIF Interface/Command Interface 1C)
I have an EDIF macro in my top level schematic design, for which the EDIF was created using Synplicity.
What can I do to get around this to do a timing simulation?

Currently the only way to get around this is to de-select the simulation option "correlate simulation data to input design" which will NOT use the NGM file in NGDAnno. The drawback to this is you will not be able to cross-probe back to the original design.
