I have a design on a Virtex-4 FX device with the MGT protector IP. When compiling the models for simulation, the compiler errors out because of port mismatches in the MGT. Why does this happen?
For designs with MGTs, the system timing model contains extra ports that do not exist in the MHS. The test bench generated by SimGen does not define these extra ports. When compiling the models for simulation, the compiler errors out as a result of port mismatches.
To work around this issue, remove the MGT Protector from design when using it for simulation purposes. The MGT protector IP is a very simple IP created to take care of the NBTI issue. The IP is required only in hardware.
