MIG 7 Series - DDR3 Custom part simulation may fail with Undefined variable: TDQSCK_DLLDIS


Version Found: MIG 7 Series v2.4

Version Resolved: See (Xilinx Answer 54025)

The MIG example design fails with the following error when simulation is run for a custom part. No errors are seen when the MIG IP is generated with available parts from the memory part dropdown list.

** Error: ../../..mig_7series_1_example.srcs/sim_1/imports/sim/ (vlog-2730) Undefined variable: 'TDQSCK_DLLDIS'.

This error can happen when any of the parameters in the custom part wizard are modified to make a customized memory part.


This is a known with custom part simulation.

As a work-around, comment out the definition of TDQSCK_DLLDIS in, and delete its references.
