MIG 3.61 Spartan-3A DDR2 - MIG 3.61 failed to generate core in Coregen 14.6


MIG 3.61 fails to generate a core in Coregen 14.6 or 14.7 when I do the following:

  1. Regenerate the MIG core in batch mode by using xco and prj files generated from Coregen 14.1.

  2. Generate a design, then select Bank 3 for the Data/Control Group and bank 2 for the System Clock.


This issue is caused by a format change for the MIG version.

To work around this issue, ensure that the MIG version in the xco file is MIG 3.61, not MIG 3.6.1.

Then run Coregen -ddd to generate the core in batch mode.
