Version Found: MIG 7 Series v2.3 Rev2

Version Resolved: See (Xilinx Answer 54025)

The below error is seen with Vivado simulator when simulating a MIG example design (with a modified MEM_BITS parameter value of 26 in the ddr3_model_parameters.vh file) on a Red Hat Linux machine.

FATAL_ERROR: Vivado Simulator kernel has discovered an exceptional condition from which it cannot recover. Process will terminate. For technical support on this issue, please open a Web Case with this project attached at

The same design hangs when run on a Windows 7 machine.


This is a known issue with Vivado Simulator.

Until this is fixed, QuestaSim can be used as a work-around.
