Segmentation Fault During Elaboration with ModelSim SE


If you run the ld or elab commands in the msim_setup.tcl script for a UniPHY-based IP core in ModelSim SE, you may encounter a segmentation fault during elaboration.

This issue applies to all UniPHY-based external memory interface IP cores when using ModelSim SE; this behaviour does not occur with ModelSim AE.


The workaround for this issue is to use the ld_debug or elab_debug commands as provided in the msim_setup.tcl script, or to add the -novopt option to the vsim command in the script.
