Voltus 20 getting stuck during DEF import

Dracarris

Hey there,

I have a design that I can import without any problems into Voltus 14,16, and 18. However, during the defIn phase in Voltus 20, the tool simply gets stuck with full CPU utilization and never continues. More specifically, this happens at the point of the DEF import where the other versions start resolving the instantiated cells by using the lef libraries given to the tool earlier.

There is absolutely no debug information available from Voltus, so has anyone ever solved this issue before or can point me a possible problematic parts of the def that I should have a look at?

Thanks a lot in advance.
