Hi Shahid,

Could you send your model, so we can reproduce the error?

Best wishes,

Dave

Got it. I think the model is simply too large, I'm afraid (the tool is
not always able to catch this and report the memout error cleanly). For
me, this happens with your model even when increasing the CUDD memory.
There are a few tips for reducing model size here:
