Cadence CIS:WARNING(ORPSIM-15220): Error in opening Alias File

Dear Sir:

I faced an issue with Cadence CIS during simulation. 

It note as "WARNING(ORPSIM-15220): Error in opening Alias File" if I use hierarchical block. But everything is OK if I just copy the circuit in main circuit.

May you help to find the root cause?

(I know how to use hierarchical circuit, and other circuits I built with hierarchical blocks are OK. )


And some time, I will face "WARNING(ORNET-1123): Occurrence-specific properties". But the simulation can run well. I just courious what happened. 

So much thanks for your kind help in advance!

Hi MQ,

Its hard to pin point as to why that might be happening just by the error message. If you could post the schematic, it may give a better idea in both cases
