please confirm your Assura-RCX version is compatible with the tech file.

The techfile requires av4.1, and assura i used is version4.1. So the version is match.
I have no problem at LVS, so I think assura version is not a problem. Do you know other reason for this error?

Thanks for your attention.

Please try QRC for the extraction instead of Assura-RCX.

This "auto_comb" feature in the process file is a QRC option that is not supported in Assura RCX.

what's your exact meaning? I'm junior of IC design and not familiar with the assura tool or calibre.
Can you explain the details and tell me how I should do with your rely "use QRC instead of assura-RCX"?

Thanks very much!

QRC is next generation of extraction tool from Cadence. You can use QRC after Assura LVS. Please download software EXT and install it.
