Assura QRC extraction problem

Potamus


I am currently using Assura320 with EXT71 with IBM 90nm PDK. The extracted transistor has correct length but width is always the default pcell parameter of the PDK. Is this a design kit problem? or am i doing something wrong? All passive elements are extracted correctly.

  • I am experiencing exactly the same problem. Apparently it has nothing to do with the PDK since I am having the same extraction problem for several design kits (AMS350, UMC 180nm and UMC130nm). The same problem does not appear when runing the extraction with DIVA, but I have some limitations for DIVA usage under UMC design environments. I have also verified that this problem does not appeared in previous versions of Assura (at least 3 generations ago, the first Assura Linux distribution), where the extraction process included the steps of av_extracted and av_analog_extracted generation. Can someone give a hint on how to solve this problem?
