Problem of RC Extraction with GPDK45nm(gpdk045_V_3_5)

JB786

Hi

When I was running RCX extraction using ASSURA with gpdk045 model. Always I'm getting warnings and then failed to extract layout. From the log file, some libraries models are missing in gpdk45.

Please see below log file.

 

Thank you

    Two things:

    1. You should use Quantus QRC not Assura RCX (QRC is in the EXT stream). Assura RCX is very old and no longer maintained
    2. The missing ivpcell for g45cmim was fixed in gpdk045 version 4.0 (you're using 3.5). You should be able to workaround this by unchecking the "Enable cellview check" checkbox on the QRC form (or Assura RCX form) - this will not then complain if any of the devices seem to be missing.

    Andrew.
