Title: Error during ASSURA parasitic extraction.
Post by VINAY RAO on Feb 29^th, 2012, 10:48pm

Hello all,
I am using assura 3.1.6 USR 1 with IC 5141 hotfix and also with UMC 90nm technology. DRC (by setting some switches) and LVS ran successfully for my simple inverter layout but RCX gave the following error.
capgen Capgen results will be written to directory: /home/vinay_rao/work/test2
*ERROR* at "capgen": -blocking mask layer 'NCAPGATE_25' not defined in LVS file quitting.

I also went through the post
http://www.cadence.com/Community/forums/p/13908/22563.aspx which has noted about the same error but I didn’t find ‘resimulate_extracted’ switch set (as it is foundry dependent). And I didn’t understand clearly about Quek reply.

Can anyone suggest me how to resolve this for UMC files?
Regards,
Vinay Rao.

Hi,
Are you sure your PDK is qualified for your tool versions?
