Error during ASSURA parasitic extraction.

RAO VINAY
 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 filequitting.

*WARNING* Bad return status from RCX script generator. 0x100

I also went through the post http://www.cadence.com/forums/p/13908/22563.aspx which has got 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 Vinay Rao

    To put it simply, the Assura LVS extract.rul file which you are using is out-of-sync with the contents of the QRC tech directory. There might have been some layer changes which are not reflected in the QRC setup files. You can download the latest version of the pdk and retry. If it still results in error, you will need to report this to the foundry. : )
