Short-resistor removal for LVS cleaning (Cadence Virtuoso + Pegasus)

yogeshjaiswalCAD

Greetings Team,

 

Thanks for always being there for help, I am working on TSMCN22 node, facing issue in Pegasus LVS cleaning as it not truncates shorted rupolym

Resistor (Plus & Minus) shorted

 

Cadence Virtuoso + Pegasus

Short-resistor removal for LVS cleaning

Best practice: device-level LVS filtering

 

Recommended (ONE-LINE SOLUTION)

 

lvs_filter_device rupolym -short_pins [PLUS MINUS]

 

What this does

  • Applies to Pegasus LVS + extraction
  • If a rupolym resistor has PLUS and MINUS on the same net:
    • X Device is removed from LVS
    • X Device is removed from spi
  • Layout geometry remains → DRC unaffected

This is the official Pegasus mechanism for shorted passives, When I am using above option to Pegasus- LVS run is taking lot of time (almost 15hour on IP) without above option is it will take on half hour to run.

Request : Please provide PVL code or any other advice or trick to remove shorted resistor rupolym in pegasus  LVS process 

Please suggest to me what option needs to be checked or selected in the Pegasus LVS option tab. 
I will be grateful for your help. Please help in !

With Warm Regards,

Yogesh Jaiswal
