RC Physical Flow - Spare Module

Yemelya over 9 years ago

Hi,

This is a copy of my question originally posted at the Digital Implementation forum.

http://community.cadence.com/cadence_technology_forums/f/29/t/34626

I am trying to convert the conventional RC-Encounter flow to RC-Physical.

Since the placement is loaded through the DEF file generated by RC-Physical script, there is no more need to run "placeDesign" or "place_opt_design" commands; and "placeSpareModule" instruction in Encounter runs immediately and spreads randomly all the spare cells across the placed floorplan, without localizing them in spare modules, as it was done by the "old fashion" flow.

Is there a way to keep Spare Modules placement for RC-Physical flow as it was done for the RC conventional flow (spare modules distributed evenly, but spare cells inside the modules are localized)?

Thanks and regards,
- Boris

You can look at enc_* attributes but not sure there is much value in doing it in one over the other. Possibly biasing placement if very extensive use
