Enable Multi corner analysis

Open vijayank88 opened this issue 1 year ago • 3 comments

Description

Has read_liberty already having variable CORNERS with https://github.com/The-OpenROAD-Project/OpenROAD-flow-scripts/blob/master/flow/scripts/read_liberty.tcl , is possible to update the flow to run for multi corner at a same time?

I tried to use export CORNERS = "BC WC" but still flow taking default setup from platform config.mk.

Then found, in platform variable used is CORNER and flow script it is used as CORNERS.

So which one is correct?

I have changed name to CORNER and flow failed during the creation of merged.lib itself for asap7 platform.

Is there WIP in this enablement?
