Can we add the FILLER cells after routing completed

archive

Dear all,

I am working on Place & Route flow,

1. can any one suggest me when we should add FILLER cells ie after completing routing using nanoroute in cadence or after FIX wire in magma.

2. what are the advantage and disadvantages, if FILLER cells are added before and after routing.

Thanks & Regards,
Prashant
