Hi,
Anyone knows how can i analyze IR drop & EM with Encounter?

Thanks!
 

Hi

early power analysis
before your are going ran IR drop and EM in vstrom tool from cadence
1..In you design where the std.cells are placed close to each other or logic is placed only one side of core area,it causes IR drop issue
2..where you have seen long net ,it causes EM migration issue

after ran the IR drop and EM

where you have seen red hotspot in core area,it's seems IR drop in that area...
where you have seen more congestion in core area..,it causes IR drop





Regards
chiranjeevi
