Subject: User Asks What's The Deal With The New PhysOpt 2.5 D Extraction?

Hi John,

I'm wondering if anybody knows what's the deal with the new 2.5 D extraction
engine in PhysOpt.  Specifically, will it eliminate the RC correlation step
in PhysOpt? 

I was told by the PhysOpt R&D manager at DAC that this new extraction engine 
should eliminate the need for correlation.  That we should try it for
ourselves and if the R and C factors are not close to 1, we should file a
bug report.  However, our scaling factors turn out exactly the same as their
1-D extraction and nowhere close to 1.

I can't get a straight answer from Synsopys.  Any ideas?
