Silicon Ensemble + Report RC

[suresh]

Hi,

I have a routed design (using silicon ensemble) to begin with to which
I make modifications like adding additional logic (nets and components)
afterwhich I place the design all over again and re-route. Is it
possible to estimate congestion - in view of new nets being added? Is
it possible to get capacitance information - using the dspf files that
are written out? What do I look for either in a .dspf or .rspf file?

How do i use the HyperExtract option while doing report RC - will that
help?

I currently have def and dspf file of design before modification and
def and dspf file of design after modification.

Any help would be appreciated.

Thanks,
Suresh
