Subject: Help!! ECO's Can't Be Re-Timed In Our Arcadia/PrimeTime Flow!
Hi John,
In our sign-off procedure we use Arcadia and PrimeTime. We use Arcadia
for RC extraction, and Primetime reads the DSPF file generated by
Arcadia for static timing analysis.
In our regular flow, the input to Arcadia are the LEF and DEF files.
When we're doing a manual ECO, the data of the ECO is in GDS2 format
only. To extract the data, we need to run LVS on the GDS2 data and then
invoke Arcadia. The output DSPF generated by Arcadia (in this case) is
in transistor level, while Primetime annotates only gate level DSPF!!!
This is a very severe limitation! The timing on the ECO nets cannot be
verified. Solutions/work-arounds will be appreciated.
