In my design , prime has dumped some timing reports. I want to read this reports in IcCompiler and look into the isue ( i.e how the cells are placed) .How to do it.Is there any command to load external timing reports
Yes, birdy123 is right. You can not load such report. But, there is such ICC command as signoff_opt. It takes your design and runs star-rc (for RC extraction) and PrimeTime (directly from ICC session). Then, it loaded ptime results and trying to optimize design based on star-rc+ptime results.
