Encounter and Prime Time

[praneethrajkanakam]

Hi

I did my PNR using encounter and generated DEF file. Can someone tell me what are the other outputs should I need from my encounter to do my STA using PrimeTime.

As far I know .lib(standard cell library) file and .v (Gate level verilog netlist) file are needed for my primetime. But I have .lib from standard cell characterization and gate level netlist form synthesis.

So ,according to this without PNR we can perform STA using PrimeTime. I want to perform STA for my Design which was performed using Encounter.

So, what output should I generate from encounter , so that I can feed it to PrimeTime to do my STA.

STA can be run on 2 occasions : pre-layout & post-layout.
Pre-layout STA requires the post synthesis netlist & constraints. Post-layout requires the P&R netlist, the constraints & the SPEF file generated from a tool like STAR RC.

If you have a "gate level netlist form synthesis", then you must be doing pre-layout STA. You don't need anything else.
