Hi,
How to calculate power consumtion by doing Gate Level Simulation after P&R.
I want to Use tools like Modelsim..
Is there any option in Modelsim like code coverage..

Hi
Power consumption can not be accurately estimated during Gate Level Simulation and please understand that after PAR, the simulation performed will be called as Timing Simulation. Any how to estimate the power consumption, you need to know the probability of switching activity which is very difficult with the test vectors what we apply. Generally power consumption can be roughly estimated by counting the switching activity during the simulation and counting the transistors after synthesis. If you want accurate estimation then you have to use power analysis tool like voltage storm from cadence.
All the best

Besides, PrimePower can do very accurate Gate-level power analysis.
PowerCompiler can do power analysis and power optimization for both RTL and Gate-level.
The swiching activites can be in VCD or saif format.

just dump out vcd or fsdb files from your gate level simulation. I prefer fsdb files since they are very compact rather than vcd files which can be very much larger.
Use power theater tool frm Sequence designs using vcd or fsdb files, and get the power numbers, per instance in your design
