I have found some more information. It appears that the .lib format is the Synopsys liberty library format. I found a guide on edaboard that gives a simple tutorial for characterizing a simple inverter. However, I am still no closer to finding out how to characterize a larger cell.
I am looking at an example from the memory compiler the foundry gave us. I believe I understand how the timing characteristics are generated. The most confusing thing for me now is how the power characterization is performed. How can I get power information on a per-pin basis? The memory compiler-generated file has power information on the clock pin for three cases:
cen = chip enable
wen = write enable (these are active-low signals
1. !cen & !wen
2. !cen & wen
3. cen
Why is there power when the chip enable is off? Is this leakage?
