Proving that a given netlist A results in better layout than netlist B

asinghct
Hi, I have a very general question, I have two netlists A & B, basically same functionality but somewhat different synthesis( though mapping to same library) in front end. I need to see which one of them is doing better in terms of layout. What parameters can I use to compare two layouts from soc encounter. Thanks Amit

  •  It may depend what your goals are. You can compare things like area, timing closure, power, std cell utilization, routing congestion, etc. If your goal is the lowest power, you may not care if it's harder to close timing. If quick timing closure is the goal, you may not care if you use a lot of area or power.
