how to get gate count in synopsys

Hi
How to calculate gate count in synopsys. Is there need to map to any library to check the gate count

thanks in advance

nand2 smic

you must synthesis with a library first.
after synthesis, you wouldn't get gate count exactly in synopsys, just an evaluation value.
use 'cell_areas/nand2(nor2)_area', all of them can get from report.

Hi,
Dont you get this in the map report.

Re: gate count

Hi Hi... I dun think that you will get gate count using synopsys dc compiler, but only area size.... but u able to get transistor count if u want.. check with specification given by the fab house, they state the transistor count for the gates. later develop a perl program to count the amount of transistor from gate level netlist

Re: gate count

Usually, NAND2 gate is used to calculate the gate count of a design.

Exp,in smic library,1 NAND2 = 9.98 um*um. So if your area report from DC is N um*um, then your gate count is about N/10.
