what is the difference between clock period defined at line:5 and line:39 ? can we change the clock period defined at line:39 since we are getting an setup violation at 24ns but not at 36ns ?

Line 5 overridden by variable

CLOCK_PERIOD

consecutive line. For sky130 pdk its 10ns, gf180 pdk its 24ns. Based on PDK selection update

CLOCK_PERIOD

value

Actually I'm facing an error of setup violation at 24ns so I tried with 36ns where I didn't face setup violation so can I do this changes?? And will it affect my MPW-precheck?

no

So how to get rid of setup violation in this scenario? Thankyou for quick response

Check each stage STA timing log and analyse it

Okk sir
