Hi, I have been trying to harden one of my designs submitted in mpw1 shuttle, but I am unable to harden the same for mpw3, using the configurations as used before for mpw1. I am continuously getting overlap issue at detailed placement, in spite of using different values of FP_CORE_UTIL and PL_TARGET_DENSITY. Is there any other parameter apart from these two that might help solve the overlap issue?

Try commenting

set ::env(PL_BASIC_PLACEMENT) 1

. But overlaps usually require to low more density. At least in my case
