Openlane is crashing for me at the [INFO]: current step index: 11. The one that executes or_opendp. It doesn't provide any error information at 11-opendp.log or flow_summar.log. I have monitored ram consumption with a script and it is far away of the maximum ram of my system. How can I know the error to know what I have to change?
v
detailed placement got struck due to overlaps. Try reduce FP_CORE_UTIL and increase PL_DENSITY
if still facing issue raise GitHub issue with RTL and config.tcl

Hi, thanks for the suggestion. Playing with both variables we managed to pass that step of openlane. Now I'm facing another issues without any error message
By the way, I'm curious. What is the meaning and the purpose of the FP_CORE_UTIL. At the documentation says The core utilization percentage, but I don't know what it means with that
v
Core utilization points how much area used for cell placement and leave remaining for routing stage.

ok, thank you
