Hey, After installing the whole pdk and openlane I've tried the examples such as SPM and the whole flow worked flawlessly; however, when I tried some other designs, as a small MAC, I've got some errors while doing the "detailed placement". Those were surpassed by tweaking FP_CORE_UTIL and PL_TARGET_DENSITY variables. My question is: I've seen that the standard designs (that come with openlane, e.g., SPM) don't have those variables defined on their config.tcl, so, does openlane need more effort while doing smaller designs? Cheers

check the last couple of lines in the config.tcl, you'll see it includes a cell library specific file that sets those parameters
