Any help would be great.

This error is often seen when the hard macros are placed too close to an edge or too close together. Try centering the macro or adding more room between macros.

Do I set the parameters in

dependencies/openlane_src/configuration/placement.tcl

?

you can change the macro placement in

openlane/user_project_wrapper/macro.cfg

I successed through changing

config.json

"PL_TARGET_DENSITY": 0.42,
	 "FP_CORE_UTIL": 40,
