https://github.com/The-OpenROAD-Project/OpenLane/issues/879 Workaround: Set the die area to something bigger

but i tried editing the pitch value that is causing the error in the config.tcl file , shouldn't that resolve the problem?

You can't just make the pitch arbitrarily small

okay,it did work after making slight changes in die area.
