@User If the synth_ecplorer result is something like this, how can i choose the optimal configuration for the config file. and Could you please guide is it possible to set die area using this area value shown in table?

Sorry I don't know enough here to advise

thanks @User Could you please suggest me how to choose proper die area based on some parameter if possible?

I would let the tools choose the size

may i know what config i should choose to make the tool decide. if i didn't mention die_area or target density in config file is it choose proper area and density?

Set the density and not the size. Check the spm example
