And another question. When I want to create a LEF to use as a template in magic for pin placement, how do I define the pnr boundary? Is that possible?

The PNR boundary is defined by

property FIXED_BBOX _llx lly urx ury_

where

llx lly urx ury

are given in magic's internal units (that is, put the box where you want for the boundary, and use the

box

command to get the values and plug them in).

Thanks, @Tim Edwards. Adding to my cheatsheet
