Thanks to @User's script, I can make sure no cells are scattered on top of my macros. but

detailed_placement_or

still fails with the vague

Warning: detailed placement failed on

There are no obvious macro overlaps anymore:

I'm independently trying to harden the remaining cells as a macro, but that has its own problems.

try

detailed_placement

instead of

detailed_placement_or

(or in addition to, calling it before)

@tnt how big are the designs you've managed to have placed nicely? this one is 20,000 instances and the tools really cannot cope

@aryap what command did you use for random placement?

aryap

11/28/2020, 5:52 AM

random_global_placement iirc

aryap

yeah you can enable it with

set ::env(PL_RANDOM_GLB_PLACEMENT)  1

if you don't run interactively

i actually don't recommend it. i'm guessing that my routing step crash is because of the random placement

My design is ~ 11k cells after synthesis.
