Crash with buffer_fanout #3

Closed kareefardi closed 4 years ago

kareefardi commented 4 years ago

Hello,

I was trying out buffer_fanout. After executing it using optimize_fanout -buffer_cell <cell> -max_fanout <fanout>. It outputs [2019-12-16 08:44:26.345] [info] High fanout nets [4390]: , followed by a crash (segmentation violation). This is the sequence of commands that I used:

import_lef
import_def
import_lib
link_design
set_wire_rc
optimize_fanout

Is there anything missing?

Can you provide the test files if they can be published (or in private if you prefer)? Or at least the core dump and the tool logs? It is a bit hard to replicate with only the sequence of command (given that there is a similar working sequence here: https://github.com/The-OpenROAD-Project/OpenPhySyn/blob/master/tests/tcl/buffer_transform.tcl)

Closed for now. Until I have time to investigate further. Thank you
