If we comment the

set ::env(GLB_RESIZER_TIMING_OPTIMIZATIONS) 0

variable, it crashes at step 15- resizer_timing with the following message:

INFO GRT-0101] Running extra iterations to remove overflow.

[INFO GRT-0103] Extra Run for hard benchmark.

We suppose that both errors are related. Any suggestion?

Try to view your layout and see where its congested. sharing test case will help us to reproduce and resolve it

How can I see the layout? Because the gds to load at klayout it is only generated at the end of the flow or not?

check cts.def

Hi, I opened with Klayout, but I don't know what I have to search. Everything looks identical
