I’m getting a

tritonRoute

error immediately after

start track assignment

but there isn’t much extra context from the logs. I’ll link in a reply the

config.tcl

used in my project repo for reference incase there are any obvious errors. Have others seen this on openlane

develop

? https://gist.github.com/dan-rodrigues/ea8cc9395707267a527332918a6dedc6

config.tcl I'm using: https://github.com/dan-rodrigues/caravel/blob/vdp-lite/openlane/vdp_lite_user_proj/config.tcl Any obvious issues to call out? I've only recently starting trying to replace user_proj_example with my own work

I've had several crash that appear / disappear depending on the placement result.

right that's interesting..wonder if it's invalid placement further up the flow that could cause it

Copy code

Warning: Overlap check failed (115).

This warning (but not a hard error) looks concering but don't know if it should be..

ATM I have yet to get a successful run on a non-example design.

For the more complex designs you've tried, if you get past that triton crash, does it just crash on something else? Or you run into that SRAM placement issue in your screenshots?

I got everything from placement fail, outright crash/segfault, fatal errors, final drc errors, ....
