Detailed routing failed: Signal 6 received Stack trace

[Asma-Mohsin]

Description

The tool crashed at the detailed routing step with the stack trace shown in the log.

The project that was run can be found here: Asma-Mohsin/FPGA_IGNITE_2024@e468a53

Did we possibly do anything wrong or is this a bug? If we did anything wrong, would it be possible to catch this as an error?

If any further information is required, please tell.

Expected Behavior

Succeed detailed routing or get an error message.

Environment report

How is this done when using the Caravel setup?

@Asma-Mohsin Hello. I have a couple of questions:

• When I tried the provided commit, I had to make modifications to the configuration file. I disable linting because if failed and I have to include additional verilog files. Are you sure you are providing the correct commit for the repo?
• Which OpenLane version are you running? Even after the modifications mentioned above I faced different issues during synthesis and never got past it.
