An issue I am facing in the routing stage. Any idea on how to resolve this.?

open a GH issue with a test case. Its hard to know why a crash happens just from the log

@Matt Liberty I am actually running openfasoc which uses openroad for the pnr. The openfasoc doesn’t have any issue reproducible like in openlane to make a test case.

Still, any files that you can provide which are used to run OpenROAD are useful. For example, the source DEF file and the command script.

This is my pre_global_route.tcl. My routing is working without the above error if i just remove this tcl script from the flow. So there must be something wrong in this that is causing the error.

@vinay the dbIterm_connect is causing error as you can see in the first screen shot.

I am getting the same error even if I don't comment it

Can you share create_routable_power_net.tcl and create_custom_connections.tcl

Most likely somebody is passing invalid data to iterm_connect. I have no way to know if that is true and if so why.
