My design is crashing in route:

Any ideas what could be the problem... maybe Total Wirelengh shouldn't be negative?

Thanks
Do I also need to update PDK? I now get [INFO]: Running Static Timing Analysis... OpenSTA 2.2.0 0d73b5b65a Copyright (c) 2019, Parallax Software, Inc.

I wouldn't suggest checking out to a random commit of develop. Either use master, or latest develop but always assume that develop might not be stable. @Jean: how big is your design? Does it have any macros inside it?

If it says "Killed", you need more RAM
Change the way you're starting the docker container

The box has 24GB of RAM. Is it a docker limit?

Yeah, there's a RAM limit in the container start configuration
