Tom Spyrou, I'm wondering if you are also interested in cases where the tools are not working and trying to figure out why. I spent a considerable amount of time designing a chip, but was unable to submit it because the OpenROAD tools kept crashing. I tried many dozens of various settings trying to get to a GDSII, but each resulted in tool issues. I don't know if this was something wrong with my design (it synthesizes just fine with Cadence RTL compiler and Yosys) or something with my environment (Ubuntu 18.04 working with the downloaded Docker image). I'm certainly interested in continuing to try if I can find a way to get the tools to work properly for me. They clearly work for others seeing all of the designs that were completed.
