Hi! I'm a researcher in the field of VLSI testing and diagnosis (mostly gate-level and lower) and pretty exited to learn about this FOSS PDK. I tried the openLANE flow with the included example design, but TritonRoute segfaults on me. Right before that are a couple of "Error: pin does not have access point" messages. I'm not quite sure whether its a PDK or a flow issue. There were also a couple of error messages from magic while executing the open_pdk scripts, but they went through. I'd appreciate any hints on how to debug this.
