I'm having a similar issue when using nanoRoute. When I dump my technology file, the via definitions appear to be there. Additionally, when I place the design I can see that the tool is able to drop in the correct vias. I've tried creating a non default route spec, but even if I assign all nets to that NDR the tool still fails on error NRDB-158 during routing. Ideas on how to fix this?![]()
