#143 Move add_route_obs before global routing Pull request opened by antonblanchard On a design with many large macros, FastRoute is placing guides right through the middle of those macros. TritonRoute never manages to recover from this and I end up with over a thousand DRC issues due to these tracks. In order to stop this I added an GLB_RT_OBS line covering all the macros, but that didn't help FastRoute because the obstructions get added after global routing. Moving add_route_obs earlier fixes this. efabless/openlane Travis CI: Build Created
