#1004 Design reports after routing show technically-true, but practically-useless, utilization numbers Issue created by tdene Description During the implementation of any design, OpenLane will create a

reports

folder. This

reports

folder has, among others, an area report. The area report displays both raw area, as well as % utilization. All routing and post-routing reports show 95%+ utilization due to the presence of filler cells. This is technically true, but practically useless. Environment
