Question for anyone trying to integrate their user project in a similar way to how it’s done here: https://github.com/efabless/caravel/blob/master/openlane/user_project_wrapper/config.tcl What sort of runtime are you seeing? The runtime I’ve got so far is about the same as it took to create the GDS that is being placed here, mainly around detailed routing. Wasn’t expecting that as it feels like it’s repeating work that was done to create the user project GDS in the first place. Expected or a config problem? Was hoping this would reduce time considering I don’t need all the die area of the user_project_wrapper, which greatly increases runtime / RAM requirement
