I'm getting this error while running make user_proj_example for my custom design. I assume my die area is less than what is required. I set die area 0 0 2000 2000. Can someone tell what are the coordinates to utilize all the user project area? And this error really is due to less die are or due to something else?

share openroad_issue_reproducible generated during run time from openlane
File a github issue in openlane, so it will be easy for track

I have not created any github repo yet I have just placed my verilog file in rtl folder and make some changes in config.tcl present here /home/em/mpw/caravel_user_project/openlane/user_proj_example. So what which file you want me to show you?

I believe that this can happen if the target density is chosen too high. Try something like: set ::env(PL_TARGET_DENSITY) 0.2 in config.tcl. You may also have to do something like set ::env(FP_CORE_UTIL) "27" at the same time, but I'm not sure if that's actually needed. And which values are good for your design is also not clear. If you set the target density too low, at least you seem to be getting an error message about this during the workflow.
