Hello everyone. I tried "make drc-user_proj_example" and "make drc-user_project_wrapper". Both of them outputs same error message as below. Error parsing "/home/harada/Project/011_OpenLane/caravel_test_001/caravel/gds/drc_on_gds.tcl": couldn't read file "/home/harada/Project/011_OpenLane/caravel_test_001/caravel/gds/drc_on_gds.tcl": no such file or directory I checked the directory but there are no drc_on_gds.tcl file. How can I fix it?

@Yomei Harada Looks like the

caravel/gds/drc_on_gds.tcl

file was deleted about a year ago. You can find the file here https://github.com/efabless/caravel/blame/7067304fd9e64584f8f2148422386ae0078a0a6f/gds/drc_on_gds.tcl but it may not be supported. You can run precheck to do drc on the

*project_wrapper

level.

I got it. I use precheck to user_project_wrapper.
