@yrrapt, @Fredy Solis and I are trying to integrate an analog opamp to caravel. We place our layout desing into the user_project_wrapper_empty.mag (we are using magic), and then we try to generate the gds file but magic crashes. It is not a problem of our layout, bacause we can generte it own gds. It is a problem with the .mag files in the develop branch of caravel. Did you succesfully generate a gds?
