Hi, The openlane flow exits even linter and synthesis do not have any errors, but only warnings. The warnings are related to undriven but used pins. When I disable QUIT_ON_SYNTH_CHECKS the flow do no exit and continue. Is it normal that the openlane flow exits even synth and linter do no have any errors? errors.log, openlane.log and config.tcl files are attached Regards,
