The –no_design_rule option is not used frequently and as the name
2 X( Z! |! J' O' T, o7 ssuggests, it instructs DC to refrain from fixing DRCs. You may use this
option for initial passes of compile, when you don’t want to waste time

then re-compile incrementally to fix DRCs. This is obviously a painful
approach and users are advised to make their own judgement.
