klim

在set_driving_cell後都會加-no_design_rule
請問加了有什麼好處?

The –no_design_rule option is not used frequently and as the name
suggests, it instructs DC to refrain from fixing DRCs. You may use this
* s* @/ W) G; X  [( |5 uoption for initial passes of compile, when you don’t want to waste time
fixing DRC violations. At a later stage, generate the constraint report and
then re-compile incrementally to fix DRCs. This is obviously a painful
approach and users are advised to make their own judgement.
