To access design rules, click the design rule icon on the right toolbar. You will be presented with a list of design rule violations. You can click on a violation to locate it, or choose to ignore the specific violation if it is not applicable.
By clicking the customize button on the DRC list, you can toggle each rule.
Our new DRC features should make it easier to find issues with your design before you send it off for fabrication. You can try out the new features on Upverter.com right now!
