Altium design secret 20: Manage design intent with specific NoERCs

Altium Designer's Electrical Rule Checker is a powerful tool for ensuring that designs meet high logical connectivity standards, before being passed to layout. But, since these rules are all set at the project level, they apply globally to all connections within that project.

If there's a specific net to exempt from these rules, you can simply place the No-ERC marker on that net - kind of useful, but by default this causes the entire set of rules to be ignored for that net. In reality, most of the time you really just want one or two rules to be ignored, not the entire set.

In a recent update to AD, the company introduced the No-ERC manager, along with enhanced No-ERC markers. Now, when you place the No-ERC marker you can select the specific error you want to suppress, so other errors won't slip under the radar. This video shows you how.
