TYPES OF ERRORS

 

When you run an ERC for the first time, you’ll be presented with several error categories, including:

Consistency Errors:  This error means that something isn’t right between your schematic and PCB layout, and your changes likely aren’t in sync between both files. If you get one of these errors, consider it a major red flag to compare both versions of your design before moving ahead.

Errors:  Errors are the red stoplights. You need to step on the breaks and check these out before proceeding. Errors can be pretty significant, like having an unconnected pin that will throw your whole circuit out of whack.

Warnings:  Warnings are the yellow stoplights. While these types of errors might not mess up your design if you move forward without fixing them, it’s good practice to slow down and review them one by one. These guys are minor compared to Errors, and n include many non-design breaking issues like missing net values.
