STEPS TO FOLLOW TO DRC

1. Open your PCB layout (.brd) file from your Autodesk EAGLE Control Panel.

2. Select the DRC  tool on the left-hand side of your interface to open the DRC Setup dialog.

You’ll be using the DRC Setup Dialog whenever you need to run your DRC or change the default rule set.

1. Take a minute to check out the default rules set here in all of the available tabs. When you’re done, select the Check button to run your Design Rule Check.

2. If you have any issues to address, the DRC Errors dialog will open as shown below. And if there aren’t any errors, then you’ll see DRC: No errors in the bottom-left corner of your interface.

When we ran the DRC on our completed LED flasher project we didn’t have any errors, so we decided to intentionally make one by overlapping a trace with a component pad. When we ran our DRC check again, we had two errors for overlapping objects on layer 1, which is our top layer.

 

Every DRC error gets an accurate name and layer to help you easily identify it.
