First DRC warning
Checking the box on the dialogue form will prevent it from appearing in the future. If you left
click the mouse on the DRC section of the status bar a small window will appear providing
information on the errors. You should see that they are of type PAD-EDGE as the pads of the
crystal are closer to the keepout graphic than the 15
th
specified in the Design Rules.
Displaying DRC errors
We have two options here:
1) Ignore the DRC errors. The keepout graphic will not impact on connectivity.
2) Move the graphic to a legal distance from the pads. The easiest way to do this is to first
change the snap level down (View Menu), right click on the graphic and select the Drag Object
context menu option, and then change the snap level back when you are finished.
When you are finished your keepout area should look something like the following screenshot.
