Design Rule Errors
NI Ultiboard User Manual
Design rule errors appear in the DRC tab of the Spreadsheet View as they
occur, and disappear as they are corrected.
Double-click on an error in the DRC tab to zoom in on the affected area on
the design, which will be indicated with a red circle, as shown in the
example below.
Depending on what you are doing on the board, you may see the following
kinds of errors if you keep the DRC tab open while you work:
•
Part "[refdes]"(value) has an unknown shape (shape name)—The
given part has a shape defined that does not exist in the database.
•
Part "[refdes]" is Not On the design—The part with the given refdes
was specified in the netlist but is not present on the design.
