A Design Rule Check (DRC) checks your design for violations and identifies problem-areas with schematic error markers. The DRC report lists all objects checked and the rule violations detected.
This walk-through demonstrates how to view and correct design rule violations. After you complete this topic, you will be able to:
To follow along with this tutorial, continue with your design from Capture Walk-through 8 or use the included design file, CAPTURE TUTORIAL 9_DRC.DSN under the ‘materials’ tab.Open in New Window
Note: This New feature in 17.4 reports real-time warning violations. Enabling you to correct errors while you design. Like the other windows in the Capture workspace, the Online DRC window can be either floating or docked. Cross probe between the violation and the schematic by double clicking a line item.
Note: If you have a hierarchical design, select Occurrences for this setting.
Note: Here you can select which electrical and physical rules to check in the design. Custom rules can also be assigned.
Note: Here you can select which electrical and physical items are included in the report.
Note: This matrix is used to test connections between pins, hierarchical blocks, and hierarchical ports.
The ERC Matrix flags invalid pin-to-pin function connections found within the design. The Matrix shows all possible pin-to-pin combinations. Define a pin combination by toggling between valid (empty) or invalid (flagged with an error or warning).
Note: Here you can define rules you want excluded from the DRC by selecting the Add New button.
Note: Double click on a warning to be brought to the location in the schematic.
Note: To waive a DRC, right click on a marker and select Waive DRC. To remove all markers, Select PCB > Design Rule Check from the menu. In the Options tab, select Delete DRC Markers for Action or Do not create DRC Markers for Warning. Select Run to update the schematic.
