How can I detect the duplicated vias? I tried to identify duplicate vias from the DRC errors, but duplicate vias don't seem to be included in the DRC warnings.
Duplicate vias are reported in the DBDoctor report rather than the DRC report. The steps that follow describe how you can identify and remove duplicate vias.
- With your design open select Check > Database Check.
- Check the desired check boxes in the DBDoctor form that control the scope of the DRC check.
- Click the Check button.
- If there are redundant vias they are reported in the log and the duplicates are removed.
