In a PCB design, I have about 30 DRC errors that cannot be corrected due to the nature of the design (overlapping parts). These DRCs are listed in the results tab and the DRC tab of the spreadsheet view.
On the DRC tab of the spreadsheet view, If I right-click the DRC list and select add to filter, the DRCs disappear from the list, and the DRC markers disappear from the workspace. - Cool. I then switch to the results tab of the spreadsheet view, right click and clear the results list. Then I run the DRC and netlist check. Still no DRC markers in the workspace, no DRCs listed in the DRC tab of the spreadsheet view, no DRCs listed in the results tab of the spreadsheet view. Just a note about filtered DRCs.
I right click on the DRC list box in the spreadsheet view and select filter manager. Filter manager appears and the filter I just created is shown. I close the filter manager, then I save all and close UB.
I start UB again and open the same project and electronic design, the DRC markers show again in the workspace. However, the DRC errors are not listed in the DRC tab of the spreadsheet view. Even if I run a DRC and netlist check. However, the DRCs are listed in the results tab of the spreadsheet view. If I right click in the results list, I cannot filter the DRCs. If I right click in the DRC list I can select add to filter, but nothing happens. If I open the filter manager, no filter is shown. If I use the task bar to switch to another program, then switch back, that's when the DRC error re appear in the DRC list.
What's with this coo-coo behavior, and why doesn't the filter manager save my DRC filters?
Thanks
