DRC Problem after updating trace width - now won't go away

Justin Loop
Justin Loop over 5 years ago

I have an interesting problem.  I have eight (8) connectors on a PCB. One, for some reason, is giving me problems.  I am getting a DRC problem.  I have NO IDEA why I am getting this problem.  Here is some picture for a better understanding:

I have no idea how to fix this problem.  Please provide a STEP BY STEP resolution to fix this.  All other connectors are just fine.

Thank you.

    Try to identify what is meant by [ Textline"1" ] . Try to run Tools > Database Check and Tools > Update DRC. Verify in the Constraint manager if there may be a specific directive for N21360 or parent group.

    On version 17.2, I am not seeing Tools > Database Check or Tools > Update DRC. Here are some more screen shots:

    So just to be clear, I have 8 of these connector, and this is the only one (the other seven seem fine) experiencing problems.  The problem started when I increase the width of the trace.  All connectors have the same sized trace now. I can't get this problem to go away no matter what I do!  Thanks in advance for your help!

    Sorry, not familiar with 17.2 menu structure but my gut feeling tells me perhaps you may want to try killing this cline and create a 50% narrower one  just to check how the app react. Check the Constraint manager directives also. In my 16.6 I can get access to the Constraint manager with Setup>Constraints>Constraint Manager.  Check into Spacing Domain>Net workbook> All Layers> Line. You may have a peculiar directive related to line spacing directive. Check if all your nets have the same directives.

    Hello,

    It looks like you have a text string ("1") sitting inside of the pad boundary on the Bottom Etch Layer which is causing the DRCs.

    Using Check > Element (Show Element) with only Text enabled in the Find pane and you should find the text string on Etch/Bottom.

    If you do find it than simply delete it to remove the DRCs using similar steps

    1. Edit > Delete
    2. Enable only Text under the Find pane
    3. Select the text string "1"
    4. RMB > Done

    Hope this helps,
    Mike Catrambone

    One better way to find out what this error is...use Tools - DRC browser which lists the type of DRC. If it is related to constraint then you can vary the value to get rid of it
