Unconnected copper

archive

Is there a way to prevent Allegro V16.01 with "Performance Option L" from generating unconnected copper shapes when I create a copper pour area around circuitry ? Do I have to place many "Route Keepout" areas ? Any help would be appreciated.

    You could delete unconnected shapes by using "Island_delete" command. Putting of many Route keep out areas will take lots of your time.

    Thanks very much for your reply. I'm new to Allegro and never had the opportunity to use that command.

    When you're creating the "pour areas" (adding shapes), make sure you use the "Assign Net" function after you've drawn the shape you require. If you don't assign it, it will be a dummy net. Should be easy for you.

    Good day.

    Another thing to look at is the void control, "suppress shapes less than" box.  Bump up the minimum size and you will eliminate a bunch of tiny islands.  Otherwise  Island Delete works or change your constraints.
