    Route Keepout Questions Reply

     1.  When I use Route Keepouts, I get DRC errors when there is a via within this Route Keepout.  The actual DRC is "Thru Via to Route Keepout Spacing".  Pretty much all of the time, I don't mind that there is a via in the Route Keepout, as long as there is no route connected to it.  For instance, if I have a keepout on a layer beneath traces for impedance control and the traces in question happen to via.  If I cared about vias in that area, I would add a Via Keepout too.  Is there a way to supress this DRC without waiving it for each design?  I don't want to use voids in the pours as those are prone to disappearing if one needs to delete a pour and recreate it for any reason. 

     

    2.  I use Route Keepouts to keep pours from flooding areas in which I don't want copper and not necessarily always for true route keepout.  For instance, while routing Ethernet between the transformer and the RJ45 connector, I use a Route Keepout - All to remove all pours below these routes.  However, sometimes, it is necessary to route other traces from the RJ45 or through this keepout area.  For this application, I am really using the Route Keepout as a Pour Keepout and not the traditional "keep all routes out".  This creates many DRC errors for the routes that need to go through these areas.  Is there a way to supress these DRC errors withouth waiving them for each design, or perhaps, better yet, a better way to do this?  Again, I don't want to use voids in the pours as those are prone to disappearing if one needs to delete a pour and recreate it for any reason.  I wish they had something like a Pour Keepout.  That would be nice.

     

    Thanks.

    Set the colours to get the Route Keepout plainly displayed, left-click on the Route Keepout Shape, check the Find Filter / Super Filter allows this, then, having picked the Route Keepout, right-click>Property Edit, you can set Routes Allowed, Shapes Allowed and Vias Allowed in any combination, as required to allow the objects you need within the Route Keepout.

     It was just that easy.  Very clear directions too.  You're my hero.  Thank you very much oldmouldy.
