Do you know how to allow specific nets inside a route keepout?

John T

Sometimes we may need to allow a specific net, such as ground, inside a route keepout. No other nets should be allowed.

How do we achieve?

One answer is assigning the Route Keepout shape to an RKO Group.

 

Do this using the right mouse button over a route keepout shape, and choose “Assign To Keepout Group”.

Now enter a new group name.

This group membership is now seen displaying a show element report of the keepout. 

 

To add the nets to this RKO Group:

  • Choose the menu Edit > Groups.

Alternatively, type “groupedit” in the Command window.

  • Select the group type from the dropdown: “RKO Group”.

 

  • In the Options panel, choose the group name you want to add objects to.
  • In the PCB Canvas, now select the nets you want to add to the group.
  • Choose Done from the pop-up menu.

DRCs will now be eliminated for elements that are part of this group.

 

If there are any questions, please do add them to the comments section below.

    Hi John

    The other method is to use the CM to add the nets to the group & that works good too. In looking at this the only question that comes to mind is how would a user looking at the UI even know the method of adding the nets existed. ?. By way of a suggestion, I think it would be good if the Group Box had some way to convey that. Something like a check box or text to indicate the operation.

    One nice feature probably less obvious is that if  a user goes back to the Group box later on & chooses their RKO Group Name, the nets that are part of the group highlight so they can see at a glance what nets are in the group. That's pretty handy.

    Best Regards.
