    Keepouts Reply

    I have a connector symbol that has two mounting holes. I want to have an area around the mounting holes where there can be no other components. On the bottom side there shall be no traces, but traces are allowed on the top side.

    I have tried many different keepouts and the only errors I ever get are for vias or traces inside the keepout area. I can put a component in there and don't get any error.

    I have tried:place outline, Route Keepout, Package keepout, all will allow me to place a part within the keepout area.

    Suggestions?

    Tom

     Tom - your concept of the usage is correct.  I suspect you've already experimented with top/bottom/all with the placement/keepout boundaries?  If so, it sounds like the check has been disabled.

    Go into Constraint Manager, click on Analyze, Analysis Modes, Design Modes (Package) and see if everything is on.

    I checked the settings you suggested in CM and they are all on except the height one, which I'm not concened with. After spending over an hour trying to get this to work, I'm moving on. I'll use the soldermask around the hole as a visual indicator to me to keep things out of that area.

    Thanks,

     IF you don't mind sending a PM with the files attached or zip them up and post them on the forum I would be glad to look at the issue.

    Thanks for the offer, but NDA in place with customer so can't send any board files.

    Those options were not checked. When I checked them, some drc's came up around the part in question. I'll have to go back into the symbol editor and make some adjustments to the keep out areas. I know what I have on the board will work, I just need to understand what the drc's are telling me. I'm sure it has to do with something I did when making the symbol and trying to get it to have the keep outs I was looking for.

    I won't get to it until later today.............

    Thanks,

    Tom
