Easy or automated way to find slivers in a Allegro database

Scot S

Hello

 I was wondering if anyone had a easier or automated way to find slivers on plane layers in a Allegro database

Thanx Scot

    No but you can modify the minimum aperture for gap width under the shape global shape parameters - void controls tab which might stop them being produced in the first place. The delete islands command will also locate all the unconnected ones....

    Scot,
     
    Allegro and most of the CAD tools are a layman tool which helps to make circuit out of copper, as compared to olden days many constraint are put in to take care of Fab house issues but are limited or still long to get there....
     
    To pin point the FAb house issues we need to use the CAM validation tools like Valor & other tools - which are particularly designed to report FAB/Assembly related issues. Valor has cross probing facilities to Allegro which zoom to location of problem but to again fix we need to edit or modify parameters manually.
     
    Good luck!!

    Well...I don't know if I'd classify Cadence or other PCB Design software as "laymans tools", but I do agree that Valor should be used to check the layout over prior to release.

    Laymans tools?
