Help - Diva DRC / ChagedLayer

    Every time I run Diva DRC on a cell, I have to do an
    Edit Cellview Properties - Property and delete
    drcSigniture and drcChecked to prevent changedLayer
    from being added to the layout when I make edits.

    How do I prevent the changedLayer function from
    turning onn when I run Diva, until I want to use it?

    Thanks,

    Joe

    Hi Joe,

    Creation of the changedLayer is dependent on:

    a) drcSignature/drcChecked properties on the cellView (created by a Diva DRC
    run)
    b) the contributesToChangedLayer property on a layer being enabled in the tech
    file - changes to that layer cause the changedLayer to be modified.

    If you never want the changedLayer to be created, turn this property off for
    all layers. Since it is only needed if you're going to be doing incremental DRC,
    you only need it enabled for that purpose.

    Andrew.
