    Hi


    I there any way to detect dangling metals in layout using a script?
    Or it can be detected using any CAD tools like Hercules/Assura etc?


    Thanks

    Dear Manjunath,

    Are you looking for the dummy/tiles metals that are used for density
    filling ?
    It's very hard to check this with a simple script because you've to
    check the connectivity of each piece of metal.

    If it is for density purpose, many foundries use a Layer purpose which
    is not the standard 'drawing' intended for normal layout drawing/
    routing. I've seen metalX.dummy, metalX.tile ...
    Dedicated Verification CAD tools support this feature, so don't waste
    your time in reinenting the wheel ...

    Hope it helps ...
