Any Way to identify double hits (Via)?

Alice
Alice over 17 years ago

If  on the same net DRC, due to the stack via design. Alot of DRC will apply also.

Is there a way to identify this issue? Pls advice.

 Regards,

Alice

    Wouldn't it be easyer to setup drc rules to accept stacked via 's ?

    My problem is how to detect 2 same via overlap each other but has slight different xy position at same layer? These 2 vias have same net. So, if I on the same net drc, I will get alot of drcs.

    Dave,

    What would you recommend for duplicate pins? We have many designs where we need to have overlapping components for alternate population options (for example one build will use heatsink A and another build will use heatsink B and both heatsinks must be placed in the same XY location in Allegro) which mean overlapping through hole pins which we also need to "remove". So far we have modified your findDoubleHitHoles_public.il code to replace one of the duplicate pins by a "null padstack" (padstack with no drill or shapes) but was wondering if you or anyone else had a better idea on how to deal with this issue? Delete the pins? Move the pins 

    Thanks,

    Olivier
