How to assign external DRC ?

Uri Chaplin

I created a custom DRC checker and used  axlDBCreateExternalDRC.
 System DRC information includes 2 elements

but when I create external DRC with this parameters :

axlDBCreateExternalDRC( "VIAS problem", second_item->xy, drc_layer, second_item, via->xy, problem)

 I see only 1 element twice. You can see that in this place there exist 2 different vias ( TH and BL) but in report only one.


What needs change in parameters to get information about 2 elements?

    Is this better?

    axlDBCreateExternalDRC( "VIAS problem", second_item->xy, drc_layer, list(via, second_item), via->xy, problem)

    Hi Uri,

    I'm not aware of any method to shorten the dialog contents. This might be a request for Cadence.
