Deleting stacked micro-via

Wale

Hi All,

I have a 2-6-2 HDI board. the micro-vias are stacked (L1-L2, L2-L3 and L8-L9, L9-L10). The buried via is an staggered.

I would like to delete L1-L2 and L9-L10 micro-via (only) using a list of x,y co-ordinates of some micro-via locations. 

The problem i am having is that, my script deleted the stacked micro-vias in the x,y location . Its seeing the stacked microvias as a single via.(of course because they  re both at same coordinate location)

Can someone point me to how i can go about this? 

If there is a script out there that can do this, can someone please share.

Thanks

  • axlClearSelSet()
    axlSetFindFilter(?enabled list("noall", "vias", "invisible"), ?onButtons list("noall", "vias"))
    axlAddSelectAll()
    axlDeleteObject(setof(via, axlGetSelSet(), axlGeoPointsEqual(loc) && car(via ->startEnd) == "ETCH/TOP" && cadr(via ->startEnd) == "ETCH/L2"))
  • Hi Dave,
    thanks for the assistance. I do appreciate it.
    However, i am not comparing the location of two micro-vias before i delete which is what axlGeoPointsEqual(loc) is supposed to do. Also, axlGeopointsEqual() should accept 2 arguments instead of 1. ( i encountered this error when i ran the below script <E- *Error* axlGeoPointsEqual: too few arguments (2 expected, 1 given) - ((-42.5 -19.85))>

    Goal: to delete a micro-via from L1(TOP) to L2. or from L10(Bottom) to L9. These micro-vias are stacked with the other micro-vias from L2 to L9. so they all have same coordinate location.

    Please take a look at the script i have below ( i referenced your code above as well), any help in the direction i should take?
    The script calls a .txt file that has the location of the micro-via to delete.
