PIN select issue

catalineacsu

Hello,


I am working on a skill that generates a report with vias in pad but I am having problems using the single select function. It selects pins that are not overlapping the via but instead are 20 mils away. When I am running running the code line by line it works fine. If anyone spots a mistake please let me know. Or a workaround better than axlSingleSelectBox, which works better but not perfect...

The logic behind it is:

1. turn on vias and pads on one side of the pcb

2. select all visible vias

3. parse the list and select the pins overlapping the center of the via

4. report the result

The code is below (please forgive minor mistakes in the code if any. I have a 99% working code implemented with axlSingleSelectBox function and the one below is recreated from memory):

    axlWindowFit()
    axlVisibleDesign(nil)
    axlVisibleLayer("PIN/TOP" t)
    axlVisibleLayer("VIA CLASS/TOP" t)
    axlUIWRedraw(nil)
    
    axlClearSelSet()
    axlSetFindFilter(?enabled '(noall VIAS) ?onButtons '(noall VIAS))
    topvias = axlGetSelSet(axlAddSelectAll())
   

    axlClearSelSet()
    axlSetFindFilter(?enabled '(noall PINS) ?onButtons '(noall PINS))
    foreach(via topvias
        axlAddSelectPoint() ; this is the line that is not working!!!
    )

    vippinlist = axlGetSelSet()
    axlClearSelSet()

  • Did you think about doing it with polygons?

    pinCuPoly = car(axlPolyFromDB(pin ?layer "ETCH/TOP"))

    axlGeoPointInShape(via ->xy, pinCuPoly)

  • Hello Dave,

    Thanks for the hint. It helped.


    It crossed my mind that a point inside a polygon could solve the problem but had absolutely no idea how to do that as I was not aware of the "GEO" functions.

    This being said, it works perfect on the boards I tested. Below the final code fragment, for reference:

    foreach(via topvias
            SelectedPin = car(axlGetSelSet(axlSingleSelectPoint(via->xy)))
            if(SelectedPin != nil then
                PinCuPoly = car(axlPolyFromDB(SelectedPin ?layer "ETCH/TOP"))
                if(axlGeoPointInShape(via ->xy, PinCuPoly) == t then
                    fprintf(Log_File "%s @ \t (%.2n %.2n )\n" via->name xCoord(via->xy) yCoord(via->xy)) ; or do anything usefull
                )
            )    
        )

    problem solved, topic closed.

    Regards,
