Objects selected in schematic, but car(selectedSet()) returns Nil

jasons

I'm trying to write a SKILL script to take the selected pins belonging to an instance placed into a schematic and create corresponding pins at the schematic level.  Sounds straightforward, right?  But after selecting a couple of these things in the schematic, I try to use the old standby css() or car(selectedSet()), but then I get a return value of Nil.  I haven't found any way to access these things.  When I do an "edit properties" in the schematic editor, I see the property name "instance pins", but then can't use the "select by property" setting the property to "instance pins" to select the objects.  When I use schHiSelectAll, and then in the pop-up window select only "pin" under the category "Instance Objects", these objects finally do get selected -- but again, css() returns Nil, and thus I can find no way to work with them in my script.  Any thoughts or help would be greatly appreciated.

  • I believe those "dots" around an instance in a schematic are actually markers - markers that are child objects of the instance...inst~>children returns them. However clicking on them hilights but doesn't select them...I don't know whether there's any way to do that in a schematic editor - I'am not a schematic editor specialist though. You could select them in SKILL of course:

    (geSelectFigs (setof child inst~>children child~>objType=="marker"))

    I have used the setof function because I'am not sure whether an instance may have any other kind of (non marker) child objects

    The pin related information can be found in the marker's msg attribute.
