Creating a multiple drill padstack in SKILL with custom pattern

Brother Forage

I'm trying to figure out how to create (custom) multiple drill in SKILL.

my kung-fu of searching help files and forums may be weak but all i find is referring to 17.2 or older versions.

using

padID=axlLoadPadstack("myPadWithPolarDrillPattern")

padID->??

to see if it can bring some light in the matter doesn't help either as no matter the (custom) drill pattern made on padstack editor, the drill reported is

multiDrillData   (1 1 0.0 0.0 nil)

Can I make a list of drills in the same manner as a pad list and submit as drill data?

I am using revision 17.4 S32 as IT policies prohibits me from install latest versions or hotfixes.

    I'm unclear on where you are getting stuck. Creating a padstack involves quite a few steps. However, the key step for creating a multidrill padstack is adding ?multiDrillData to the make_axlPadStackDrill command: Something like this:

    make_axlPadStackDrill(?drillDiameter drillDiameter, ?figure figure, ?figureSize figureSize ?plating "PLATED" ?drillChar drillChar ?multiDrillData list(x y 0.00))

    I hope this helps

    I try to be clear, but fail to explain what I want to do.

    With multidrilldata in make_axlPadstackDrill it is possible to define a grid of x * y holes with x and y clearance. rectangle=yes, rhombus=yes, triangle=no.

    If I want a drill pattern of a pentagon, or looking like the big dipper (for whatever reason) it can be done in the padstack editor with polar or custom drill patterns, but I fail to understand how to do it in skill.

    In short, all that can be done in the padstack editor, I want to do in skill.

    Thanks for explaining. I can't see a solution. Cadence hasn't documented this and I can't see a work-around. I think you need to raise an enhancement request. Let us know how you get on.
