Using Skill to create a Padstack with a Thermal subclass that has geometry set to "Flash"

thewill2live

Hi all,

 Trying to pick up Skill here on my own and I'm having a bit of difficulty trying to get a specific part of my code to work. I am writing a Skill program that will be able to automatically generate a padstack based off of a naming scheme. I have most of it figured out but I cannot get the code to work for instances where I want a plated through hole pad that has a thermal subclass on the default internal layer that has a geometry of "Flash". I am attempting to set it using the ?figure parameter but that only recognizes Circle, Square, Oblong, Rectangle, Null, and Octagon as valid inputs but not Flash (even though Flash is a valid choice in that dropdown menu in the Allegro Padstack Editor. I'm using Allegro 16.6 and I've included the line in question with the section I'm speaking of bolded. Any advice is appreciated.

; This would work, but is not what I need. 

 pad_list = cons(make_axlPadStackPad(?layer "DEFAULT INTERNAL", ?type 'THERMAL, ?flash "Th391x371x92", ?figure 'OCTAGON, ?figureSize 80:80) pad_list)

 

; This won't work, but is what I'm trying to accomplish 

 pad_list = cons(make_axlPadStackPad(?layer "DEFAULT INTERNAL", ?type 'THERMAL, ?flash "Th391x371x92", ?figure 'FLASH, ?figureSize 80:80) pad_list)

 

Thanks,

  • Don't inclue the ?figure option.

    Try:

    make_axlPadStackPad(?layer "DEFAULT INTERNAL", ?type 'THERMAL, ?flash "Th391x371x92", ?figureSize 80:80)  

  • Thanks Dave,

     I tried that already and leaving out the ?figure option results in it being evaluated as nil and the padstack is made with a "Null" geometry. I actually just figured this out on Friday. Since there is no predefined option for "Flash" I couldn't use ?figure 'FLASH. But since it is really just evaluated as a string,  I found that I could pass in a string and get the desired result. So I did: 

    make_axlPadStackPad(?layer "DEFAULT INTERNAL", ?type 'THERMAL, ?flash "Th391x371x92", ?figure "FLASH", ?figureSize 391:391) pad_list 

    And that solved my problem.
