How to extract over thousands of symbol's subclass with skill?

abdulhalim

Hello,

I am trying to automate a process of extracting symbol's DFA_BOUND_TOP and PLACE_BOUND_TOP using skill.

The symbol's are all located form our library's directory which can be placed on the board through Place -> Manually -> Select Advanced Settings tab to check the library box -> Select Placement List tab and select package symbols in the dropdown menu.

Steps what I would like for SKILL to be used:

  1. Open up Allegro PCB Editor (select desired product)
  2. Change the board grid size to millimeter
  3. Select Color192 (Ctrl + F5) to turn global visibility off besides DFA_BOUND_TOP and PLACE_BOUND_TOP
  4. Place symbol from library
  5. Get symbol's DFA_BOUND_TOP and PLACE_BOUND_TOP subclasses using "Show Element (F4)" with "shapes" under find option.
  6. Export the "Show Element" Box in .txt with symbol's name (ie: resistor1.txt).
  7. Repeat steps 4-6 until all the symbols from library .txt have been exported
  8. Close Allegro PCB Editor

Right now I have the process that is being done using the record macro. Unfortunately, it cannot use conditional or decision making, for example to name the file according to the symbol and implementing a for/while loop.

Any help or guidance is much appreciated.

If there's any questions please feel free to ask.

I am on 16.6.

  • If you have never done any Skill programming then you have some hard work in front of you. There is a good start with the Skill Language User Guide in the doc folder. To get the shapes you can use axlDBGetShapes("PACKAGE GEOMETRY/DFA_BOUND_TOP") and axlDBGetShapes("PACKAGE GEOMETRY/PLACE_BOUND_TOP"). For each shape you can get the extents using shpObjDBID ->bBox and simple maths to determine the x and y extents. The height is a property of the shape eg shpObjDBID ->prop ->PACKAGE_HEIGHT_MAX. Try this code for an example: foreach(shpObjDBID, axlDBGetShapes("PACKAGE GEOMETRY/PLACE_BOUND_TOP"))
    exts = shpObjDBID ->bBox
    x = caadr(exts) - caar(exts)
    y = cadadr(exts) - cadar(exts)
    height = axlMKS2UU(shpObjDBID ->prop ->PACKAGE_HEIGHT_MAX)
    sprintf(nil, "%g,%g,%g\n", x, y, height)
    )
