How to get the thickness of StackUp

archive


I can get the Etch layer name by:
axlGetParam("paramLayerGroup:ETCH")->groupMembers
But how about the thickness and the material thickness, which set in Setup Advisor>Edit Cross-section. Is it attribute or parameter?
How can I get it by SKILL command?

  • The data can be extracted from the Tech file. There is a Skill command _fpDrawGetXSection() that gives this data but it is unsupported and I would not recommend its use. I have attached a small utility to export a tech file. Read in the Tech file

  • Yeah, the command:_fpDrawGetXSection() can generate one list about XSection, it's similar with your attachment il file.
    Is it initial command of Allegro? Why not recommend and unsupported?
    Thanks, Dave.

  • Any of the functions described in Cadence product documentation (in $CDSROOT\doc\algroskill) are supported and recommended.

    There are also any number of "private" Skill functions. These cannot be recommended for use. The functionality of any of these private, internal, utilities may change at any time, as the needs of Allegro developers dictate.

  • Hi, How would you use _fpDrawGetXSection() and get the result in a text file. If you're running the lowest tier of Allegro it is not possible to run the techfile commands.

  • Hi Ole,

    You should be able to run the tech file batch commands from the low tier tool. Just register your export tech file command in your allegro.ilinit file. eg:

    axlCmdRegister("export tech" 'ExportTechFile)
    ExportTechFile.autoload = "ExportTechFile.il"

    Restart Allegro and type "export tech" on the command line.

    This is also the way you would run a Skill routine that used _fpDrawGetXSection, but I still wouldn't recommend using this command unless Cadence make it public. You would print the output of this command to a file using fprintf. The output is a list so the most simple printing method would be to use something like:

    pport = axlDMOpenFile("TEMP", "stackup.txt", "w")
    fprintf(pport, "%L", _fpDrawGetXSection())
    axlDMClose(pport)

    Cheers, Dave
