Utility to output a single symbol from a design

joma

jm_write_1_symbol_public.zip

Hi, I recently discovered the skill command "axlWritePackageFile( car(axlSelectByName("SYMTYPE" symbol-name))->definition )" which writes a single footprint
from a pcb. The good thing about it is it writes the symbol .dra and.psm files with all associated padstack files. I find this very handy from time to time. The bad thing
is it is a pain to be typing skill commands like this so I have created a user interface form to make things easier. As I have benefited from lots of utilities found in this
forum I thought I would contribute something of my own (however simple).

To load the code type "skill load("jm_write_1_symbol_public.il"). The file shoud be in your skill path.
To run the code type "write one symbol" on the command line.

All feedback welcome.

Load the Skill code using"skill load("RotateSilkAssyRD.il)" - See more at: community.cadence.com/.../17911

  • A simple example for a string form:

    p = nil
    sprintf(p "FILE_TYPE=FORM_DEFN VERSION=2\tFORM\tFIXED\tPORT 50 10\tHEADER \"TITLE_OF_FORM\"\tTILE")
    sprintf(p "%s\tTEXT \"HELLO\" \tTLOC 2 1\t\tENDTEXT" p)
    sprintf(p "%s\tENDTILE\tENDFORM" p)
    defvar(fw_test nil)
    axlFormCreate( 'fw_test list("test_form" list(p)) '("CENTER" ) 'fw_callback t)
    axlFormDisplay(fw_test)

    basically you need to make 1 long string that contains the form. New lines need to be \t (tab), not \n or \r.
    Then you need to call axlFormCreate with this : list("test_form" list(p)) the "test_form" can be any string you like.
    The rest of the form function, creation, handling etc is equal to the file-based form.

    To return multiple variables you can or return a list like list( result_a result_b) and then use car() and cadr() to extract the results returned from the function
    Another way is to use a global.
    First you need to generate a global with defvar() and then at the end use var_name = 'unbind. The last statement unbinds/removes the global variable.
    Don't put this global variable into the let(), otherwise it won't work.

    A hint, you can use the form variable to store return values like;
    axlFormCreate( 'fw_test ....
    fw_test->test = "hello"

    and then you can recall the value by simply using 'fw_test->test'.
    Since in the above example the fw_test is a global, you can access it anywhere in your functions.
