Changing spacing constraints when opening Allegro

Mstrghettorigg

Hi All,

 I was wondering if anyone can guide me in the right direction.

I'm trying to make it so I can set the bottom SMD pin to TH distance when allegro starts up.  This will need to be done to all files being opened.

I'm not familiar with writing skills, but I was wondering if anyone has ran into similar Skill file or at least guide me in the right direction.

I looked through some forum and it looks like I can use axlCmdRegister and axlTriggerSet commands to run the skill automatically once I have the skill file create.

I think this command is where I need to get started from, but I don't think it's that simple. 

axlCNSSetSpacing("" TOP 'Thru Pin_SMD Pin .050 INCH) 

Any help will be appreciated.

Thanks! 

  • I tried putting the text in the skill file and it came up with an error.  I tried it on allegro.ilinit file and it also gave me an error.

    I have few skill files being loaded via that allegro.ilinit file so I am assuming it is working correct. 

    I typed "1" in front of axltriggerset... and I get the message below.

    E- 1axlTriggerSet('open 'TH_SMT) 

    E-                ^

    E- SYNTAX ERROR found at line 25 column 16 of file allegro.ilinit

    E- *Error* lineread/read: syntax error encountered in input 

    Opening existing drawing... 

    Does "Opening existing drawing..." mean that axlTriggerSet is running before the board actually opens and that's why it's not working? 

    Thank you again. 

  • GOT IT!

    You need to include an arument in your function for the trigger to work. Try:

     defun( TH_SMT (t_open) axlCNSSetSpacing(nil "ETCH/BOTTOM" 'thrupin_smdpin axlMKSConvert(50 "mils"))

  • Hello Dave,

    It worked perfectly! 

    Thank you very much for your assistance! 

  • Hello Dave,

    I was wondering if you could help me with this.  I found a older thread on how to make a form by Venkata and I was not able to get the buttons to work.  I would like the OK button (Button 1) to run the code we worked on for setting the constraints of bottom SMT to TH to be 50 mils and NO button (button 2) to just close the form.  Please see below for the skill file content.

    (defun test ()

    CreateForm()

    myform=axlFormCreate( (gensym) form_file nil 'Form_Action t)

    axlFormDisplay(myform)

    axlUIWPrint(myform date)

     

    )

     

     

    (defun CreateForm ()

    drain()

    form_file = "test_form.form"

    fprintf(myform "ENDTEXT\n\n")

    fprintf(myform "ENDTILE\n\n")

    fprintf(myform "ENDFORM\n\n")

     

    close(myform)

    )

     

     

    (defun Form_Action (myform)

    (let (t1 item index field cnt)(printf "field/value %L = %L (int %L\n)" 

    myform->curField myform->curValue, myform->curValueInt )

    (printf "doneState %L\n" myform->doneState )

    case(myform->curField

    ("Button1"

     

    ;Button Field 

    ;Enter Action Here

    )

    ("Button2"

     

    ;Button Field 

    ;Enter Action Here

    )

    )

    )

     

    if((nequal myform->doneState 0)

    axlFormClose(myform))

    )

     

    It says button field 
    ;Enter action here so I'm assuming this is where I put the code in.
     
    I tried
    defun( TH_SMT (t_open) axlCNSSetSpacing(nil "ETCH/BOTTOM" 'thrupin_smdpin axlMKSConvert(50 "mils"))) and axlCNSSetSpacing(nil "ETCH/BOTTOM" 'thrupin_smdpin axlMKSConvert(50 "mils"))), but neither worked.  

    Please let me know if you are able to help.
