    parameter settings in Artwork Control form - Cadence Allegro Reply

    7/12/2006 8:19 AM Quote Reply  
    Hello experts,

    Anybody knows how the function axlfcreate() which takes the list of 13 numbers works?
    I want to control the 'offset x' and 'offset y' but I notice that numbers are based on design units. I couldn't find too much details on this function over cdsdoc.

    Any help?

    Saad.

    I believe this is what you are looking for:

    Example axlfcreate SKILL Command:
    (axlfcreate "film_name" '(0 0 0 8000000 0 1 0 0 0 0 0 0 0) '("VIA CLASS CLASS/TOP" ))

    Field description after film record name:
    Field 1 = Rotation (0=0 2=90 4=180 6=270)
    Field 2 = X Offset
    Field 3 = Y Offset
    Field 4 = Underfined Line Width (without decimal point)
    Field 5 = Shape Bounding Box
    Field 6 = Plot Mode (1=Positive 0=Negative)
    Field 7 = Film Mirrored (0=Unchecked 1=Checked)
    Field 8 = Full Contact Thermal-Reliefs (0=Unchecked 1=Checked)
    Field 9 = Suppress Unconnected Pads (0=Unchecked 1=Checked)
    Field 10 = Draw Missing Pad Apertures (0=Unchecked 1=Checked)
    Field 11 = Use Aperture Rotation (0=Unchecked 1=Checked)
    Field 12 = Suppress Shape Fill (0=Checked 1=Unchecked)
    Field 13 = Vector Based Pad Behavior (0=Unchecked 1=Checked)

    Hope this helps,

    Hi Mike,

    Thanks a lot for the details. Do you know what is the relation of units and accuracy settings with field 2,3 & 4?

    for mm board I have to multiply field 4 with following decimals:
    accuracy 1 => field2 x 10 , field3 x 10
    accuracy 2 => field2 x 100 , field3 x 100 and field4 x 10
    accuracy 3 => field2 x 1000 , field3 x 1000 and field4 x 100
    accuracy 4 => field2 x 10000 , field3 x 10000 and field4 x 1000

    and for mils I receive fixnum errors (when i convert mm to mils) and seems like values are only taken in mm.
    What I see here is that there is no chance to setup the parameter option specially for field 2 and 3 in mils because the resultant field values exceed the field limits.

    Thanks,
    Saad.

    correction:

    > "for mm board I have to multiply field 4 with following decimals:"

    for a mm board I have to multiply fields with following decimals

    RE: parameter settings in Artwork Control form - Cadence Allegro Reply

    here is an artwork automatic film generator according to stackup using views. It analyses etch layers and create a form with films to be created. Some are made in background (those always to be done) and other have to be selected or not.

    It includes a DBunits analyse to define Undefined Line Width according to database units.

    Hope it helps (it is made with our way of work...

    Hi Wllbi,

    Thanks for the reference code. Actually we also have a similer artwork add-on in our environment but recently somebody found a bug (it puts false decimal places when design in mils)

    I wanted to know how you handle this situation in mils?
    I see you are also multiplying with factor of 10, 100, ... for different accuracies but what about if the board is in mils?

    Regards,
    Saad.

    Sadd,

    As far as fields 2, 3 and 4 are units and accuracy are driven by the database it is loaded into.

    Here is an example of the defined fields with the database units set to mils at 3 place accuracy:

    Field 2 = -1000000
    Field 3 = -1000000
    Field 4 = 8000

    The results of the fields above would be:
    Field 2 = -1000.000 mils
    Field 3 = -1000.000 mils
    Field 4 = 8.000 mils

    Basically, all you would need to do is drop the decimal point from the resulting values and define the fields in axlfcreate.

    Here is an example of the defined fields with the database units set to MM at 3 place accuracy:

    Field 2 = -25400
    Field 3 = -25400
    Field 4 = 203

    The results of the fields above would be:
    Field 2 = -25.400 mils
    Field 3 = -25.400 mils
    Field 4 = 0.203 mils

    Basically, all you would need to do is drop the decimal point and the leading zero from the resulting values and define the fields in axlfcreate.
