Getting the Height of a Symbol

schang412
schang412 over 4 years ago

Hello,

How can I get the height of a symbol in Cadence SIP Allegro using SKILL. The number is present when I click [Show Element] then click on the symbol, but I can't figure out how to access it programmatically. I need to dump all the component heights out to a file. 

 

Thank you,

Spencer

    Hi Spencer!

    I found this in document, hope can help you.

    Example:

    data = axlGetDieData("FLIPCHIP_1")
    printf("stack-pos = %L, layer-name = %L, attach-type = %L\n"
    data->stackPosition data->layerName data->attachType)

    axlGetDieData (g_dieId)
    ==> die-data defstruct/nil

    defstruct fields:
    dbid dbid of die
    refId die refdes
    memberType DSA_DIE
    stackName parent die-stack name
    stackPosition integer position of member in stack
    layerNamedie pad layer
    dieThickness die thickness (flipchip bumps not included)
    totalThickness die thickness (flipchip bumps included)
    stackHeightMin starting height within stack
    stackHeightMax ending height within stack

    origin die symbol x/y location
    rotation rotation angle in degrees
    extents unioned extents of all members in stack
    type one of DSA_DIE_STANDARD or DSA_DIE_CODESIGN
    attachType one of DSA_DIE_FLIPCHIP or DSA_DIE_WIREBOND
    orientation one of DSA_DIE_CHIPUP or DSA_DIE_CHIPDOWN
    bumpDiamAtPkg flipchip bump diameter at package
    bumpDiamAtDie flipchip bump diameter at die
    bumpDiamMax flipchip bump diameter maximum
    bumpHeight flipchip bump height
    bumpEcond flipchip electrical conductivity w/units

    Hi Luan,

    Thanks, this looks very close to what I want. The only thing is, I am trying to get the thickness of the capacitors, so they are marked as discrete. I think I can just change the component class, get the value, then change it back as a workaround, since I don't see a similar function for discretes.
