How to Extract segment length info from Constraint Information in SKILL

Ahmed0ms

Hello, 

Is there a function to extract the info in the blue circles (pin/via locations and cline segment length and layer) in SKILL?

Thanks

    The information you are requesting is available directly from Allegro, the skill access to data in Constraint Manager is extremely limited IMHO

    Below is some example skill code that will report the net data in a format somewhat like the data in blue:

    procedure((Report_nets)
    let((units accur net)
    (axlSetFindFilter ?enabled list("noall" "nets") ?onButtons list("noall" "nets"))
    (units = car((axlDBGetDesignUnits)))
    (accur = sprintf(accur "%%.%df" cadr((axlDBGetDesignUnits))))
    (mypopup = axlUIPopupDefine( nil (list (list "Done" 'axlFinishEnterFun) (list "Cancel" 'axlCancelEnterFun))))
    axlUIPopupSet( mypopup)
    while((axlSelect ?prompt "Select a net...")
    (net = car(axlGetSelSet()))
    when(net
    foreach(branch (net->branches)
    foreach(child (branch->children)
    if(((child->objType) == "pin") then
    axlMsgPut(" (%f:%f) pin %s.%s %s %s" xCoord(child->xy) yCoord(child->xy) child->component->name child->number car(child->startEnd) cadr(child->startEnd))
    )
    if(((child->objType) == "via") then
    axlMsgPut(" (%f:%f) via %s %s %s" xCoord(child->xy) yCoord(child->xy) child->name car(child->startEnd) cadr(child->startEnd))
    )
    if(((child->objType) == "path") then
    axlMsgPut("%f %s cline %s" axlDBGetLength(child) units child->layer)
    )
    )
    )
    )
    )
    )
    )
    axlCmdRegister("report_nets" 'Report_nets)

    Below is the Allegro transcript from running this skill code:

    Command > report_nets
