How to get the cellviews hierachy

wenckey

In Virtuoso, if I have the target cell name "target", top cell name "top", lib name "mylib", view name "layout". How can I get the hierachy path for the "target" from "top"?

Like hierachy path: top->cellA->cellB->target

    Hi wenckey,

    Code below will get all the instance hierarchy path from top level.

    Hope it helps.

    ;procedure(CCFgetInstanceNamesAndCoords(master @optional (transform list(0:0 "R0" 1)) (hierInstPath "/"))
    procedure(ci()
    cvId=geGetWindowCellView()
    csh("touch ./instance_coord.txt")
    outPort = outfile("./instance_coord.txt")
    fprintf(outPort "\n Coordinates of instances of %s with a library %s :\n\n" cvId~>cellName cvId~>libName)
    ctr = 0

    procedure(CCFgetInstanceNamesAndCoords(master @optional (transform list(0:0 "R0" 1)) (hierInstPath "/"))


    foreach(inst master~>instances
    when(inst~>objType=="inst"
    ctr = ctr +1

    printf("%s%s %L\n" hierInstPath inst~>cellName dbTransformPoint(inst~>xy transform))
    fprintf(outPort " %d. %s%s %L\n" ctr hierInstPath inst~>cellName dbTransformPoint(inst~>xy transform))


    CCFgetInstanceNamesAndCoords(

    inst~>master

    dbConcatTransform(inst~>transform transform)

    strcat(hierInstPath inst~>cellName "/")

    )

    ) ;when


    )

    t


    )


    CCFgetInstanceNamesAndCoords(cvId)


    fprintf(outPort " \n\n\n <<<------------------------------------------>>>" )

    fprintf(outPort " \n\n End of instances coordinates list . " )

    fprintf(outPort " \n\n <<<------------------------------------------>>>" )

    close( outPort)
    ;view("./netConnection_layout.txt" list(0:0 500:500) "SCHEMATIC NET CONNECTION")
    ; edit("./netConnection_layout.txt")
    ;hiRegTimer("system("open_net_selected")" 100)
    sleep(3)
    system("gedit ./instance_coord.txt &")

    ; End of outport


    );proc

    Best regards,

    Marben
