  • Could you please detail your question:
    Are you dealing with a hierarchical design ?
    Your overlap Layer represent rectilinear partition ?

    To print the cutout rectangle for a partition (before commit) you can try the following script:

    set instancePtnName "You partition instance name"
    set ptnCut [dbGetPtnCutByName $instancePtnName]
    while {$ptnCut != "0x0"} {
    if {[dbPtnCutName $ptnCut] == $instancePtnName} {
    set ptnCutBox [dbPtnCutBox $ptnCut]
    puts $ptnCutBox
    }
    set ptnCut [dbPtnCutNextInFPlan $ptnCut]
    }
