power pins of stdcells

chitlesh

Hi there,

Is there a way to get the power pin names of a particular placed stdcell within EDI?

  • Hi

    You can try the following procedure to get the power/ground name(s) of a given instance.

    Usage : findPGTerms -inst <instance_name> -termType <power | ground>

    ################################################################################
    # Procedure to find a list of Power/Ground pins of all cells in the design
    # Usage : findPGTerms -inst <instance_name> -termType <power | ground>
    ################################################################################
    proc findPGTerms {args} {

    # Get instance name
    if {[regexp {\-inst} $args]} {
    set instName [lindex $args [expr [lsearch $args -inst] + 1]]
    }

    # Get term type
    if {[regexp {\-termType} $args]} {
    set termType [lindex $args [expr [lsearch $args -termType] + 1]]
    }

    # Help
    set helpString "Usage : findPGTerms \
    \-inst <instance_name> \
    \-termType <power | ground> \
    \-help"


    if {[regexp {\-help} $args] || $args == ""} {
    puts $helpString
    return 0
    }


    # Main code
    ############################################################

    # Get inst/cell pointer
    if {[dbGet top.insts.name $instName] == "0x0"} {

    puts "\nERROR: Instance $instName not found!\n"
    return 0

    } else {

    set instPtr [dbGetInstByName $instName]
    set cellPtr [dbInstCell $instPtr]

    set allPGTerms {}

    dbForAllCellPGFTerm $cellPtr termPtr {

    if {${termType} == "power"} {

    if {[dbFTermType $termPtr] == "dbcPowerTerm"} {
    set powerTerm [dbFTermName $termPtr]
    lappend allPGTerms $powerTerm
    }
    } elseif {${termType} == "ground"} {

    if {[dbFTermType $termPtr] == "dbcGroundTerm"} {
    set groundTerm [dbFTermName $termPtr]
    lappend allPGTerms $groundTerm
    }
    }
    }
    }

    set PGTerms [lsort -unique $allPGTerms]

    return $PGTerms
    }
