how to calculate the total routed wire length?

archive

Hi All,

How to calculate the total length of the wire routed in a layout. It should consider all the metals used for routing and at all levels of hierarchy.  [Read in latest Spectrum magazine that the total wire length may reach from 2kms to 10kms for the latest processes and curious to find one for my teams' design also which is a very big Layout design and we are using VXL].

  • set signal_NetWirelength 0

    set signalNetWireLength [open "Avg_signal_NetWirelength" "w"]
    set signal_NetWirelengthMicrons 0.0

    dbForEachCellNet [dbgTopCell] netPtr {
    if { ![dbIsNetSpecial $netPtr]} {

    set signal_NetWirelength [expr { [dbNetWireLenX $netPtr] + [dbNetWireLenY $netPtr] + $signal_NetWirelength } ]
    set signal_NetWirelengthMicrons [dbDBUToMicrons $signal_NetWirelength]
    }
    }

    puts $signalNetWireLength "\n\nTOTAL SIGNAL NET WIRE LENGTH =$signal_NetWirelengthMicrons"
    close $signalNetWireLength
