Extracting All Names from Wires with Multiple Names

AB_1717543042707

Hello,


The problem I am having is that I am trying to get the names of wires on a page. I already have code to iterate over every schematic, every page, and every wire. However, when I use the GetNetName command for my wire, it only returns the top name for the wire. In my design, I have wires that have more than one name. I want to find a way to extract all of the names of each wire. Does anyone know how I can do this?

I appreciate it.

    Hi AB_1717543042707,

    You can try the below code which will give you schematic net, Alias Name and Net Name of a wire.

    Need to select the design and source the below code.

    set lNets [CapFindObjects $COrFindFilterDlg_NETS {*}]
    set lStatus [DboState]
    # set lAliasName [DboTclHelper_sMakeCString]
    # set lNetName [DboTclHelper_sMakeCString]
    # set lSchiNetName [DboTclHelper_sMakeCString]
    set lNullObj NULL
    foreach lNet $lNets {
    set lAliasName [DboTclHelper_sMakeCString]
    set lNetName [DboTclHelper_sMakeCString]
    set lSchiNetName [DboTclHelper_sMakeCString]
    set lWiresIter [$lNet NewWiresIter $lStatus]
    #get the first wire
    set lWire [$lWiresIter NextWire $lStatus]
    while {$lWire != $lNullObj} {
    puts $lWire
    $lWire GetNetName $lNetName
    $lNet GetName $lSchiNetName
    set lObjectType [$lWire GetObjectType]
    if {$lObjectType == $::DboBaseObject_WIRE_SCALAR} {


    set lAliasIter [$lWire NewAliasesIter $lStatus]
    # #get the first alias of wire
    set lAlias [$lAliasIter NextAlias $lStatus]
    while { $lAlias!=$lNullObj} {
    #placeholder: do your processing on $lAlias
    $lAlias GetName $lAliasName


    set AliasNetName [DboTclHelper_sGetConstCharPtr $lAliasName]
    set SchiNetName [DboTclHelper_sGetConstCharPtr $lSchiNetName]
    set NetName [DboTclHelper_sGetConstCharPtr $lNetName]

    #get the next alias of wire
    # puts $lAlias
    set lAlias [$lAliasIter NextAlias $lStatus]
    }

    # $lWire GetNetName $netname
    # puts [DboTclHelper_sGetConstCharPtr $netname]
    #placeholder: do your processing on Wire scalar $lWire
    }
    #get the next wire
    delete_DboWireAliasesIter $lAliasIter
    set lWire [$lWiresIter NextWire $lStatus]
    puts "AliasNetName: = $AliasNetName , SchiNetName := $SchiNetName , NetName: = $NetName"
    }

    }

    If this doesn't work for you then can you please share the screen shot of you schematic(a wire with multiple name) for what you are looking for.

    This code almost works for me. I just need help figuring out how I can get the lNets variable but by iterating through the design rather than having to select the design manually and then sourcing the code. So to clarify, instead of using set lNets [CapFindObjects SCOrFindFilterDIg-NETS {*}], I would like to iterate over the entire design, that way I do not have manually select the design in capture.

    I really appreciate your help.

    Hi AB_1717543042707,

    Good to hear that it worked for you.

    Please find the below code which need to be sourced(capture command window) without selecting the design.

    }




    }
    puts "AliasNetName: = $AliasNetName , SchiNetName := $SchiNetName , NetName: = $NetName"
    #get the next wire
    set lWire [$lWiresIter NextWire $lStatus]
