How to make a iteration of all the VIAs in SOC Encounter database?

archive

Hi, all:

I am Roc Sun. Recently, I got a few problems.

One is how can I iterate all the via instances in SoC Encounter. I can find the command 'dbViaCellName' or something, but I can not find the way to get via instances. As you know, in SoC52, it 'split via' utility is not working. So, I want write my own version using database command.

The other is that, how can I get all the drc box coordinates, I mean the white boxes after we made a DRC check in SOC Encounter. I want to write this script in db commands.

Best Regard!

    Bob:

    Following is my script,

    proc getNetRoute { netName } {
    set FILE [open net_physical.rpt w]
    set netPtr [dbGetNetByName $netName]
    set iter [dbIterRoutes $netPtr]
    set routePtr ""
    while { [set routePtr [dbRouteNext $iter]] != "0x0" } {
    set type [dbObjType $routePtr]
    if { $type == "dbcObjWire" } {
    puts $FILE "Wire found:"
    puts $FILE "[dbInfoWire $routePtr]"
    } elseif { $type == "dbcObjStripBox" } {
    if { [dbIsStripBoxVia $routePtr] || [dbIsStripBoxViaCell $routePtr] } {
    puts "via $routePtr found"
    dbHiliteObj $routePtr 4
    # dbHiliteObjBox $routePtr
    dbSelectObj $routePtr
    }
    puts $FILE "Wire/Via found:"
    puts $FILE "[dbInfoStripBox $routePtr]"
    puts $FILE "Z: [dbStripBoxZ $routePtr]"
    dbSelectObj $routePtr
    set netPtr [dbStripBoxStrip $routePtr]
    set objType [dbObjType $netPtr]
    if { $objType == "dbcObjNet" } {
    puts "[dbNetName $netPtr]"
    } elseif { $objType == "dbcObjSNet" } {
    puts "[dbSNetName $netPtr]"
    } else {
    }
    } elseif { $type == "dbcObjVia" } {
    puts $FILE "Via found:"
    puts $FILE "[dbInfoVia $routePtr]"
    } else {
    puts "Error found, unknown type $type"
    }
    }
    dbEndIterRoutes $iter
    close $FILE
    }

    The only way I found to get the 'vias' is using the above 'dbIterRoute' method. And it seems that SOCE now only support stripbox for all the routes (including wires and vias). We cannot get the via instances.

    For your method to select vias 1st, It also ends up with getting 'dbcObjStripBox'. I will post another question in a new thread.
