Retrieve Flat Net Wire Properties using TCL

dk631

Using the script example in section 3.2.20 of the OrCAD Capture TCL/TK Extensions Application Notes I was able to pull the net names. To get the other information I need (user properties, port information, page location of port, etc.) I have tried using the DboFlatNetNetsIter and DboFlatNetWiresIter to get the DboNet and DboWire classes which I would then use to get the other information (I have been able to get all the information via iterating through schematic > pages > wires). However, when I call the NextWire or NextNet my script crashes OrCAD. The classes instances calling these methods are not null.

 (continued from 3.2.20 after $lFlatNet GetName $lName)

set lFlatNetWiresIter [$lFlatNet NewWiresIter $lStatus]
# check lFlatNetWiresIter and lFlatNet for null
set lFlatNetWire [$lFlatNetWiresIter NextWire $lStatus]

 Has anyone had success using the DboFlatNetWiresIter_NextWire or DboFlatNetNetsIter_NextWire?

 

 

  • I think that you have assumed that the $lFlatNetWiresIter is not null and used it to "set lFlatNetWire...", you likely need a check for if($lFlatNetWiresIter != $lNullObj) or some such to make sure that you have a valid object reference for the FlatNetWiresIter before using it.
