Change NetName

honey1

I want to change/replace the NetName in the capture design through TCL Script. So far i've been able to change the PinNames of any particular part and the names of OffPageConnectors of whole pages. I am getting the PinName and its corresponding NetName through $lPin. What I actually want to do is to add the PinName to its corresponding NetName with an underscore "_" between them. The Net Name is not being changed but if I try to change/replace the PinName which include the (NetName_PinName) it just works fine.

 

Please give me respective suggestions.

    I don't think that you have appreciated the way that the net name works. The name for a DboWire is assigned by Capture, N<some sequence number> is assigned and that is the Name of the Wire in the Capture DSN data, this can be overridden with a Net Alias, for example; more strictly a "higher order object": Net Alias, or Off-Page Connector, or Hierarchical Port. If the "higher order object(s)" are removed the net will revert to the original, Capture assigned, name. Since you have changed the Port name, the net name in the generated netlist will adopt that, or the highest level the net is named.

    As an aside, if you are doing this for the whole design, how is Net<something> / Pin<somthing else> ever going to connect through the design? Since it seems unlikely that a net of a given name is always going to be connected to a pin of the same number.
