    How to assign VIA to a net name? Reply

    Hello,

    I'm having problems with adding/naming Vias. I select the "Add via", then "by geometry", specify it's geometry and put (click) it over an existing net. The problem however is, that the Via isn't connected to the net. The attribute window says it's net is _NULL.

    I acquired the property value with:

    >dbGet selected.net.name

    and it returned _NULL as expected, however the counterpart command

    >dbSet selected.net.name desired_name

    returned "Attribute 'name' of object 'net' does not have set permission .....", which makes sense, sinse the attribute window didn't allow the change either. 

    The question therefore is how to tell a VIA that it belongs to a particular net, apart by crossing nets orthogonally?

     

    regards

    You can select the via then run "editChangeNet -to netName" to assign it to the desired net.

    I tried using vias on GND as an example

    my entry was: editSelectVia -nets GND

    The response from the system was: 

    E - Command not found: editSelectVia -nets GND

     

    Though I would be making progress if I could get that to work, I don't really want to change every single via of a net to a new net, just want to be able to select some vias (through whatever method) and assign them a net name.

    this method is only to select all the vias of a net, so it may not be what you want. however, i'm concerned that you got "command not found". it's like your encounter session is in some weird mode or something... can you post a screen shot of the command window maybe?

    Thanks again for working with me on this :)

     Screenshot shows post command entry response and my cursor hovering over a via on the net GND

     You're right though, in most cases I wont want to change very single via of a certain net, but my hope is once I figure this out, I can select vias with a different method and still apply the net change to them just the same. One step at a time...

    Well, that solves the problem. You are using a tool other than EDI (Encounter Digital Implementation) System. I don't know what tool that is. We may need to send your question to a different forum. :-)

    Ahh, yes I found the thread and didn't realize that "DI" was not appropriate. Since I am using Cadence PCB Editor 16.6, and this is a PCB Editor question I assumed it would be relevant - definitely my mistake! So there are more than 1 PCB layout tools by Cadence? Sheesh!

    EDI is not for PCB layout. It's for IC floorplanning/place&route/timing-closure/etc... I'll move your question to the PCB forum.

    I had trouble splitting the whole thread out - please check the PCB Design forum and make sure your question looks ok there. If not, please re-post there. Thanks!

    I already had posted it as a new question, just the snippet you moved for me is a bit incomplete. I really appreciate the guidance though, and I apologize for my ignorance of the various Cadence tools / threads. I know it's important to keep things organized to get the best help, I will aim to do better in the future.
    Cheers Raylon

    No problem! It's kind of funny how the question can apply to both tools. :-) Sorry I didn't catch it sooner....
