    multiple via spans

    jbarina

      New to Explorer and I need to set up more via spans in the setup parameter for my design.

      In the attached picture I have my initial setup for a set of via's and now need to also setup

      another set using same via spans (Layer to layer) but they have different size holes and or pads.

      When I setup the first via I get an warning..."invalid via span definition & via spanning layers 1 through 2

      has already been defined."

      Thanks,

      John

          John,

          You only need to setup unique via spans once in Setup Paremeters--these would have the "default" via assignments. If you have different via sizes you need to accomodate you would define their use in CES as a Net class property. So for power nets, you would create a new net class and in the Trace and Via Properties tab for this net class, change the Via Assignment for each via span to the appropriate via type.
