generating Xnet from netlist or inside constraint manager

liviovalerio

Hi to all,

i need to create some Xnet inside my pcb but the 2 nets (or more) are divided Not from a capacitor or resistor but with an IC.

so ask: is there is a possibility to generate these Xnets from a description in the Netlist or adding some attributes in the nets, or adding them directly on some way inside the Constraint Manager?

any reply will be appreciated.

have a good day to all.

Livio

    You could use an ESPICE model to define the Pin Pair that will act like a pass-thru on the IC, the same way it is done with a Discrete component

    1. Analyze > Model Assignment
    2. Select the IC on the canvas and select the Create Model button
    3. Select "Create ESpiceDevice model" and Click OK
    4. Define the pass-thru pin number sets (From   To   From   To)
      • A value of 1  10  8  15 will create pass-thru between pins 1 and 10 and 8 and 15 to form XNets
