Question

I don’t want to use the default via when routing my design. How do I assign my own vias?

 

Solution

The vias used in a design are assigned in the physical domain of the Constraint Manager. They can be assigned in constraint sets or individual nets. The method is the same regardless of the object.  

  1. To change the via, open the desired worksheet.

     
  2. Locate the default via you want to want to re-assign in the Via column.  
  3. Double-click the cell to open the Edit Via List form. You can add and remove vias in the Via List.
    The list of available padstacks on the left can be filtered by entering characters in the “Filter by name" field as shown below.



    The order of the vias in the list is the preferred order when routing.
