    Microvia/burriedvia creation issue in PADS layout

    faizan.ul-haq

      Hi,

       

       

      I need to make microvias from layers 1-2 and 3-4, also a burried via between layer 2 and 3. How can i do this thing in PADS layout. I read the help documentation and made a 'Drill pairs'  as follows (See also screenshot attached).

       

       

      Four layer board (TOP, PWR, GNDA,BOTTOM)

       

      Drill pairs setting:

      Starting layer      Ending layer     

      Top                    PWR

      PWR                 gnda

      gnda                 bottom

       

      Then i defined the partial microvias in setup>padstack>via from layer 1-2 and 3-4. (See screeshot attached).

       

      Now after all these settings, when i try to route a signal and generate a via, following error starts appearing, and no via is generated.

       

      STANDARD - L1 - Via is not  defined on level specified

       

       

      Can somebody expalin this.
