    PADS Autorouter issue - routing layers exceeeded

    rahul.chander

      Hi

       

      I keep getting an error in PADS Autorouter that I have exceeded the maximum routing layer limit.  I don't understand how this is possible.  I got the following setup in layer definition:

       

      Layer 1: Top

      Layer Type: Component

      Plane Type - Split/Mixed

      Routing Direction: Any

       

      Layer 2: Power

      Layer Type: Routing (Greyed out)

      Plane Type - Split/Mixed

      Routing Direction: Any

       

      Layer 3: Ground

      Layer Type: Routing (Greyed out)

      Plane Type - Split/Mixed

      Routing Direction: Any

       

      Layer 4: Bottom

      Layer Type: Component

      Plane Type - Split/Mixed

      Routing Direction: Any

       

       

      It was able to auto-route before on the same four layer board and now I don't know what setting got changed such that it no longer works. 

       

      Any help would be great.

       

      Thanks
