    Routing Problems with Analog Hardware Mux

    stefan.wilke

      Hallo,

         

      I want to design a project, where a reference is brought out on P0[0] with VDAC buffered by Opamp.

         

      At the same time I want to measure the P0[0] with ADC_DelSig over AGL[4].

         

      Please look at the attached project for full understanding.

         

      The project works fine for Analog Mux but with the Analog HW Mux I get the following Error Message:

         

      "Signal "\Opamp_1:Net_29\" is expected to connect to only one GPIO analog pin but instead it connects to "\Opamp_1:ABuf\". Please fix the connection."

         

      (Please do not care about ADC_DelSig sampling or AMux switching, this is done later.

         

      Only concentrate on the routing problem!)

         

       

         

      regards Willi
