    In simulation or schematic (validation)?
    For simulation I guess you would need a special Gnd connection (at least that is in LTSpice).

    It also mentions it here: https://www.altium.com/documentation...mulation-guide
    However, it does not mention how to do it...

    How do you have Gnd? Netlabel, port(s) or power port?

      In simulation in validation is no error
      What is the difference between simulation and schematic validation?

        I have never seen an error like this. What do you run to get this error (where do you click)?

          Simulation need a Gnd. That is the 'zero' volt net.
          Problem is, I cannot find how to place it.
          However, if I check simulate on my schematic, about the only issues I get are missing and some wrong models.


          What if you place a Gnd power port to one of your Gnd nets?

              Do you have a voltage source?
              Like VSRC or Battery?
