    High current GND and Power

    macbahi

      Hi!

       

      I am new using eagle.  Please I will use this schematic for High current

      Please how cant separate ground and VCC

      global  wire for VCC is haigh current  but Vcc from pin connector as example A12 is smaller so Current VCC global is the some of current Vcc at every Pin A12, A11......A1.

      in width rules net class I want to give Vcc global as examples 345Mil but every Vcc A12...A1 as example 65Mil.

       

      Its idem for GND.  It wiill be de same two width rules net class

       

      I hope you understand what I mean

          Hi Hamid,

           

          From what I think you're asking for, I don't think you can do that, at least on older EAGLE versions. I don't know about recent versions.

          You can set the rule to (say) a high value, but as a result where the trace has to be smaller you will get an design rule error occur, and you can manually approve each such exception. There are other workarounds like fake shorting components to change net rule but I don't think that's necessary here.

            Hi Hamid,

            as far as I understand you, your Power-VCC is the same as the "normal"

            VCC (the GND as well) and you only want different width for it. In Eagle

            same name is the same thing. That means you need to give one of them a

            different name, lets say VCC_PWR /VCC_GND. When you are finished with

            your design you may connect both vcc together and accept the ERC error.

            This tip goes for Eagle Ver. 7.

            Please always tell your Eagle Version so people can give you precise help.
