    Hi

    I am having trouble emulating a bus with registers using Logisim software

    I wondered if anyone has had similar issue and managed to solve it.

    I have some buffer registers:

    I have tried to connect these to the Bus using two different methods, but I get the same results with a bad circuit.

    method 1:

    method 2:

    Anyone any ideas?

    Thanks

    Here is a circuit I did that uses a bus (right of the ROM output), so it is possible.

    What is it you are trying to do?
