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?
