When I was in university, we used Logisim[0] for our intro to digital logic class. I think you could probably simulate such a computer in this tool if you wanted something intuitive. Otherwise you can prepare your design in a high level logic language like Verilog and test it using Verilator [1]. Naturally there is always a risk when going from running in a simulator to the real PCB.
