Hi could someone please help with the circuit software logicworks. I am trying to create a 6-to-64 decoder and did this by cascading smaller decoders. I used 1 2-to-4 decoder and 4 4-to-16 decoders. I used the 2-to-4 as an enable decoder for all the other decoders. I am trying to display the outputs of my 6:64 decoder. The device I used for the 4:16 is a 74154 with active low outputs and enable inputs. So therefore, do I use AND gates to display the maxterms? Do I connect them to binary probes?
Because one thing I noticed is that for each output, it only contains one maxterm. So how would I use an AND gate with two inputs? Do I ground the other input?
Are all my outputs suppose to be 0 or 1? I think it's suppose to be 0 but I just want to make sure.
Could someone experienced with LogicWorks please help me out. I'd really appreciate it.
This is what's stated in the problem:
Show how to implement a 6:64 decoder using smaller decoder parts. Implement your design in LogicWorks using the decoder parts in the 7400.clf library. Make sure your file is ready to simulate to show your decoder works properly. Think of creative ways to display your outputs to be understandable, and be sure to document them for the grader, explaining what (s)he should see. Arrange your circuit so that it fits on one printed page, and so that it is easy for the grader to change inputs and see the results in one screen.
This is a screenshot of what I've done so far. All I need is help with displaying the 64 outputs.
