You can simulate a flop with a pair of cross-linked NOR gates.



That would be an SR flop, which -like the JK one- is taught in academia but hardly (if ever) used in industry. I was referring to the edge-triggered D flop; it can also be built from gates but it should be a primitive element. If the object was to have the minimum number of primitive elements in the library, you'd need only a NAND or a NOR gate.


As long as they gave you the ability to compose elements, I'd be all over a circuit simulator that started out with nothing but NAND gates. :)


Wooo that would feel like writing a C program starting with assembly...
