Recreating JK flip flop in DSCH , none of the designs work.

  1. Dec 7, 2011 #1
    Hi, I'm using DSCH3.5 and I'm trying to build a JK latch. I've found 3 different designs online (which confuses me) and I've recreated them in the software but they aren't functioning at all. Does anyone know what's going on? I'm losing a lot of sleep over this I must be doing something silly.

    It initializes to this:

    I'll add that I created a D flip flop and it works fine. Sorry about the messy wiring on the JK above, it was the third time I had made it.

    I figured it out. I had to put an input button on the inner part of the circuit bwt the two NAND gates (with the wires crossing) onto one of the lines. I'm not sure why but it works.
