    • 3 Responses to "New Gate Design Using LTspice/SwitcherCAD III" Helmut Sennewald Says: April 15th, 2008 at 12:37 pm. Hello, It's more safe to make JK- and T-flipflops based on the A-device dflop (D-flipflop). This dflop is already only edge sensitive as required. You can find the examples in the Files-section of the LTspice group.
      • For help with LTspice DFLOP, see this shackexchange topic. Likely some logic thresholds are not set properly. The default voltage levels for logic elements are 1V, and your input never goes below 1V; thus the output is always High. However, the bigger problem is with the "recommended" circuit.

      • The 74LVC1G80 provides a single positive-edge triggered D-type flip-flop. Information on the data input is transferred to the Q output on the LOW-to-HIGH transition of the clock pulse. The input pin D must be stable one set-up time prior to the LOW-to-HIGH clock transition for predictable operation.

    The reason I did it was because I wasn't very pleased with the way LTspice highlights the netlists. It does a crude job by only making the text blue for any lines beginning with a SPICE directive (dot), green (or dark green) for any line that is a comment (starts with *, ;, or #), red for any continued line (+ at the beginning), and black for ...
