#7 Falling Edge Triggered D and JK Flip Flop


Hello Team,

After working through many examples I would really
like to have falling edge triggered D and JK
flipflops. I hope this would not be too difficult.

    This is easy easy easy. All we have to do is create a copy
    of the JKFF and DFF and declare their clock pin to be
    inverting. The difficult part (and why we didn't make them
    in the first place) is adding an inversion bubble to the
    schematic for the part. Also, we would then have 4 versions
    of each, with combinations of (2 clock edge triggers) *
    (High-active vs. Low-active). I think we wanted to wait
    until we could add bubbles via the parameters setting box
    before we created these particular parts. But they could be
    made pretty easily in the mean time.

    I would like to keep the rising edge parts as well, for backward compatability with old files. It is currently "deprecated" in our code, complete with dialog message and all. ,'o)
