When it comes to illogical logic circuits I have to say I was always scratching my head when it came to Edge Triggered D-Type Flip-Flops. These are one of the most common logic blocks in today’s ...

Digital design with combinatorial gates like AND, OR, and NOT gates is relatively straightforward. In particular, when you use these gates to form combinatorial logic, the outputs only depend on the ...

The JK flip-flop augments the behavior of the SR flip-flop (J = Set, K = Reset) by interpreting the J = K = 1 condition as a “flip” or toggle command. In my previous column, we introduced latches and ...

Last time I talked about how to create an adder in Verilog with an eye to putting it into a Lattice iCEstick board. The adder is a combinatorial circuit and didn’t use a clock. This time, we’ll finish ...
