The 74ABT74 is a dual D-type flip-flop with positive edge trigger. This device features individual data, clock, set, reset inputs, true outputs, and complementary outputs. It also has two 8-bit ...

The 74AHC1G79 and 74AHCT1G79 are single positive-edge triggered D-type flip-flops. The D input can have predictable operation if it’s stable one set-up time prior to the LOW-to-HIGH clock transition.

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 ...

Timing relationships between signals are critical to reliable operation of digital designs. With synchronous designs, the timing of the clock signal relative to data signals is especially important.
