Lack of coordination between asynchronous resets and synchronous logic clocks leads to intermittent failures on power up. In this series of articles, we discuss the requirements and challenges of ...

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 ...

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 74ALVT16823 is an 18-bit bus-interface D-type flip-flop with reset and enable and 3-state outputs. This device is intended to eliminate the extra packages required to buffer existing registers and ...
