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 ...

In this paper, the authors deal with the testable design of conservative logic based sequential circuits by using two test vectors. The conservative logic based sequential circuits are built from the ...

The circuit was constructed to produce a frequency divider with the use of flip flops which are the basic building blocks of sequential logic circuits while forming a T flip-flop configuration. Toggle ...

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 ...

Over the recent years post-silicon SoC validation has become a major bottleneck in IC design. Due restricted design cycle time and test bench limitations almost all the designs are taped-out with ...
