Last month we put the ‘R’ into RTL by discussing registers and how to create them in Verilog and VHDL. We learned how to create resets, both synchronous and asynchronous, clock enables, and even…clock ...

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 ...

While it is tempting to write RTL and let the synthesis tool take over, this isn’t the best way to get the results we want. In this article, we’ll learn how to create complex combinatorial code in ...

Designing combinatorial digital circuits seems like it should be easy. After all, you can do everything you want with just AND, OR, and NOT gates. Bonus points if you have an XOR gate, but you can ...
