WitrynaThis sketch demonstrates the three basic logic gates, AND, OR and XOR. It also shows the usage of input and output elements. Logic gates are the fundamentals of every logic circuit. #2 Half Adder. ... VHDL and Verilog are the most common hardware description languages. We want to support export to at least one of them. WitrynaThe statements are enclosed in a PROCESS block, and are executed sequentially. When creating a behavioral description of a circuit, you will describe your circuit in terms of its operation over time. Let us take the example of simple NAND2 logic gate as shown in following Fig.4.9.1.
