Combinational circuits comprise of NAND, NOT and NOR gates connected for producing advanced switching logic circuits. A combinational circuit is one in which several gates have been combined: Inputs are represented with A, B, C up to ‘n’ numbers while outputs are represented by A’, B’,C...

The use of constructs like ''if-else,'' ''case,'' and continuous assignment ''assign'' are described in detail with the meaningful practical examples. The main focus of this chapter is to describe the design functionality with the synthesizable logic. Even this chapter focuses on the key ...
Combinational circuits are types of digital circuits that output a binary value, based on a set of input signals. These circuits are generally constructed using logic gates such as AND, OR, NOT, NAND, and NOR gates. They do not have any memory elements or feedback loops, meaning the output...
The verilog always block can be used for both sequential and combinational logic. A few design examples were shown using an assign statement in a previous article. The same set of designs will be explored next using an always block. Example #1 : Simple combinational logic The code shown below...

The intention of this correspondence is to begin to open the classical theory of combinational logic to include design with decoders. Several new kinds of implicants are introduced and a variation on the Karnaugh map is shown to be a useful tool. Examples are given (admittedly carefully chosen...
Simplify the boolean expression for each output. Use Karnaugh Maps or Boolean algebra. Draw a logic diagram that represents the simplified Boolean expression. Verify the design by analysing or simulating the circuit. ExamplesIs input greater than or equal to 5? Specification Design a circuit that...
