Verilog Reduction Operators

The unary reduction operators shall perform a bitwise operation on a single operand to produce a single-bit result. For reduction and, reduction or, and reduction xor operators, the first step of the operation shall apply the operator between the first bit of the operand and the second using below logic Tables.
The second and subsequent steps shall apply the operator between the 1-bit result of the prior step and the next bit of the operand using the same logic table.
Reduction unary and operator:

Reduction unary or operator:

Reduction unary exclusive or operator:

For example: below table shows the results of applying reduction operators on different operands-

Verilog Operators and Operands

We will understand the various Verilog operators and operands, their types, and their applications in digital circuit design.
Verilog operators are symbols that represent computations or operations on operands. They are classified into several categories based on their functionality.

Arithmetic operators:
Arithmetic operators perform mathematical operations on operands. Common arithmetic operators in Verilog such as addition, subtraction, multiplication, division, and modulus.

reg [3:0] result;
reg [3:0] a = 3;
reg [3:0] b = 5;
always @* begin
    result = a + b;   // Addition
    result = a - b;   // Subtraction
    result = a * b;   // Multiplication
    result = a / b;   // Division
    result = a % b;   // Modulus
