Difference between a Task and a Function in SystemVerilog

In SystemVerilog, the main difference between a task and a function lies in their usage and structure.

Function

A function in SystemVerilog is used to perform a specific operation and return a single value. It can be called within an expression and is ideal for calculations or data manipulations. Functions can only contain procedural statements and cannot execute parallel blocks of code.

Task

A task, on the other hand, is used to group a series of statements or operations together. It can contain both sequential and parallel blocks of code, making it suitable for handling complex procedures or tasks that involve multiple steps. Tasks can be called from other tasks or functions.

Therefore, the main focus keyword "difference between a task and a function in SystemVerilog" clearly highlights the distinction between tasks and functions in SystemVerilog programming language.
