In Verilog, a module is like a building block that can be used over and over again in a design. It’s like a template that holds the instructions for how a specific part of the design should behave and how it’s structured. You can think of it as a way to create different parts of a digital system at different levels of detail. Modules can represent simple things like basic gates, or they can represent more complex systems. The cool thing is that you can connect these modules together to build bigger and more intricate designs.
Verilog was developed in the early 1980s by Phil Moorby as a means to model and simulate digital circuits. It has since become one of the most widely used HDLs in the industry. Verilog allows designers to describe the behavior and structure of digital systems at various levels of abstraction, enabling them to design and test complex circuits efficiently.
In Verilog, a module represents a block of hardware that performs a specific function. It can be seen as a black box that takes in inputs, performs some operations, and produces outputs. Modules are reusable and can be instantiated multiple times within a design hierarchy.
