VERILOG 9 :Abstraction Levels and Procedural Blocks
Verilog HDL ( Hardware Description Language ) is widely used for modeling digital systems. It allows designers to describe circuits at different levels of abstraction , making it easier to go from high-level behavior to gate-level implementation . In this guide, we’ll explore these abstraction levels, procedural blocks , and important Verilog constructs with practical examples. Abstraction Levels in Verilog Verilog supports multiple modeling styles depending on the level of detail required: Behavioral Modeling Describes the functionality of the design rather than its structure. Suitable for quick prototyping. Example: writing algorithms for counters , FSMs , or arithmetic operations. RTL (Register Transfer Level) Modeling Describes the design in terms of data flow between registers and logic. Mostly used for synthesis into hardware . Structural Modeling Describes how gates, flip-flops, and modules are interconnected. Used for low-level represent...
