Dec 11, 2024 · Structural Verilog descriptions assemble several blocks of code and allow the introduction of hierarchy in a design. The following table lists the concepts of hardware structure and their descriptions.

Apr 19, 2025 · Concise Syntax: Verilog has a straightforward syntax that allows for quick and efficient coding of digital circuits. Industry Standard: It is widely used and accepted in the semiconductor industry, making it easier to collaborate with others and access resources.

This Verilog documentation will focus on the structural level of description because it is efficient to code, yet offers a predictable mapping to hardware in the hands of a skilled user.

Verilog, as a hardware description language (HDL), is used to model and simulate digital systems. In this post, we’ll explore the basic syntax rules and code structure of Verilog, which will help you write clear and effective Verilog code. Let’s get started!

Structural Primitives Gate-level N-ary boolean operators: and, or, xor, not, nand, nor, xnor E.g., C = A+B or (C, A, B); E.g., C= A+B+D or (C, A, B, D); That’s about it Transistor-level primitives too Will not use

Mar 28, 2013 · Structural Verilog is usually referred to a Verilog code which is synthesizable (has an accurate and meaningful hardware realization) and is usually written in Register Transfer Level (RTL).

Dec 31, 2024 · Learn Verilog syntax with this detailed guide. Explore comments, operators, data types, number formats, modules, and common errors to boost your hardware design skills.

Structural Verilog and Code Ordering The creation/instantiation of signals and modules as seen so far is considered structural Verilog: the code only describes the connections between different pieces of hardware.

Jan 23, 2023 · Let us describe a 2X1 MUX using structural modeling. Write the boolean expression and make a logic circuit diagram. Y = S ¯ I 0 + S I 1. First, create a module and define input output ports. Make logic gates by instantiating respective logic gate keyword. There is two AND gate, one OR gate and one NOT gate.

Structural modeling in Verilog allows you to represent a design as a hierarchy of modules. Each module can contain its own internal structure, and modules can be instantiated multiple times. This approach is particularly useful for breaking down complex designs into manageable parts.
