Data-flow modeling is a higher level of abstraction in Verilog compared to gate-level modeling. It focuses on how data moves through a design, rather than describing individual gates. This makes the design more compact, easier to write/modify, and closer to RTL style while still retaining some explicitness in signal behavior. Why Use Data-Flow Modeling As

Verilog supports several abstraction levels; gate-level modeling is one of the most concrete. It’s the level where your design is expressed directly in terms of logic gates and their connections. This modeling gives a clear view of how hardware behaves at a physical or near-physical level. What Is Gate-Level Modeling? Common Gate Primitives Here are

Creating a well-structured testbench is crucial for verifying your Verilog design (aka the Design Under Test, or DUT) before committing to synthesis or hardware. A good testbench helps you discover bugs early, validate functionality, and ensures your hardware behaves correctly under different conditions. What Is a Testbench? Components of a Typical Testbench Here are the

In Verilog, the concepts of modules and ports are foundational. They allow you to build hardware designs in a structured and hierarchical way. This article explains what modules and ports are, how they interact, rules for connecting them, and how instantiations work. What is a Module? A module in Verilog is the primary building block

In Verilog, data types define how information is stored, represented, and manipulated in hardware descriptions. Choosing the right type ensures correct behavior, precise simulation, and efficient synthesis. This article covers the main Verilog data types, their uses, and important rules. What are Data Types? A data type specifies: Verilog supports two broad groups of data

Understanding Verilog Lexical Conventions Verilog, a hardware description language (HDL), is widely used for modeling digital systems. Its syntax and structure are influenced by the C programming language, making it accessible to those familiar with C. A fundamental aspect of Verilog is its lexical conventions, which define the basic building blocks of the language. These

Introduction: Advanced Peripheral Bus (APB) is the part of Advanced Microcontroller Bus Architecture (AMBA) family protocols. The Latest version of APB is v2.0, which was a part of AMBA 4 release. It is a low-cost interface and it is optimized for minimal power consumption and reduced interface complexity. Unlike AHB, it is a Non-pipelined protocol,
