Hardware Verification With SystemVerilog: An Object-oriented Framework
Verification is increasingly complex, and SystemVerilog is one of the languages that the verification community is turning to. However, no language by itself can guarantee success without proper techniques. Object-oriented programming (OOP), with its focus on managing complexity, is ideally suited to this task.
With this handbook―the first to focus on applying OOP to SystemVerilog―we’ll show how to manage complexity by using layers of abstraction and base classes. By adapting these techniques, you will write more "reasonable" code, and build efficient and reusable verification components.
Both a learning tool and a reference, this handbook contains hundreds of real-world code snippets and three professional verification-system examples. You can copy and paste from these examples, which are all based on an open-source, vendor-neutral framework (with code freely available at www.trusster.com).
Learn about OOP techniques such as these:
- Creating classes―code interfaces, factory functions, reuse
- Connecting classes―pointers, inheritance, channels
- Using "correct by construction"―strong typing, base classes
- Packaging it up―singletons, static methods, packages
Why Read This Book
You should read this book if you want a practical, code‑centric guide to applying object‑oriented design to SystemVerilog testbenches so you can manage verification complexity and produce reusable components. It delivers many real-world code examples and three complete verification system case studies you can adapt for your projects.
Who Will Benefit
Verification engineers and FPGA/ASIC designers who write SystemVerilog testbenches and want to adopt OOP best practices to build maintainable, reusable verification infrastructure.
Level: Advanced — Prerequisites: Familiarity with digital design and Verilog/SystemVerilog basics plus some understanding of object‑oriented programming concepts (classes, inheritance) and common verification concepts.
Key Takeaways

How It Compares
Covers similar verification ground to 'SystemVerilog for Verification' (Spear & Tumbush) but is more focused on applying OOP patterns and providing a small framework and worked examples rather than a broad language tutorial; it also predates and is less centered on the UVM standard.
