Basic OOP

4.19 Conclusion

Using Object Oriented Programming is a big step, especially if your first computer language was Verilog. The payoff is that your testbenches are more modular and thus easier to develop, debug, and reuse.

Have patience — your first OOP testbench may look more like Verilog with a few classes added. But as you get the hang of this new way of thinking, you begin to create and manipulate classes for both transactions and the transactors in the testbench that manipulate them.

In Chapter 8 you will learn more OOP techniques so your test can change the behavior of the underlying testbench without having to change any of the existing code.
