OOP Foundations in SystemVerilog
- Classes and Objects
- Handles, new(), and Construction Patterns
- Encapsulation with local and protected
- this, Scope Resolution, and Automatic Lifetime
Inheritance & Polymorphism
- Class Inheritance with `extends`
- Virtual Methods and Override Intent
- Polymorphism and Dispatch Semantics
- `super`, `super.new`, and Overriding Rules
Abstract & Interface Classes
- Abstract Classes with `virtual class`
- Pure Virtual Methods as Compile-Time Contracts
- Interface Classes and `implements`
- No Multiple Inheritance: Interface Classes + Composition
Parameterized Classes & Static Members
- Parameterized Classes with Type and Value Parameters
- Static Members and Static Methods in Class-Based Testbenches
- Specializations, typedef Aliases, and the Per-Specialization Static Gotcha
- Type-Parameter Patterns for Reusable OOP Testbench Design
Copy, Cast & Randomization
- Shallow vs Deep Copy
- clone() and copy() Methods
- Dynamic Cast with $cast
- Randomization with Constraints
What SystemVerilog OOP Lacks
- No Multiple Inheritance (Only Interface-Class Contracts)
- No Operator Overloading
- No Destructors or GC APIs (Handle Lifetime Semantics)
- Missing Features vs C++/Java and Reliable Workarounds
OOP Patterns & UVM Application
- Factory Pattern: Polymorphism with Type and Instance Overrides
- Callbacks and Policy Classes for Open Extension
- Parameterized Components and Agents at Scale
- Singleton and config_db Patterns without Global Chaos
Tricky Pitfalls & Debug
- Object Lifetime and Null Handles
- Handle Aliasing Bugs
- Virtual vs Nonvirtual Traps
- Static and Parameterized Gotchas
