Type-Parameter Patterns for Reusable OOP Testbench Design: Interview Questions

Interview Questions for Type-Parameter Patterns for Reusable OOP Testbench Design.

Interview questions

Q1. When should you use a policy type parameter instead of subclassing?

Answer: Use policy parameters for orthogonal algorithm swaps (compare/hash/pack) that should vary independently from object hierarchy.

Q2. How do you keep type-parameterized code maintainable in large UVM environments?

Answer: Define a small set of approved typedef specializations, document type contracts, and avoid unnecessary parameter axes.

Q3. Why is type parameterization useful even with UVM factory overrides?

Answer: Factory controls runtime object substitution, while parameterization enforces compile/elaboration-time type correctness of APIs and storage.
