`super`, `super.new`, and Overriding Rules: Exercises

Practice exercises

Exercise 1

A child UVM env overrides build_phase and creates monitors, but parent configuration fetch no longer happens. Fix the override.

Solution

Add super.build_phase(phase) at the top of the child build_phase, then keep monitor creation after the super call so parent config and child construction both execute.

Exercise 2

Define class apb_cfg extends base_cfg where base_cfg initializes mode and timeout. Ensure apb_cfg adds wait_states safely.

Solution

In apb_cfg::new, call super.new(...) first so mode/timeout are valid, then initialize wait_states. Do not duplicate base initialization in child code.
