   • Ability to define verification objectives, strategies, coverage metrics, and methodologies (e.g., directed testing, constrained random testing).
3. Verilog and SystemVerilog
   • Proficiency in Verilog and SystemVerilog for creating testbenches and verifying digital designs.
   • Skills in writing RTL (Register Transfer Level) code, defining test scenarios, and simulating design functionality.
4. Verification Environments
   • Techniques for building and configuring verification environments.
   • Skills in developing testbenches, integrating models (e.g., DUT - Design Under Test), and creating stimulus for simulation.
5. Coverage Driven Verification (CDV)
   • Implementation of coverage-driven verification methodologies.
   • Skills in defining coverage goals (e.g., functional coverage, code coverage), analyzing coverage reports, and achieving verification closure.
6. Assertion-Based Verification (ABV)
   • Usage of assertion-based verification techniques in digital verification.
   • Skills in writing assertions (e.g., SVA - SystemVerilog Assertions) to capture design constraints and verify functional behavior.
7. Functional Verification Flows
   • Knowledge of verification flows (e.g., simulation, formal verification, emulation).
   • Skills in selecting appropriate verification methods, executing simulations, and analyzing results.
8. Debugging and Troubleshooting
   • Techniques for debugging issues encountered during verification.
   • Skills in identifying root causes of failures, tracing signals, and using debugging tools (e.g., waveform viewers, debuggers).
9. Advanced Verification Techniques
