Design Verification Engineer
Mar 2024 – Present
Worked at a semiconductor company on functional and protocol verification for digital and SoC designs, with emphasis on AMBA APB compliance and testbench development.
Tech Stack: Verilog, QuestaSim, Vivado, APB, AMBA, Waveform Analysis, Coverage Analysis, Assertion-based Verification, Constrained Random Verification, Testbench Development
- Designed and implemented a modular, reusable APB-focused verification testbench in Verilog to validate address/data/control transactions using QuestaSim and Vivado for simulation and synthesis validation.
- Developed constrained-random and directed test suites to exercise APB read/write transactions and edge conditions, increasing functional scenario coverage and surfacing protocol mismatches during pre-silicon verification.
- Authored assertion-based checks and coverage metrics targeting handshake sequences and transfer states; analyzed coverage results to identify gaps and iteratively close coverage closure items.
- Performed waveform analysis and protocol-level debugging on failed transactions to identify root causes of timing and handshake issues; coordinated findings with RTL designers to implement fixes.
- Managed verification lifecycle tasks including test planning, regression execution, test-case maintenance, and tracking of verification issues through the bug-tracking process to ensure systematic closure.
- Prepared engineering documentation and presented verification results and defect analyses in design reviews, improving cross-team visibility of protocol compliance and verification status.
Projects
Verification of AMBA - APB | Oct 2025 – Present
Tools Used: Verilog, APB, QuestaSim, Waveform Analysis, Constrained Random Verification, Assertion-based Verification, Coverage Analysis
- Verified AMBA APB protocol behavior across address, data, and control signals to ensure proper communication and handshake compliance between SoC components.
- Created protocol-focused test scenarios covering normal and corner-case read/write sequences and used simulation waveforms to debug transaction-level failures.
- Implemented coverage-driven checks and assertions to validate transfer sequences and response behaviors; iteratively closed coverage gaps through additional directed and randomized tests.
