About the role:

Avicena is seeking a talented and detail-oriented ASIC Design Verification (DV) Engineer to join our chip design team. You'll play a crucial role in ensuring the functional correctness, performance, and robustness of our high-speed, low-power digital integrated circuits (ICs) for groundbreaking silicon photonics and optical interconnect solutions. This position requires strong expertise in verification methodology and a commitment to quality.


Responsibilities:

• Testbench Development: Develop comprehensive and reusable verification environments (Testbenches) from scratch using advanced methodologies like UVM (Universal Verification Methodology).

• Verification Planning: Work closely with the architecture and design teams to define and execute thorough verification plans, including feature lists, test strategies, and coverage goals.

• Test Case Creation: Develop constrained-random, directed, and stress tests, as well as necessary sequences, scores, and functional coverage models.

• Functional Debugging: Execute simulations, analyze results, and effectively debug complex functional failures, working with design engineers to identify and resolve root causes.

• Coverage Closure: Drive functional and code coverage closure, identifying coverage holes and implementing targeted tests to achieve tape-out quality.

• Regression Management: Maintain and manage regression suites, optimizing simulation speed and efficiency.

• Formal Verification: Utilize formal verification techniques to prove correctness for critical design properties, such as clock domain crossing (CDC) and complex state machines.

• Scripting and Automation: Develop and maintain automation scripts (e.g., in Python or Perl) to enhance the verification flow and improve efficiency.

Qualifications:

• Required:

• • Education: Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or a related field.

• • Experience: 3+ years of professional experience in ASIC/SoC design verification.

• • UVM Expertise: Strong proficiency and hands-on experience in building and deploying reusable verification environments using SystemVerilog and UVM.

• • Verification Languages: Expertise in SystemVerilog, and knowledge of scripting languages like Python or Perl.

• • Tool Proficiency: Experience with industry-standard EDA simulation and debug tools (e.g., Synopsys VCS, Cadence Xcelium, Mentor Questa).

• • Coverage Driven Methodology: Solid understanding of constrained-random verification and functional/code coverage analysis.

• • Debugging Skills: Excellent analytical and problem-solving skills with a proven ability to debug complex digital logic and verification environments.

• Preferred (Nice to Have):

• • Experience verifying high-speed interfaces, SerDes, or communication protocols like Ethernet and PCIe.

• • Exposure to forward error correction (FEC), scrambling, and other digital data communication techniques.

• • Knowledge of formal verification tools (e.g., Synopsys VC Formal, Cadence JasperGold).

• • Familiarity with low-power verification techniques.

• • Experience with hardware description languages (HDL) like Verilog/SystemVerilog for basic design understanding.

• • Exposure to physical layer (PHY) or mixed-signal verification concepts.
