ASIC Functional Test (AFT) Engineering Intern

As an ASIC Functional Test (AFT) Engineering Intern, you will join our Hardware Ops team to develop, automate, and execute system-level functional tests on d-Matrix’s Corsair and next-generation silicon. AFT is our board-level test discipline: a single ASIC is seated in a socket on a custom Validation Board (EVB) equipped with thermal control heads, programmable power delivery, sideband control interfaces, and high-speed I/O stimulus—giving you full observability and controllability of the device under test.

Your primary mission: build and extend the Python-based automation infrastructure that orchestrates AFT test sequences, controls sideband interfaces, manages thermal profiles, collects data, and generates pass/fail verdicts—turning what would be manual bench work into repeatable, scalable, production-grade test flows.

What You’ll Do

AFT Automation & Python Scripting

• Develop and extend Python-based test automation frameworks that orchestrate end-to-end AFT sequences on the EVB—from power-on initialization through functional test execution to data logging and verdict generation.

• Write / Modify control scripts for sideband interfaces (I²C, SPI, JTAG, UART, GPIO) to configure device registers, apply stimulus, toggle modes, and read back status during test.

• Automate thermal profiling workflows: script the temperature control heads to sweep across defined thermal corners (cold/room/hot), trigger test sequences at each setpoint, and aggregate results across temperature.

• Build automation for power sequencing and supply margining—scripting programmable power supplies to step through voltage corners while running functional tests and capturing current measurements.

• Create robust logging, data collection, and result-parsing pipelines that automatically tag test runs with device ID, EVB configuration, thermal/voltage conditions, firmware version, and pass/fail outcomes.

• Integrate automation with version control (Git) and CI workflows so test scripts are traceable, peer-reviewed, and regression-tested before deployment.

EVB-Level Functional Test Execution

• Execute and debug functional test sequences on the EVB with a single ASIC socketed, validating chip functionality across boot, firmware load, DIMC core operation, memory subsystem checks, and PCIe link training.

• Bring up and validate new EVB revisions—verifying socket contact integrity, power rail stability, signal quality on high-speed interfaces, and thermal head calibration.

• Run sideband-controlled test modes (BIST, scan, functional patterns) by driving sideband commands from Python scripts and verifying expected device responses.

• Reproduce and isolate failure modes reported from production or characterization, using the EVB’s full debug access (JTAG, trace ports, register dumps) to localize issues.

Data Analysis & Yield Insight

• Analyze AFT results across device populations to identify systematic failure signatures, voltage/temperature sensitivities, and outlier patterns using pandas, NumPy, and matplotlib.

• Build automated reports and dashboards that surface test coverage metrics, pass rates by test block, and failure Pareto charts for product and design engineering teams.

• Support root-cause and failure analysis (RCFA) by correlating AFT data with silicon lot, design revision, and packaging parameters.

Cross-Functional Collaboration

• Collaborate with the manufacturing and operations teams to transition proven AFT automation from the lab into production-floor workflows.

• Document test procedures, automation APIs, and EVB setup guides so your work scales beyond the internship.

• Present findings and recommendations to engineering leadership through clear, data-backed presentations.

What You’ll Bring

Required

• Currently pursuing a M.S. in Electrical Engineering, Computer Engineering, or a closely related field.

• Strong Python programming skills - you should be comfortable writing production-quality scripts that control hardware, parse data, and run unattended. Experience with pandas, NumPy, matplotlib, or similar data/analysis libraries.

• Comfort with hardware-software interaction—you’ve written code that talks to real devices over serial, I²C, SPI, JTAG, UART, or GPIO (even in a lab class or personal project).

• Solid fundamentals in digital circuits and ASIC concepts—you understand clock domains, reset sequences, register access, scan/BIST basics, and why functional test matters beyond structural test.

• Hands-on lab aptitude—you’re not afraid to socket a chip, hook up probes, read a schematic, or debug a board-level issue.

• Familiarity with scripting for automation—writing tools that orchestrate multi-step hardware workflows, parse logs, move data between systems, and generate reports.

• Ability to work on-site in Santa Clara, CA 3–5 days per week for the duration of the 12-week internship.

Preferred (Nice-to-Have)

• Experience with EVB/board-level bring-up or debug—power rail validation, signal integrity checks, or JTAG-based debug on FPGA or ASIC platforms.

• Familiarity with lab instruments (oscilloscopes, logic analyzers, signal generators, programmable power supplies, thermal chambers) and scripting their control via SCPI/VISA or vendor APIs.

• Experience with test automation frameworks (pytest, Robot Framework, or custom hardware test harnesses) and CI tools (Jenkins, GitLab CI).

• Experience with embedded firmware concepts—boot sequences, firmware loading, register map interaction, sideband protocols.

• Prior internship or co-op in semiconductor test, silicon validation, hardware bring-up, or a related discipline.

• Familiarity with PCIe, LPDDR, or high-speed SerDes link training and debug at the board level.
