• Perform first silicon bring-up, engineering validation, functional verification, and characterization.
• Design, review, and debug evaluation boards, interface boards, adapter boards, daughter cards, interposers, breakout boards, and custom validation fixtures.
• Perform board bring-up, power sequencing validation, schematic review, PCB review, and board-level debugging.
• Develop validation platforms considering controlled impedance routing, differential pair routing, impedance matching, insertion loss, return loss, skew matching, and signal integrity.
• Validate and characterize interfaces including PCIe, USB, Ethernet, DDR/LPDDR, MIPI, HDMI, DisplayPort, SATA, UFS, eMMC, SD/SDIO, CXL, UCIe, SerDes, XAUI, and JESD204B/C.
• Execute protocol compliance, interoperability, BER testing, jitter analysis, eye diagram measurements, equalization tuning, and link training validation.
• Capture and analyze waveforms, timing diagrams, protocol transactions, and high-speed signal behavior using laboratory instruments.
• Develop automation scripts for instrument control, data acquisition, regression testing, characterization, and reporting.
• Debug hardware, firmware, software, silicon, and board-level issues while supporting NPI, Engineering Validation (EV), Reliability, Product Qualification, and Customer Validation activities.
• Prepare validation procedures, compliance reports, characterization reports, and technical documentation.
• Collaborate with cross-functional engineering teams to resolve validation and product performance issues.
