Senior Staff DFT Engineer
RenesasJob Title
Senior Staff DFT Engineer
Role Summary
Join Renesas's Infrastructure Power Business to develop mixed-signal, MCU-based power-management SoCs for datacenter applications. The role leads design-for-test (DFT) for analog and mixed-signal blocks to ensure efficient, high-coverage testability and transfer to ATE.
Work with firmware, verification, and ATE teams to deliver test methods, calibration/trim flows, and verification that tests meet parametric requirements.
Experience Level
Senior-level — 10 years of relevant experience.
Responsibilities
Accountable for DFT strategy, implementation, and verification for analog and mixed-signal blocks.
- Own the test plan for analog and mixed-signal content.
- Ensure observability and controllability of blocks to/from package pins.
- Enable parallel on-chip testing to minimize tester interaction and test time.
- Define test, trim, and calibration requirements for blocks such as PLLs, DLLs, ADCs, and DACs.
- Create block test definitions and procedures suitable for ATE test generation.
- Modify schematics and behavioral models to implement testability features.
- Write and bench-validate firmware to exercise test routines and trim procedures prior to ATE transfer.
- Simulate test routines across PVT and noise to demonstrate adherence to parametric specs.
- Coordinate with design, firmware, verification, and ATE teams to ensure DFT effectiveness and correct test-hardware requirements.
- Balance silicon area cost against test time savings when specifying DFT features.
Requirements
Must-have technical skills and practical experience.
- Expertise in SystemVerilog for test/DFT purposes.
- Experience with Cadence Virtuoso for analog/mixed-signal design and modification.
- Working knowledge of C/C++ for microcontroller firmware used in test and trim routines.
- Fundamental understanding of mixed-signal blocks (ADCs, DACs, PLLs/DLLs) and their testability.
- Understanding of ATE tester limitations and test-time cost drivers.
- Familiarity with firmware and ATE program structure; ability to translate DFT simulations to ATE methods (preferred).
- Experience with lab/bench validation and transferring patterns/firmware to ATE.
Education Requirements
Bachelor's or Master's degree in Electrical Engineering or Computer Engineering.
