Job summary

APPLE INC in Cupertino, CA seeks an experienced DFT Engineer to design and implement DFT architectures, write Verilog RTL for DFT logic, and collaborate with design and DV teams on timing, power and verification coverage. You will generate ATPG vectors, debug silicon test vectors, and support test time reduction and silicon diagnosis efforts.

The role emphasizes collaboration across DV and design teams, with a base pay range noted and a comprehensive benefits program.

Qualifications

• Master’s degree or foreign equivalent in Computer Engineering, Electrical Engineering, Electronics Engineering, or a related field and 2 years of experience in the job offered or related occupation.
• Designing and verifying RTL using Verilog hardware description language.
• Knowledge of MBIST, march algorithms and memory fault models.
• Designing Joint Test Action Group (JTAG) architecture and programming DFT control registers for chip testing
• Automating DFT design flows using Python or Perl scripting languages
• Knowledge of STA for timing analysis.
• Running RTL and gate-level simulations using industry-standard tools such as VCS or NCSIM to debug and resolve design issues
• Utilizing Automatic Test Pattern Generation (ATPG) tools for scan pattern generation and fault coverage analysis across various fault models
• Performing silicon failure diagnosis and analysis from Automated Test Equipment (ATE) to improve yield and manufacturing processes
• Applying low-power design techniques to reduce overall chip power consumption

Responsibilities

• Develop and implement DFT architecture and document DFT specifications.
• Implement DFT infrastructure.
• Code Verilog Register Transfer Language (RTL) for DFT logic.
• Collaborate with designers to integrate DFT implementations and run various checks.
• Partner with designers on STA (Static Timing Analysis), physical, power and logical issues.
• Coordinate with DV (Design Verification) team to verify DFT implementations in RTL and Gate level, review verification coverage and implement ECOs (Engineering Change Orders).
• Generate ATPG (Automatic Test Patten Generation) structural test vectors and analyze and improve test coverage.
• Engage with test engineers to debug and bring up test vectors on silicon.
• Support TTR (Test time Reduction) and silicon diagnosis efforts.
• Handle schedules and support multi-functional engineering efforts.
