Job summary

Graphcore in Bristol is seeking an experienced DFT engineer to join our Silicon team, focusing on design-for-testability for next-generation AI accelerators. You will work on JTAG, IJTAG, Core Test and STA-related flows across pre- and post-silicon stages.

You'll collaborate with design, verification and product teams to define DFT architectures, build robust test vectors and improve yield. Strong Verilog/SystemVerilog and scripting skills are essential.

Qualifications

• Experience with DFT components like JTAG (IEEE 1149.x), IJTAG (IEEE P1687), Core Test (IEEE P1500), SSN, Test Compression.
• MBIST and BISR implementation and verification desired.
• Solid understanding of design verification methodologies for validating DFT features using simulation in pre-silicon designs.
• Exposure to STA constraints development and analysis for DFT modes and SDF simulations would be a plus.

Responsibilities

• Keep up with the latest industry trends in DFT domain and help adopt the latest DFT techniques and methodologies.
• Work closely with design, verification, physical design and product engineering teams to integrate DFT requirements into the overall design process.
• Define and implement DFT architecture and features for next-generation AI designs and support their verification effort.
• Develop efficient DFT flows and methodology compatible with silicon design flows.
• Work with 3rd party IPs to integrate the provided design into the DFT infrastructure.
• Generate structural test vectors, analyze and improve test coverage.
• Work with the product and test engineering teams to ensure successful silicon bring-up and help identify any silicon failures to enhance yield learning and improvement.
