DFT - Staff DFT Engineer

Join the leading chiplet startup! As an Eliyan Staff DFT Engineer, you will be working at a fast-paced early-stage startup creating technologies that fuel tomorrow’s chiplet based systems with best-in-class power, area, manufacturability, and design flexibility. You will be defining and implementing scan, memory BIST, IEEE 1149.x/1687/1500/1838 structures, and reporting coverage. You will work with a cross-functional team of industry experts that operate from first principles, innovate and push the envelope to create high-volume and high-performance manufacturable products. We offer a fun work environment with excellent benefits.

Key Responsibilities

• Work with the DFT and Chip Architects to define DFT strategy, methodologies, and implementation plan for various projects (chip_level and stand-alone IP blocks such as PHYs and chiplets)
• Implement DFT features in RTL for digital and analog blocks to the defined architecture & plan
• Generate patterns (e.g., 1687 PLDs, 1149.x, MBIST, etc.) and validate the same at the RTL & gate level
• Generate ATPG patterns (SA/TDF/etc.) and validate the same in 0-delay and SDF-delay based simulations.
• Collaborate with Analog/Mixed Signal (AMS) teams to ensure DFT coverage for high-speed interfaces & implement structural tests for digital logic in the analog blocks
• Work with circuit architects on advanced testing techniques such as PRBS-based PHY loopback capabilities, internal measurement of high-speed clock networks, etc.
• Support flow automation and scripting
• Support device bring up in the lab and pattern handoff to operations for high volume manufacturing and qualification (e.g., running patterns in the lab via the TAP controller, post-silicon bring up of patterns on the ATE, pattern bring up for HTOL and other QUAL activities, RMA analysis, etc.)
• Document overall test coverage and mitigation strategy to narrow down holes

Minimum Qualifications

• Proficient in modern DFT/DFx techniques, methods, & tools (scan insert & ATPG, MBIST, etc.)
• Working knowledge of relevant industry standards (e.g., IEEE 1149.x/1687/1500/1838)
• Proficient in Verilog simulation & debug of DFT structures at the RTL & gate level
• General knowledge of digital and AMS circuit design techniques
• Experience in taping out at least 4 designs and bring up of at least 2 designs on an ATE or in the lab
• Proficient in TCL/shell scripting, working knowledge of scripting in one of perl/python or similar languages, working knowledge of other industry standard tools (Make, bug tracking, colab SW)
• Ability to work collaboratively with cross functional team
• BS EE or equivalent, with 6-9 years of experience

Ideal Qualifications

• Deep expertise in modern test methods and DFx methodologies
• Experience in balancing tradeoffs of test time vs complexity (PPA) vs coverage
• Experience in taking a holistic view of a devices test coverage to incorporate the coverage from non-structural tests into the overall coverage analysis
• Experience with delivery of hard and soft IP to internal and external customers, including the ability to create design kit collaterals for the IP
• 3+ experience with Siemens Tessent platform including ATPG, MBIST, iJtag, BS, and SSN flows
• MS/PhD EE or equivalent, with 6-9 years of experience
