AI Summary

Staff DFT Engineer at Eliyan responsible for defining and implementing DFT strategies, generating patterns and ATPG, and ensuring coverage across RTL and gate levels for chiplet-based systems.

About this role

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
