Senior DFT Engineer

Description

Position Description:

Tesla’s Silicon Development Group is looking for a DFT Engineer to work on custom ASIC design-to-production. You will help drive the state-of-the-art in testability, debug and safety to achieve high test coverage, quality, and safety needed to aggressively deliver very low DPPM, while optimizing the test cost. 

Responsibilities

◦ Define and implement various DFT features at RTL and gates using in-house flows.

◦ Work closely with the physical design team in achieving design closure with DFT features. 

◦ Perform block-level scan insertion, ATPG, coverage analysis, and simulations. 

◦ Run top-level test pattern retargeting and simulations. 

◦ Identify design changes needed for improving test coverage. 

◦ Work with test / product engineering team members on test pattern delivery and Si bring up. 

Requirements

◦ Knowledge of Testability techniques and features (Compressed Scan, Built-in-Self-Test, Loop-Back, Boundary Scan) covering digital logic domain, embedded memories and PHY/IO’s. 

◦ Well versed in JTAG / 1500 / 1687 networks. BSDL, ICL and PDL knowledge preferable.  

◦ Expertise in ATPG, coverage analysis, and zero-delay / SDF-based pattern simulations.

◦ Experience with Cadence DFT tools (Modus and Genus) or Mentor DFT tools (Tessent Shell) preferred.

◦ Good knowledge of Verilog, logic design, circuit design fundamentals as well as timing 

◦ Working knowledge of TCL, python (or another scripting language like Perl) 

◦ Experience in implementation of MBIST and knowledge of repair schemes, algorithms is a plus 

◦ Experience or working knowledge of SERDES, Analog /mixed-signal DFT techniques (like IOBIST, loop-backs etc.) is a plus 

◦ Post Silicon experience in Pattern conversion for Testers, Pattern Bring-up & Debug, Silicon Characterization etc. is a plus 

◦ Degree in Computer Engineering or Electrical Engineering or equivalent experience
