Singapore SUNLUNE (SINGAPORE) PTE. LTD. Full time
Roles & Responsibilities

Job Overview:

We are seeking an experienced AI Chip DFT (Design for Test) Engineer to lead the design and implementation of test architectures for our advanced AI chip designs, ensuring efficient and reliable testing processes. This role involves taking ownership of integrating DFT circuits (Scan, Mbit, Memory repair, Bscan), performing comprehensive simulations, developing high-quality test vectors, and actively contributing to yield improvement and fault analysis.

Key Responsibilities:

  • Lead the design of DFT architecture at the chip level, implementing testing circuits such as Scan, Mbit, Memory repair, and Bscan.
  • Implement DFT circuits and integrate them into the chip, ensuring proper timing constraints for DFT mode convergence.
  • Perform thorough functional verification, pre-simulation, post-simulation, and power simulation of DFT circuits. Troubleshoot and resolve issues effectively.
  • Develop high-coverage, low-cost test vectors and validate them rigorously through simulation and timing analysis.
  • Drive yield improvement efforts and lead fault analysis activities. Take ownership of testing SDC constraint files in testing modes and contribute significantly to timing and power convergence in the backend.

Qualifications:

  • Bachelor's degree in Electronics Engineering, Computer Science, or a related field. Advanced degrees (Master's or Ph.D.) are a plus.
  • Minimum of 7-8 years of experience in DFT, with proven expertise in chip-level DFT architecture design, circuit insertion, and testing.
  • Proficiency in DFT methodologies, including Scan, Mbit, Memory repair, and Bscan.
  • Strong experience with functional verification and simulations (pre/post, power simulation).
  • Demonstrated ability to develop efficient test vectors and perform thorough timing and simulation analysis.
  • Familiarity with yield improvement and fault analysis processes.
  • Experience with DFT tools and scripting languages (e.g., TCL, Perl, Python).
  • Strong problem-solving skills, meticulous attention to detail, and the ability to collaborate effectively with cross-functional teams.
