Ready to Scan

Define and implement DFT architecture for mixed-signal SoCs, including scan, MBIST, LBIST, and boundary scan.
Lead RTL-level DFT insertion, scan chain insertion and optimization, test point insertion, and low-power DFT methodologies.
Own ATPG flow development and execution by generating high-quality stuck-at, transition, and path delay test patterns. Drive coverage closure and pattern optimization and debug pattern failure and silicon correlation.
Develop and integrate DFT strategies for mixed-signal blocks, including wrapper-based approaches, and analog test interfaces and BIST solutions.
Collaborate with RTL, DV, and PD teams to ensure clean DFT integration at RTL and gate-level, and timing and physical constraints alignment (scan reordering, compression, etc.).
Drive DFT verification and signoff, including Scan/ATPG coverage metrics, DRC/Lint checks (DFT rule compliance), gate-level simulation and pattern validation.
Support bring-up and silicon debug activities by analyzing tester failures, yield issues, and ATPG pattern correlation with silicon behavior.
Contribute to methodology development, automation, and flow improvements.

B.S. or M.S. in Electrical Engineering or related field.
7+ years of experience in DFT for complex SoCs.
Strong hands-on experience with RTL DFT insertion (scan, compression, test points), and ATPG tools and flows.
Deep understanding of scan architectures, compression techniques, fault models (stuck-at, transition, bridging, path delay), coverage analysis and closure strategies.
Experience with low-power DFT techniques.
Familiarity with mixed-signal integration challenges and test methodologies.
Strong debugging skills across RTL, gate-level, and silicon.
Nice to Have
Experience with MBIST/LBIST implementation and memory repair flows.
Knowledge of IEEE 1149.x (JTAG/boundary scan) standards.
Experience with multi-voltage domain and power-aware DFT.
