About the Role – In this exciting role, you will be responsible for implementing and validating Design-for-Test (DFT) methodologies for complex ASIC and SoC designs. You will work closely with Design, Verification, Physical Design, and Test Engineering teams to ensure high-quality manufacturing test solutions through Scan Insertion, ATPG, Pattern Simulation, and DFT signoff activities. The role offers exposure to advanced DFT methodologies, debugging, and automation within a highly collaborative semiconductor environment.

Key Responsibilities

Execute complete Scan Insertion and DFT implementation for complex ASIC and SoC designs.
Generate and optimize ATPG patterns to achieve target fault coverage and test quality goals.
Perform Pattern Simulation and analyze simulation results to validate generated test patterns.
Debug and resolve DFT DRC (Design Rule Check) violations during implementation and signoff stages.
Analyze fault coverage reports and identify opportunities to improve test efficiency and coverage.
Collaborate with RTL, Physical Design, STA, and Verification teams to ensure DFT readiness and smooth design convergence.
Support manufacturing test requirements, silicon bring-up, and failure analysis activities when required.
Develop and maintain automation scripts using Perl for DFT flow execution, report generation, and debug activities.
Perform DFT quality checks including Scan Chain Verification, DRC analysis, ATPG validation, and pattern certification.
Participate in technical reviews, customer discussions, and process improvement initiatives.
Work closely with global engineering teams to meet project schedules, quality targets, and tape-out milestones.
Contribute to DFT methodology enhancement and best-practice development across projects.

Qualifications – BE/BTech/ME/MTech degree in Electronics, Electrical, Telecommunications, Microelectronics, VLSI Design, or related engineering disciplines.

Required Skills
