DFT Engineer (CE-64000845)

Job Title

DFT Engineer (CE-64000845)

Role Summary

Perform design-for-test (DFT) planning, implementation, verification, and pattern delivery for mixed-signal audio SoCs. Work within the mixed-signal audio development team to insert and verify memory BIST and scan, improve test coverage, and support silicon bring-up on ATE.

Experience Level

Mid-level. Prefer candidates with approximately 2+ years of relevant ASIC/DFT industry experience.

Responsibilities

Key responsibilities for this role include:

• Define, implement, and review DFT features in collaboration with design teams.
• Generate, insert, and verify Memory BIST (MBIST) logic.
• Perform scan insertion and ATPG pattern generation.
• Develop and review DFT timing and equivalence checking constraints.
• Verify MBIST and ATPG patterns with gate-level simulations.
• Identify and close test coverage gaps; perform test cost planning and analysis.
• Deliver MBIST and ATPG patterns to product test group and support silicon bring-up on ATE.

Requirements

Must-have technical requirements and skills; preferred items listed separately.

• Hands-on experience in ASIC DFT design and verification.
• Experience with industry DFT EDA tools (examples: FastScan, TestKompress, TetraMAX, Test Compiler).
• Experience with scan insertion, ATPG, and MBIST flow implementation and verification.
• Experience verifying test patterns with gate-level simulation and improving test coverage.
• Experience with test cost planning and delivering patterns to production test teams; support ATE silicon bring-up.

Preferred / Nice-to-have:

• Experience with Verilog, SystemVerilog, or VHDL.
• Understanding of low-power test techniques and test architectures.
• Scripting experience (Perl, Python, TCL) and automation/flow development.
• Familiarity with synthesis, static timing analysis, and timing constraints.
• Experience debugging and root-causing silicon issues; strong written and oral communication.

Education Requirements

MSEE with 2+ years of relevant industry experience, or BS with relevant industry experience.
