ASIC DFT Engineer

Job Title

ASIC DFT Engineer

Role Summary

Develop and integrate design-for-test (DFT) features and IP for Cisco silicon. Work within the Common Hardware Group to enable testability, debug, and diagnostics across RTL, implementation, and post-silicon validation flows for switching, routing, and wireless platforms.

Experience Level

Mid-level - 4 to 8 years of relevant ASIC DFT, test, or silicon engineering experience.

Responsibilities

Primary responsibilities involve implementing and validating test logic, developing reusable DFT IP, and supporting silicon bring-up and debugging.

• Implement DFT features to support ATE, in-system test, debug, and diagnostics.
• Develop reusable DFT IP and integrate testability into RTL and full-chip design flows.
• Coordinate with design, verification, and product development teams for test logic integration and validation.
• Contribute to DFT and physical-design strategies for new device models, including bare die and stacked die.
• Perform gate-level simulation and debug test-timing and silicon issues.
• Provide solutions and debug with minimal mentorship during implementation and post-silicon validation.

Requirements

Must-have technical skills and experience:

• 4–8 years of ASIC DFT, test, or silicon engineering experience.
• Practical knowledge of DFT, test methodologies, and silicon engineering practices.
• Experience with JTAG protocols, scan architectures, memory BIST, and boundary scan.
• Experience with ATPG and EDA toolsets such as TestMax, Tetramax, Tessent, and PrimeTime.
• Verification skills including SystemVerilog logic equivalency checking and test-timing validation.
• Experience with gate-level simulation and debugging using VCS or similar simulators.

Nice-to-have:

• Post-silicon validation and ATE pattern experience; familiarity with P1687.
• Scripting skills: Tcl, Python, or Perl.
• Strong verbal and cross-functional collaboration skills.

Education Requirements

Bachelor's or Master's degree in Electrical Engineering or Computer Engineering is required.
