NOKIA is seeking a Principal DFT Engineer to work on cutting-edge ASIC implementation for their Network Infrastructure Optical Network group. The role involves end-to-end ownership of DFT insertion, verification, and test coverage closure, requiring collaboration with various engineering teams to achieve silicon success.
Responsibilities:
- You will be working on DFT architecture and implementation across logic BIST, MBIST, BISR, Boundary Scan, and JTAG
- Perform hands-on DFT implementation and verification, including:
- Logic BIST and scan compression
- MBIST and BISR
- Boundary Scan (IEEE 1149.x) insertion
- JTAG insertion and connectivity
- High-speed analog/mixed signal IP integration
- Execute DFT verification, debug, and DFT DRC closure
- Identify, debug, and resolve DFT rule violations at both block and top levels
- Run, analyze, and debug DFT/RTL checks, working with design teams to close violations
- Generate, simulate, and debug MBIST and logic ATPG patterns
- Analyze test results and drive test coverage improvement and closure
- Develop and validate DFT timing constraints for scan, BIST, and test modes
- Create and maintain TCL scripts to automate DFT insertion, verification, and analysis flows
- Support hierarchical DFT implementation and resolve integration issues
- Collaborate with RTL and Physical Design teams to address DFT-related design issues
- Support pre-silicon DFT signoff and assist with post-silicon pattern bring-up and debug
- Assist with ATE pattern conversion and debug as needed
- Experience with gate-level simulations and debugging with industry simulator tools
Requirements:
- Bachelor's degree in computer science, Electrical Engineering or related fields and 8 years of related professional experience OR Master's degree and/or PhD in Computer Science, Electrical Engineering or related fields with 5 years of experience
- 5+ years of hands-on DFT implementation experience
- Strong proficiency with EDA tools, including: Logic BIST insertion and verification, MBIST / BISR insertion and verification, Boundary Scan (IEEE 1149.x), JTAG and HS Analog/mixed signal IP IOBIST integration, ATPG pattern generation and coverage analysis
- Proven ability to resolve DFT DRCs, connectivity issues, and testability problems
- Strong TCL scripting skills for DFT automation and flow execution
- Experience developing and validating scan and test-mode timing constraints
- End-to-end DFT lifecycle experience, from RTL/netlist through silicon debug
- Strong debugging skills, attention to detail, and sense of ownership
- Excellent verbal and written communication skills
