Alif Semiconductor is revolutionizing the way secure connected AI-enabled embedded solutions are created. We are looking for motivated individuals who want to be involved in a fast-paced environment with cutting-edge technology.
You will be responsible for DFT implementation on a next-generation SoC project.
Responsibilities
- Define & document DFT requirements/Specifications for IP/Block and Chip level
- Execute DFT Lint to identify scan DRC violations and resolution
- Top level and hard macro block level scan insertion with high EDT compression ratio (Hybrid LBIST, EDT IP/ATPG, LPCT EDT, AC scan verification with high speed PLL, MBIST, and IJTAG)
- Plan and Insert MBIST and memory repair (BISR) at RTL
- Generate and port IJTAG ICL/PDL and STIL patterns for MBIST, ATPG, and JTAG tests
- ATPG pattern verification on pre/post-route gate-level netlist including 0-delay and SDF
- Work with backend team for the MBIST/Scan mode constraints generation, scan reorder, VCDs for IR drop analysis during DFT, ECO changes and formal verification (LEC), and timing closure
- Support test engineer for pattern generation, tester debug and failure analysis.
- Work with Test Engineering team during Silicon bring-up and creating flow/scripts necessary for debugging/diagnosing compression LPC ATPG patterns (stuck-at/at speed), MBIST patterns on ATE for development and production programs
- Expert knowledge of Mentor Tessent toolchain
Job Requirements
- Hands-on hierarchical DFT flow experience from RTL to netlist
- Strong knowledge and experience with both JTAG (IEEE1149.1) and IJTAG (1687)
- Experience in inserting EDT, wrapper cells and OCC
- Experience in analyzing DFT DRC violations and fault coverage analysis
- Expertise in ATPG. Debug and resolve ATPG DRC and chain trace issues
- Gate level simulations and debug; both 0-delay and with SDF DFT
- Expertise in using Cadence for scan stitching and Mentor Tessent tool suite for DFT implementation
- Experience in debugging tester/ATE failures, silicon bring-up and yield and test time improvement
- Experience in Perl/TCL scripting and good verbal/written communication skills
- 7+ years of proven DFT execution experience on mixed-signal SoC with first-pass silicon success
