Senior DFX Design Engineer
DFx micro-Architecture :
Drive technical readiness (TR), that is understand customer requirement and further design relevant DFT/DFD/DFV features. DFT stand for Design for testability (testability from tester), DFD stand for Design for debug (Debug capability in Silicon or customer end) and DFV stand for Design for validation (validate effective with simple flow and method)
Architect and implement DFX strategy, These includes provide uarch solution for TAP, Bscan, Scan, MBIST, IO DFX [ leakage, power, loopback], debug port etc. for test testability and manufacturability.
Define DFx design methodology and uarch to ensure good coverage [Scan and functional] for IP and meet products' DPM requirements
Overseeing the Scan/ATPG definition, design, verification, and documentation
Good and close loop communication across function group (Logic, Val, Ckt, SD, HVM) to ensure a right DFX arch introduce to the IP.
Perform yield analysis improvement and assisting the silicon debug
Analyse product requirement to balance DFX requirements vs products' PPA and cost.
DFx RTL Design :
Require RTL coding, pick up different RTL tool-based solution. Integrate all other DFx sub-IPs into one stop. Along process will require signal/clock connection, timing convergence and etc.
Responsible to patch RTL logic for flawless area along execution phase. Ensure zero RTL design errors (bug free) as ultimate goal for DFx features.
Insert Memory BIST logics, as part of the DFT features to enable High Volume Manufacturing (HVM) Memory screening through tests (Post Silicon team).
Collaborate with geo-diverse teams (CKT, structural design team, SOC/HVM ) in analyzing, debugging and identifying the root cause of issues that arise.
Setup and debug Spyglass-DFT or other ATPG tools, generate ATPG patterns via Mentor Graphic Tessent or other equivalent tools, RTL and GLS test validation to ensure quality design, debug and root cause stuckat and atspeed failure using Mentor GLS testbench in Synopsys VCS tools, and validate chain test in serial testbench.
DFx Validation :
Provide direction and expectation on pre-silicon validation to ensure DFX feature are validated and all scenarios are handled.
Collaborate closely with Post silicon PDE team to enable HVM (high volume manufacturing) testing capability.
Provide post silicon support to enable debug capability.
Track progress of self/sub team to achieve goals timely.
Provide indicators and guidance to management on issues and roadblocks on a timely basis.
BS degree in Electrical Engineering, Computer Engineering or other related field of study with a minimum of 10+ years or MS degree with 8+ years of directly related industry experience in SOC/IP DFx Design and Verification.
Experience with creation of DFX plans, schedules and cost estimates for design/verification efforts
Experience in development of RTL design and validation of IP and SoC DFx.
Experience in working closely with physical design team to ensure timing closure for DFx logic.
RTL design of DFx IP , development of test env, test plan and test execution.
The ability work as an individual and as part of a team to deliver a product starting from the creation of the spec, design and verification.
Need a good understanding of System Verilog, scripting languages like shell scripting, PERL and verification methodologies like OVM, UVM and verification methodologies, sound understanding of test strategies, debug flows, ATPG tools and GLS.
Strong Si debug skills, ATE requirements and understanding of volume test requirements.
Strong Communications skills and the ability to effectively work with cross functional teams.
Very good knowledge of automation concepts and significant experience working on, DFD, TAP, STF, BIST, Scan, BSCAN
Should be able to contribute as IC or technically leading a group of team for a Focus faster DFX convergence
Additional qualifications include:
Familiar with UNIX, and well-versed in Verilog or C Programming
Knowledge in RTL integration and validation methodologies
Familiar with Scan design, methodology, coverage analysis and test validation
Ability to communicate well with counterparts and key stakeholders including cross-site partners
