Skill: DFT - DFT (Design for Test) is a specialized domain in the semiconductor/VLSI industry that ensures integrated circuits (ASICs/SoCs) are testable during manufacturing. DFT engineers design and implement test structures such as Scan, ATPG, MBIST, LBIST, and JTAG to improve chip quality, fault coverage, and manufacturing yield.

Key skills to target:
- End-to-end DFT implementation
- Scan insertion & compression, ATPG
- MBIST, LBIST, JTAG/Boundary Scan
- DFT signoff, fault coverage, debugging
- RTL, SoC design flow, STA
- Tools: Siemens Tessent, Synopsys TestMAX, Cadence Modus
- Scripting: TCL, Python, Perl

A DFT Staff Engineer is responsible for designing, implementing, and signing off Design-for-Test (DFT)architecture for complexSoCs/IPs. The roleensures that semiconductor designs are testable, high-quality, and manufacturable, whilebalancing coverage, performance, power, and cost.
Key Responsibilities
- DFT Architecture G Strategy
- Define and implement DFT architecture at block/IP or SoC level




- Specify test methodologies (scan,MBIST, boundary scan,compression)
- Ensure testability built early into RTL design flow
- Balance trade-offs between coverage, area, power, and test time
- DFT Implementation Perform:
- Scan insertion and stitching
- ATPG pattern generation and simulation
- MBIST / LBIST / boundary scan integration
- Develop and validate DFT timing constraints (STA)
- Execute DFT flows at RTL and gate level
- Test Coverage G Ǫuality
- Analyze and improve fault coverage
- Debug scan/ATPG issues and resolve coverageholes
- Optimize:
- Pattern count
- Test cost
- Test time
- Verification G Signoff
- Run DFT verification and DRC checks
- Ensure clean DFT signoff (coverage, timing, power impact)
- Validate patterns using simulation and test tools
- Support DFT integration guidelines at SoC level
- Cross-Functional Collaboration Work with:
- RTL design
- Physical design (PD)
- Verification
- Test engineer
