DFT Engineer - ATPG/MBIST

DFT Engineer

Experience : 5 - 8 Years

Location : Bangalore / Kochi / Chennai / Pune

Job Type : Full-time

About the Role :

We are looking for a skilled Design for Testability (DFT) Engineer with hands-on experience in scan insertion, ATPG, MBIST, DFT simulation, and coverage analysis. The ideal candidate should have practical experience working on RTL and netlist-based DFT flows and strong scripting skills.

Key Responsibilities :

- Perform Scan insertion and generate ATPG patterns for Stuck-At and At-Speed faults.

- Analyze scan coverage and implement techniques to improve test coverage.

- Perform MBIST insertion and simulation for memory testing.

- Work on Boundary Scan, TAP Controller insertion, and IEEE 1500/P1500 architectures.

- Execute DFT insertion flows at both RTL and netlist levels.

- Perform DFT simulations with and without SDF annotation.

- Work with synthesis and formal verification tools as part of the DFT implementation flow.

- Support DC characterization and related test requirements.

- Generate Test Description Language (TDL) for ATE environments.

- Collaborate with ATE and validation teams during silicon/ATE bring-up.

- Develop and maintain automation scripts using Perl and TCL.

- Support Static Timing Analysis activities where required.

- Debug DFT implementation and simulation issues and work with cross-functional teams for resolution.

Tech Stack :

- Tools : Mentor/Siemens EDA, Synopsys, Cadence

- Scripting : Perl, TCL

Required Skills :

- 5 - 8 years of hands-on experience in DFT / Design for Test.

- Strong experience in Scan insertion and ATPG.

- Experience with Stuck-At and At-Speed fault models.

- Hands-on experience with scan coverage analysis and improvement.

- Experience in MBIST insertion and simulation.

- Knowledge of Boundary Scan, TAP Controller, and IEEE 1500/P1500.

- Experience with RTL and netlist-based DFT insertion flows.

- Experience with DFT simulation with and without SDF.

- Good knowledge of synthesis and formal verification flows.

- Strong scripting skills in Perl and TCL.

- Exposure to DFT tools from Mentor/Siemens EDA, Synopsys, and/or Cadence.

- Good debugging and problem-solving skills.

Preferred Skills :

- Experience with Static Timing Analysis.

- Experience with ATE pattern generation and silicon bring-up.

- Knowledge of DC characterization.

- Exposure to advanced SoC/ASIC DFT flows
