Course Overview:

Design For Testability (DFT) is a specialization in the SOC design cycle, which facilitates design for detecting manufacturing defects.  With the increase in size & complexity of chips, facilitated by the advancement of manufacturing technologies, DFT has evolved as a specialization in itself over a period of time.  DFT Engineers works on introducing various test structures as part of the design flow, on increasing the testability of logic, pads, memories, interconnects.

The course is designed and will be delivered by experts in DFT, as per current industry project requirements.  Importance is given to cover the concepts, methodology thoroughly with right emphasis on hands-on training, using Synopsys DFT tools with at least 50 % time allocated to lab sessions.

Learning Outcome:

At the end of this course, the candidate will be able to:

  • Review, analyse and propose changes to improve testability and implement them.
  • Analyse test coverage, propose changes to improve test coverage to achieve the goal with optimal patterns
  • Generate the patterns for both stuck-at and at speed testing of the design for optimal test cost.
  • Validate the patterns in pre-silicon simulation environment
  • Understanding and applying debugging techniques used in debugging test on silicon in simulation environment

Training Delivery Model:

  • Weekends (Saturdays): Instructor Lead classroom training
  • Weekdays: Lab support through Email and WhatsApp
  • Flexible learning with 24/7 Lab Access from home through VPN
  • Lecture & Lab sessions go hand in hand, like corporate training
  • Sessions will be interactive.
  • Projects at the end of the course.
