Question

What do you mean by the term DFT? Describe in brief.

Answer 1

DFT signifies the design for testability. Design for Test or Testability is a methodology which makes sure a design works appropriately after manufacturing, which later facilitates the failure analysis and false product or piece detection.

Other than the functional logic, you require to add up some DFT logic in your design. This will assist you in testing the chip for the manufacturing defects after it come from the fab. Scan, MBIST, LBIST, IDDQ testing and so on are all part of this.
