DFT is a design technique that ensures a digital system is testable. The following are some DFT techniques:
Fault simulation determines the effectiveness of a test set. It simulates the circuit with injected faults to see if the test vectors successfully detect them. This is computationally intensive; techniques like and Deductive Fault Simulation are used to manage runtime. digital systems testing and testable design solution
ATPG is the algorithmic process of creating a set of input vectors that can distinguish a faulty circuit from a fault-free one. The two main algorithms are: DFT is a design technique that ensures a
