WebDFT, Scan and ATPG. The chip manufacturing process is prone to defects and the defects are commonly referred as faults. A fault is testable if there exists a well-specified procedure to expose it in the actual silicon. To make the task of detecting as many faults as possible in a design, we need to add additional logic; Design for testability ... WebATPG is performed on scan inserted design and the SPF generated through scan insertion. Simulation is the later stage after ATPG, for the validation of the patterns generated in different formats. All the stages are interdependent on each other. Refer below figure to check the interdependency of all the stages. Fig.1.1 – DFT Stages.
