Testability modeling has been performed for many years. Some of the articles show multiple things to do on a worked example, some are more focused on a particular trick. Design for testability (DFT) has become an essential part for designing very-large-scale integration (VLSI) circuits. There’s been some controversy regarding the merit of using test interfaces as opposed to testing via the user interface. Design for testability techniques offer one approach toward alleviating this situation by adding enough extra circuitry to a circuit or chip to reduce the complexity of testing. On agile teams, testing provides the neccessary feedback to move the workitems to ‘Done’, but there is less time to prepare, execute and report than in a traditional development approach. Design for testing or design for testability (DFT) consists of IC design techniques that add testability features to a hardware product design.
