Digital systems testing and testable design are essential aspects of digital system development. By applying testable design techniques and DFT, digital systems can be designed to be testable, reducing testing time and cost. BIST and scan testing are effective testing techniques used to detect faults. A testable design solution involves designing the system with testability in mind, applying DFT techniques, generating test patterns, testing the system, and diagnosing faults.
For systems where external testing is impractical (e.g., spacecraft, implantable medical devices), BIST embeds test generation and response analysis directly into the chip. digital systems testing and testable design solution
