In modern electronics, the complexity of Integrated Circuits (ICs) scales according to Moore's Law. Millions or billions of transistors are packed onto a single die. This density makes verifying that a physical chip is free of manufacturing defects extremely difficult.
These occur when two or more signal lines are unintentionally shorted together. They are modeled as Wired-AND or Wired-OR functions, depending on the underlying technology (e.g., TTL vs. CMOS). Delay Faults digital systems testing and testable design solution
Uses a Multiple-Input Signature Register (MISR) to compress the massive stream of output data into a single, unique hexadecimal value called a "signature." In modern electronics, the complexity of Integrated Circuits

Test patterns are shifted into the scan chain bit-by-bit (high controllability).
The most common model. It assumes a circuit node is permanently shorted to VDD (Stuck-At 1) or Ground (Stuck-At 0).
Digital systems testing is a crucial step in the development of digital circuits and systems. As the complexity of digital systems increases, testing becomes more challenging and time-consuming. Testable design is an essential aspect of digital system design that ensures the system can be tested efficiently and effectively. In this text, we will discuss digital systems testing, testable design, and solution strategies.
