please answer question 3
What is testing? Why do we need it? What are the four classes of errors that can occur in a digital system? For each class, give an example. What is the difference between a physical fault and a logical fault? Give an example that illustrates the |difference. Briefly explain what the following terms mean: On-line testing Stored-pattern testing Algorithmic testing DC testing At-speed testing Compact testing Guided-probe testing Self-testing Fault Coverage Fault Universe Problem 2.1, 2.2 from the textbook What is a non-procedure RTL language and why do we need it? Problem 3.1, 3.3 from the textbook What is the difference between transport and inertial delays? Illustrate with an example.Explanation / Answer

Physical defects are actually of four types:
Logical Faults are used to represent Physical Faults and simplifies the fault analysis process and reduce the number of fails. It changes logical function of the circuit...
Consider any system in which if any particular hardware is not working well which results in the error in the output. Hence the hardware which result in error can be considered as physical fault. But since in representing through the logical format of 1-ON and 0-OFF this hardware will get the value 0 hence the physical fault at that hardware has been considered as 0 which is known as logical fault since it represents the physical fault using the logical values...
