Question:
Repeat 4.8.1, but now the fault to test for is whether the “Jump” control signal has this fault.
Problem 4.8.1
Let us assume that processor testing is done by filling the PC, registers, and data and instruction memories with some values (you can choose which values), letting a single instruction execute, then reading the PC, memories, and registers. These values are then examined to determine if a particular fault is present. Can you design a test (values for PC, memories, and registers) that would determine if there is a stuck-at-0 fault on this signal?
The following problems refer to the following fault:
