Exercise 7.11 (Don’t-Care Function Defined by the Outputs of a Global List of Phases). Calculate both the output pattern of the circuit modified in Exercise 7.10 and the don’t-care function caused by this circuit for a successor circuit. Practical tasks:

1 Load the TVL system of Exercise 7.10.

2 What is the maximal number of output patterns that can be observed on a circuit having four outputs.

3 Calculate the output pattern of the circuit modified in Exercise 7.10.

How many patterns can be seen for the outputs (y, y2, y3, y4). Minimize this TVL and show the result.

4 Calculate the don’t-care function fϕ(y, y2, y3, y4) caused by the circuit modified in Exercise 7.10 using formula (7.55) of [18]. Show the calculated don’t-care function.
