Question 1.
What is exhaustive coverage in formal verification?
Show hintHide hint
Think about how many different combinations we can have.
Question 2.
What does formal verification aim to prove?
Show hintHide hint
Consider what characteristics we want to validate in a design.
3Question 3.
What is the primary benefit of exhaustive coverage in formal verification?
- It is less expensive
- It checks all possible input states
- It requires no assertions
Show hintHide hint
Review what it means to check every possibility in a design.
4Question 4.
True or False: Traditional simulation can guarantee that a design is free of bugs.
- True
- False
Show hintHide hint
Consider what limitations traditional methods have.
Question 5.
You are tasked with designing a traffic signal controller that must work correctly under all possible light and pedestrian signal configurations. Discuss how you would use formal verification to ensure exhaustive coverage in testing this design.
Show hintHide hint
Consider what configurations might cause issues in real-world scenarios.
Question 6.
A complex digital circuit design occasionally fails under rare input conditions. Propose a formal verification strategy focused on exhaustive coverage for detecting these failures.
Show hintHide hint
Think about what types of failures are commonly missed during traditional testing.
