Show hintHide hint
Think about the purpose of comparing designs.
Question 2.
Name one tool used for equivalence checking.
Show hintHide hint
Recall the tools discussed in class.
3Question 3.
What does equivalence checking verify?

4Question 4.
Equivalence Checking guarantees that...
- True

Show hintHide hint
Recall the core purpose of this verification.
Question 5.
Consider a scenario where after synthesis, an equivalence checker fails to find equivalence between RTL and gate-level netlist. Discuss potential issues that might arise in the final product.
Show hintHide hint
Reflect on what happens when expected behaviors change.
Question 6.
Describe how you would approach a situation where a tool claimed equivalence but concerns were raised about specific edge cases potentially not being addressed.
Show hintHide hint
Think of verification strategies that support thorough checking.
