8.2.1. Equivalence Checking

Try these first

1. 1.

   What is equivalence checking?

   Hint

   Think about the purpose of verifying different representations.

2. 2.

   Name one tool used for equivalence checking.

   Hint

   Consider common tools known in EDA.

3. 3.

   What is the main purpose of equivalence checking?

   • To ensure design performance
   • To verify functional equivalence
   • To optimize design

   Hint

   Think about the core focus of verification.

4. 4.

   True or False: Equivalence checking is done before synthesis.

   • True
   • False

   Hint

   Consider the order of verification steps.

5. 5.

   Consider a digital circuit with multiple states. Develop a strategy for verifying equivalence that addresses the state explosion issue.

   Hint

   Think about reducing complexity while retaining key features.

6. 6.

   Given an RTL design for a simple counter, describe the equivalence checking procedure you would use after synthesis.

   Hint

   Focus on checking the outputs and states after synthesis.
