8.2. Key Formal Methods Applied to RTL Verification

Try these first

1. 1.

   What is the main purpose of equivalence checking?

   Hint

   Think about what happens after synthesis.

2. 2.

   Define property checking in the context of RTL verification.

   Hint

   Reflect on how properties are validated.

3. 3.

   What does equivalence checking verify?

   • That two designs are built the same way
   • That two designs behave identically
   • That one design is faster than another

   Hint

   Think about the function of the design after it's processed.

4. 4.

   Property checking relies on what logical framework?

   • Finite State Machines
   • Sequential Logic
   • Temporal Logic

   Hint

   Recall how we describe conditions over time.

5. 5.

   Consider a design with multiple states and transitions. Describe how you would approach using model checking to verify that all safety properties hold. What tools might be useful?

   Hint

   Think about the properties you want to assess as you explore.

6. 6.

   Explain how bounded model checking can be utilized to identify a potential corner case in a design. Provide an example scenario.

   Hint

   Remember the limitations of cycles when forming scenarios.
