7.3.4. Symbolic Execution

Try these first

1. 1.

   What is symbolic execution used for?

   Hint

   Think about what happens when you replace actual numbers with symbols.

2. 2.

   Name a tool used for symbolic execution.

   Hint

   What names come to mind when thinking of formal verification tools?

3. 3.

   What is the primary purpose of symbolic execution?

   • To perform simulation
   • To verify design correctness
   • To test specific cases

   Hint

   Think about what verification methods aim to achieve.

4. 4.

   True or False: Symbolic execution only explores a few execution paths.

   • True
   • False

   Hint

   Think about the term 'all possible'.

5. 5.

   Describe how symbolic execution could be effectively applied in verifying a complex digital circuit design intended for aerospace applications.

   Hint

   Consider the critical nature of aerospace systems and the importance of verifying all operational scenarios.

6. 6.

   What measures can be implemented to alleviate the state explosion problem during symbolic execution?

   Hint
