Q:

What is CTL?

A) computational tree logic B) code tree logic
C) cpu tree logic D) computer tree logic
 
Answer & Explanation Answer: A) computational tree logic

Explanation: The EMC-system is a popular system for model checking which is developed by Clark that describes the CTL formulas, which is also known as computational tree logics. The CTL consist of two parts, a path quantifier, and a state quantifier.

Q:

Which of the following is also known as equivalence checker?

A) BDD B) FOL
C) Tautology checker D) HOL
 
Answer & Explanation Answer: C) Tautology checker

Explanation: The propositional logic technique consists of the boolean formulas and the boolean function. The tools used in this type of logic is the tautology checker or the equivalence checker which in turn uses the BDD or the binary decision diagrams.

Q:

What is HOL?

A) higher order logic B) higher order last
C) highly organised logic D) higher order less
 
Answer & Explanation Answer: A) higher order logic

Explanation: The formal verification techniques are classified on the basis of the logics employed. The techniques are propositional logic, first order logic, and higher order logic. The HOL is the abbreviation of the higher order logic in which the proofs are automated and manually done with some proof support.

Q:

What is meant by FOL?

A) free order logic B) fast order logic
C) false order logic D) first order logic
 
Answer & Explanation Answer: D) first order logic

Explanation: Many formal verification techniques are used and these are classified on the basis of the logics employed. The techniques are propositional logic, first order logic, and higher order logic. The FOL is the abbreviated form of the first order logic which includes the quantification.
