Question

Q1. What are the three main types for formal verification and can you give names for industry tools in formal verification?

Q2. Why IoT verification is not easy?

Answer 1

ANSWER

The three main types for formal verification

1. Provability And Automated Verification
2. Weaknesses Of Formal Method
3. The Lightweight Approach

Provability And Automated Verification

• Automated theorem proving are best described as mathematical CAD tools.
• Provability And Automated Verification formally proving computer systems is not a new idea.
• Their methods of proof are based on the traditional mathematical methods.
• Such techniques are time-intensive and less than perfect .

Weaknesses Of Formal Methods   

• They are generally viewed with suspicion by the professional engineering community.
• It usually hamstringing the operations allowed in order to make the notation elegant and the system provable.
• These design limitations are usually considered intolerable from a developer perspective

The Lightweight Approach

• The traditional view of formal methods as highly abstracted schemes has led to formal methods.
• The lightweight approach is a traditional engineering compromise.
• It engineers will have to think more like mathematicians.

Industry tools for formal verification

• Larch
• SML
• HOL
• Petri Nets

Why Internet of Things verification is not easy

• In Internet of Things may think that they face less daunting verification challenges.
• In some cases, there may be little concern about long-term safety and reliability.
• However, internet of Things teams do not “get a pass” when it comes to functional verification.
• Many are in locations not easily accessible.
• This makes repair or replacement difficult.
• “Hidden” internet of Things devices may include factory automation equipment, security cameras, environmental sensors, and heating and cooling controllers.
