Advantage of analysis by using KAS is following.
� Fast Problem Diagnosis
Normally, due to a large amount of logs when diagnosing by looking at text and
viewer, it consumes a large amount of time and effort, but if a developer uses KAS,
it is possible to find problem quickly.
� Reduction of development time
When developing a system, it takes more time to analyze an error, a bug, or
performance improvement than coding works. Therefore, if we can quickly find
the errors and the by using KAS it is possible to decrease developing time.
� Occurrence rate of bug and error
If it is possible to diagnose and solve an error or a bug accurately when developing
a system, we can decrease the occurrence rate of problems. Moreover, as one error
or bug can be the cause of occurrence of another error or bug it is very helpful to
decrease the problem occurrence rate of the whole system by solving one problem
accurately.
� After development
Even though every problem was solved during the development period of
embedded systems, there is 80% possibility of an occurrence rate of problem in
commercialized embedded systems. In other words, there is high possibility of
occurrence rate of problem when an embedded system is used by normal
