Automated Embedded System

Automated Testing Of Embedded Systems

ABSTRACT

Embedded systems are part of crucial real-time applications and are widely used in complex, time crucial projects like rocket launching and nuclear power development projects. So whatever be the design complexity and sophistication, the designed systems should be put to use with utmost guaranteed performance unless which huge losses can incur.

Embedded system is simply a combination of hardware and software that performs the component of a larger system. An embedded system employs a combination of hardware & software (a “computational engine”) to perform a specific function; works in a reactive and time-constrained environment. A software component called as Real-Time Operating Systems makes the hardware counterpart work accordingly.

This paper having considered various issues on testing strategies concludes with a bias on implementing the sophisticated automated testing tools into the testing phase of various design projects. The choice of testing strategy manifests with the designer and hence care must be taken in choosing the appropriate strategy for testing the design.

The more appropriate the automated testing strategy, the more powerful will be the system.
