What is an Embedded system Testing?
- Embedded Systems Testing Training are electronically controlled system where hardware and software are combined .
- These are computers incorporated in consumer products or other devices to perform application-specific functions.
- The end user is usually not even aware of their existence. Embedded Systems Testing Training can contain a variety of computing devices, such as micro controllers, application-specific integrated circuits, and digital signal processors.
- Most systems used in real life as power plant system, medical instrument system, home appliances, air traffic control station, routers and firewalls, telecommunication exchanges, robotics and industrial automation, smart cards, personal digital assistant (PDA) and cellular phone are example of embedded system.
- Test methodologies and test goals differ in the hardware and software domains.
- Embedded Systems Testing Training development uses specialized compilers and development software that offer means for debugging.
- Developers build application software on more powerful computers and eventually test the application in the target processing environment.
- In contrast, hardware testing is concerned mainly with functional verification and self-test after chip is manufactured.
- Hardware developers use tools to simulate the correct behavior of circuit models.
- Vendors design chips for self-test which mainly ensures proper operation of circuit models after their implementation.
- Test engineers who are not the original hardware developers test the integrated system.
- This conventional, divided approach to software and hardware development does not address the embedded system as a whole during the system design process. It instead focuses on these two critical issues of testing separately.
- New problems arise when developers integrate the components from these different domains.
- In theory, unsatisfactory performance of the system under test should lead to a redesign.
- In practice, a redesign is rarely feasible because of the cost and delay involved in another complete design iteration.
- A common engineering practice is to compensate for problems within the integrated system prototype by using software patches.
- These changes can unintentionally affect the behavior of other parts in the computing system.
- At a higher abstraction level, executable specification languages provide an excellent means to assess embedded-systems designs.
- Developers can then test system-level prototypes with either formal verification techniques or simulation.
- A current shortcoming of many approaches is, however, that the transition from testing at the system level to testing at the implementation level is largely ad hoc.
- To date, system testing at the implementation level has received attention in the research community only as co verification, which simulates both hardware and software components conjointly.
- Co verification runs simulations of specifications on powerful computer systems. Commercially available co verification tools link hardware simulators and software debuggers in the implementation phase of the design process.
- Since Embedded Systems Testing Training are frequently employed in mobile products, they are exposed to vibration and other environmental stresses that can cause them to fail.
- Some embedded systems, such as those in automotive applications, are exposed to extremely harsh environments.
- These applications are preparing embedded systems to meet new and more stringent requirements of safety and reliability is a significant challenge for designers.
- Critical applications and applications with high availability requirements are the main candidates for on-line testing.
