A design and test technique for embedded software Abstract: In recent years, embedded systems have become so complex and the development time to market is required to be shorter than before.
Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use today. Modern embedded systems are often based on microcontrollers i. In either case, the processor s used may be types ranging from general purpose to those specialized in a certain class of computations, or even custom designed for the application at hand. A common standard class of dedicated processors is the digital signal processor DSP. Since the embedded system is dedicated to specific tasks, design engineers can optimize it to reduce the size and cost of the product and increase the reliability and performance. Some embedded systems are mass-produced, benefiting from economies of scale.

Many enterprises regard system-level testing as the final piece of the development effort, rather than as a tool that should be integrated.

As a consequence, test teams often execute critical test plans just before product launch, resulting in much of the corrective work being performed in a rush and at the last minute. Presenting combinatorial approaches for improving test coverage, Testing Complex and Embedded Systems details techniques to help you streamline testing and identify problems before they occur-including turbocharged testing using Six Sigma and exploratory testing methods. Rather than present the continuum of testing for particular products or design attributes, the text focuses on boundary conditions.
Today, safety- and mission-critical applications are asking for increasing the system dependability during the operational lifetime. Actually, new standards arose in the last years try to define the minimum requests in order to guarantee reliability of such devices. In fact, during the last years, microprocessor-based safety-critical applications are introducing a series of audit processes to be applied during the whole product lifetime targeting reliability. Some of these processes are common in industrial design and manufacturing flows, including risk analysis, design verification, and validation, performed since the early phases of product development, but very often, additional test processes need to be performed during the product mission life in a periodic fashion to match reliability standards. In this talk, a brief guideline to effectively increase system dependability by exploiting functional approaches is provided.
Недовольно поморщившись, Сьюзан закрыла окно экранного замка, но в ту долю секунды, когда оно исчезало с экрана, она заметила нечто необычное. Снова открыв окно, Сьюзан изучила содержащуюся в нем информацию.
И словно по волшебству в этот момент открылась дверь, и в комнату оперативного управления, запыхавшись, вбежала Мидж. Поднявшись на подиум, она крикнула: - Директор. На коммутатор поступает сообщение. Фонтейн тотчас повернулся к стене-экрану. Пятнадцать секунд спустя экран ожил.
А что, подумала Сьюзан, если броситься мимо него и побежать к двери. Но осуществить это намерение ей не пришлось. Внезапно кто-то начал колотить кулаком по стеклянной стене. Оба они - Хейл и Сьюзан - даже подпрыгнули от неожиданности.
- Откроем пачку тофу.
