Because of commercial pressures from members of the Bluetooth SIG most of the profiles are suited to media and file transfer applications on mobile phones. Consequently, development using Bluetooth profiles is not trivial and can make the standard somewhat unwieldy for simple applications.

Because of commercial pressures from members of the Bluetooth SIG most of the profiles are suited to media and file transfer applications on mobile phones. Consequently, development using Bluetooth profiles is not trivial and can make the standard somewhat unwieldy for simple applications.

In developing for quality versus testing for quality, Schubert, Vitkin, and Winters note [Ref. 4], In a traditional design approach, system requirements are verified at the conclusion of a design cycle, typically after the atomic subsystems have been integrated up through successive levels of abstraction until the system is complete. In some cases, for example when delivery schedules are compressed, the subsystems are often verified after the design, implementation and build process, not during.”

The obvious drawback of this approach is the late discovery of higher-level errors in either the derived requirements or the implemented design. In a traditional development, the algorithm is a passive component of test environment: It executes the functionality-based input stimulus and produces the output results. The problem is that those input stimuli are developed to verify the correctness of the requirements. They do not typically cover all 'abnormal' behavioral conditions.”

In model-based development, a model is an active component and a source for the generation of model-coverage test scenarios. The combination of functionality-based input stimulus and model-coverage based input stimulus create a complete test environment for rigorous validation of the model and verification of software implementation at each step of development.”

The first example to be discussed here [from Ref. 5] is a virtual system prototype of a single-unit, rollover detection ECU, which displays remarkable results:

Benefits of using a virtual system prototyping approach for this rollover detection unit are:

If we calculate the capacitance of the technology (Ctech ) used for the PLL and then calculate the power consumed in performing a lock and acquisition. The power consumed by the PLL is simply the sum of the power consumed during the lock and acquisition.

Table 1 shows the default values for the PLL parameters for 0.18 micron technology that were used in the simulations.
