In the article, the author discusses how he tests his own software. He claims that he tests his software over and over again during the development stage to avoid debugging, hand checking and to do it all over again. He cites several software checking techniques like desk checking, single-stepping and random-number testing. He also explains how to use the Mathcad software in the testing process.

The article discusses the methods through which embedded systems could diagnose during breakdown. According to the author, embedded systems still produce error messages but the systems are no longer threatened by such error messages. The author suggests a basic step in making diagnosis which involves capturing the logs and checking the error messages.

The article offers information on different standards that Lauterbach Development Tools helped to develop for embedded systems design and in support of the TRACE32 debugger. These are the OSEK Run Time Interface (ORTI) standard which deals with descriptive language, NEXUS standard which deals with debug and trace interfaces, and the IEEE 1149.7 which covers the communication between debugger and core processor. The firm will launch the QorIQ High-Speed Serial Trace, with a NEXUS protocol-based trace technology, at the 2010 Embedded Systems Conference.

The article explains how the concepts of asymmetrical mutiprocessing (AMP) and symmetrical multiprocessing (SMP) systems can be applied using TRACE32 to debug an ARM Cortex-A9 MPCore. It discusses the effect of AMP and SMP on the configuration and usage of a TRACE32 debugger, as well as the process by which the system tasks are distributed to the individual core processors. Guidance is also provided for displaying trace information from an AMP and SMP systems.
