Static vs. Dynamic Detection of Bugs in Safety-Critical Code

In the never-ending quest to produce high-quality software, traditional dynamic testing plays a fundamental role. The weakness of dynamic testing is that it is only as good as the test cases. To be effective, a great deal of effort must go into writing or generating good test cases, and doing so can be very expensive.

Using CompactPCI to Build Rugged Embedded Systems

The task-specific nature of an embedded system application typically defines a narrow scope of performance requirements. But the range of options for achieving those requirements are broad — from multicore processors and rugged single board computers (SBCs) to I/O devices and the bus systems that tie everything together. And the choices to be made are critical in their impact on cost, on performance efficiency in computeintensive operations, and on the ability to function reliably in hot, cold, dusty or wet environments.
