As Moore’s Law predicted, the increase in plexity and operating frequencies of today’s integrated circuits have enabled the creation of system applications once thought to be impossible. And systems such as camera cell phones, automotive infotainment systems, advanced powertrain controllers and handheld personal puters have been realized as a result. In addition to the increases in process technology, the Electronic Design Automation (EDA) industry has helped to transform the way semiconductor integrated circuits (IC) and subsequent software applications are designed and verified. This transformation has occurred in the form of design abstraction, where the implementation continues to be performed at higher levels through the innovation of design automation tools. An example of this trend is the evolution of software development from the early days of machinelevel programming to the C++ and Java software written today. The creation of the assembler allowed the programmer to move a level above machine language, which increased the efficiency of code generation and documentation, but still tied the programmer to the underlying hardware architecture. Likewise, the dawn of C / C++ pilers, debuggers and linkers helped to move the abstraction layer further away from the underlying hardware, making the software pletely platform independent, easier to read, easier to debug and more efficient to manage. However, a shift to higher levels of software abstraction has not translated to a reduction in plexity or human resources. On the contrary, as integrated systems have bee more feature rich, the plexity of the operating system and corresponding applications have increased rapidly, as have the costs associated with the software implementation and verification activities. Certainly the advancements in embedded software tools such as static code checkers, debuggers and hardware emulators have helped to solve some of the software verification problems, but software verification activities have bee more time and resource consuming than the actual software creation. Timetomarket constraints have pushed software verification activities to the systemlevel, and led to a greater demand for production
