Since the very early days of electronic components failures have continuously been appearing. In spite of enormous development and production improvements this situation has not changed. Even automated equipment faults continue to be created on circuit boards. There is not a single manufacturing technique that will guarantee the 100 percent fault free circuit board. Each new technology creates ...

In recent years a lot of new C-based design languages have been developed. They all promise a smoother transition from a high level to a low level description of a hardware system. A disadvantage of these new languages is that a lot of simulation models of e.g. FPGA-cores are only available in standard languages like VHDL or Verilog. This makes it hard to develop a complete system with one of t...

in Chicago, Illinois, April, 1989. C ontemporary philosophers have won­ dered: Do virgin landscapes always possess beauty? Unsullied by human nature, is the natural world invariably aesthetic? Examples in support of a negative reply are not wanting; when lightning causes a ground fIre, the burned out, blackened forest may be experienced as an aesthetic liability, for the expected sights, aromas...
