Developing and destroying hardware

Designing commercial electronical circuits always forces compromises between several contradicting natural laws and, to prevent the developer from being bored, further constraints are imposed by economical requirements. The Unholy Alliance of short time-to-market, low costs, slips of the mouse and contradicting design rules causes weaknesses in the hardware that can easily be exploited by programmers and users. We will examin this on circuits using the fieldbus ARCNET.
