Change is a key word in our industry. Technology has progressed so far so fast it is amazing to see how far we have come in such a relatively short time. We are swept downstream in the relentless river of development, buffeted by currents from so many quarters the pattern seems random. Disruptive technologies shove us in one direction as convergence tips us in another...
Failures of semiconductor ICs are typically due to overvoltage or overcurrent for a given junction temperature. This overvoltage can be caused by an external factor or an uncontrolled switching inductance. The overcurrent failure can be caused by excess junction temperature due to excessive power losses and a poor thermal path or an abnormal load current. It is typical for a failure report to state Electrical Over Stress(EOS).

The switches have a minimum dielectric strength
Overall, the latest generations of FPGAs provide the performance engineers need for new designs. And FPGA vendors complement performance with power-saving techniques. In many cases, FPGA design tools consistently aim to implement low-power circuits, but engineers can select performance vs. power tradeoffs as well. Most of those low-power changes occur within the design tools and do not cause engineers to rework their code. But before anyone tries to reduce power, they must understand where the power gets burned. It makes no sense to reduce power consumption in an area that doesn’t burn that much power to begin with.
