5 Powering Performance FPGAs, ASICs, and SoC

Today’s FPGAs tend to operate at lower voltages and higher currents than their predecessors. Consequently, power supply requirements may be more demanding, requiring special attention to features deemed less important in past generations. Failure to consider the output voltage accuracy, sequencing, power-on, and soft-start requirements can result in unreliable power-up or potential damage to FPGAs.
