The rise in functions, processing power, and data rates makes power design for high-speed system-on-chips (SoCs) increasingly complex. Modern CPUs, GPUs, FPGAs, ASICs, and other components rely on a growing number of power rails to support their functional blocks, requiring precise sequencing during both power-up and power-down phases. Supply voltage levels are being reduced to minimize power dissipation within the SoC, while stricter power integrity requirements demand higher current on these rails. Multiphase buck converters are becoming the preferred solution for high-current power rails, offering numerous advantages. However, they also present unique challenges for power design and validation testing.
