What's Good About PCB SI PDN Analysis? 16.5 Has Many New Enhancements!
As clock and data frequencies increase and high-speed systems become more densely populated, noise-free power delivery becomes a major challenge for PCB design. When fast switching devices change state simultaneously, power flow ripple propagates through the power delivery system as noise that varies...
