Design analysis of IC power delivery

Power delivery design plays a critical role in ensuring power delivery integrity and achieving overall design power efficiency. A power delivery network (PDN) consists of a multiplicity of passive and active components, which interact with each other in a complex manner. Under this context, power delivery design is a multifaceted problem and a holistic system optimization involving joint design of the passive distribution sub-network and active voltage converters and regulators is indispensable. This paper provides a succinct review of the related PDN analysis and design problems and motivates the need for system-level co-optimization of key design parameters in order to optimally trade off between power supply noise, power efficiency, area overhead and stability.
