An automated flow for design validation of switched mode power supply

Abstract

Traditionally SPICE simulations have been extensively used to validate switched mode power supply designs. It takes multiple iterations of each simulation type at a design corner and there are multiple such simulations required over several design corners to find and fix issues, which is tedious and error prone. This paper presents a novel methodology of using detailed analytical circuit equations in addition to simulations for automated validation of power supply design. In this work we propose automatic detection and correction of design issues over required design corners. This significantly reduces the number of simulations required for design signoff and therefore drastically reduces overall design cycle time.
