Simultaneous Multi Voltage Analysis with Dynamic Voltage Frequency Scaling

Paul Berevoescu (Synopsys)

Low power has become a critical design goal for multiple applications, from ear pods and smart watches to data centers and AI applications. Low power design methodologies are now ubiquitous, with increasingly complex signoff requirements for verification across an extensive analysis space spanning multiple voltages and frequencies. Substantial time and compute resources are needed for a comprehensive coverage of this analysis space, with potential negative impact on design closure TAT. This talk reviews some of the solutions currently used to perform Static Timing Analysis of designs at multiple voltages and frequencies and introduces Simultaneous Multi Voltage Analysis with Dynamic Voltage Frequency Scaling [SMVA with DVFS], a new method reducing the exponential complexity of the current solutions to quasi linear in the number of targeted voltage levels.
