Title
Ivory: Early-Stage Design Space Exploration Tool for Integrated Voltage Regulators.
Abstract
Despite being employed in burgeoning efforts to improve power delivery efficiency, integrated voltage regulators (IVRs) have yet to be evaluated in a rigorous, systematic, or quantitative manner. To fulfill this need, we present Ivory, a high-level design space exploration tool capable of providing accurate conversion efficiency, static performance characteristics, and dynamic transient responses of an IVR-enabled power delivery subsystem (PDS), enabling rapid trade-off exploration at early design stage, approximately 1000x faster than SPICE simulation. We demonstrate and validate Ivory with a wide spectrum of IVR topologies. In addition, we present a case study using Ivory to reveal the optimal PDS configurations, with underlying power break-downs and area overheads for the GPU manycore architecture, which has yet to embrace IVRs.
