A Fast and Accurate Thermal Solver for Chip Thermal Throttling Analysis
DescriptionAs power densities and operating frequencies continue to rise, thermal throttling—commonly known as dynamic power thermal management—has become increasingly critical. Elevated temperatures can lead to performance degradation and system failures, making effective thermal management essential. To address this challenge, we have developed a rapid and precise thermal solver for analyzing transient thermal responses with complex control mechanisms. This solver enables detailed chip benchmarking and temperature sensor optimization, and it also allows for the application of a PID controller during the simulation phase. Furthermore, it can be used alongside our reduced thermal circuit model, which incorporates chip design details and thermal cooling system effects. This thermal solver empowers users to efficiently assess and understand thermal throttling behavior, particularly when transient simulations require extended runtimes and intricate control mechanisms for large-scale applications.
