Abstract
A method and system for thermal management in integrated circuits and integrated circuit boards is described. In an embodiment, the circuit device board includes circuit devices, temperature sensors, and a thermal management unit. The thermal management unit receives thermal data from the temperature sensors and determines thermal reference points that define thermal regions. The thermal reference points are correlated with the operating characteristics of the circuit devices. When warranted, the thermal management unit makes independent corrective responses to each of the thermal regions. These corrective responses include modifying operating parameters, adjusting workload, and suspending operation of circuit devices within the thermal region. Thus, the disclosed method and system can preserve function in one thermal region while alleviating stress on another thermal region.
