Temperature ramp control for integrated circuit chips

Abstract

A circuit system includes a circuit board including a plurality of integrated circuit (IC) chips. The circuit board is configured to be immersed in a two-phase cooling fluid. The circuit system includes a controller. The controller is configured to, in a control process: obtain temperature data indicative of respective internal temperatures of the plurality of IC chips, predict respective future internal temperatures of the plurality of IC chips based on the respective internal temperatures, and adjust clock frequencies and power supply voltages of the plurality of the IC chips such that the predicted respective future internal temperatures are within a target temperature range. A clock frequency of a first IC chip of the plurality of IC chips is adjusted to be different from a clock frequency of a second IC chip of the plurality of IC chips.
