Dynamic voltage scaling (DVS) is a powerful technique that allows the core voltage of an SoC to be decreased or increased during runtime to account for junction temperature (TJ) changes, reduce power dissipation, or increase the performance of the SoC. AMD devices might require DVS to compensate for low temperatures or increase power savings. This application note describes the hardware and software changes that need to be implemented to support this feature for low-temperature compensation for -2LI stock-keeping units (SKU) of AMD Versal™ adaptive SoCs.
