Description

technical field [0001] The present application relates to the technical field of low power consumption design, in particular to an adaptive voltage regulation SoC system and a control method. Background technique [0002] With the process feature size of integrated circuits getting smaller and smaller, and its operating frequency is increasing, chip design is facing more and more challenges, including antenna effect, power / ground network voltage drop, timing closure, power consumption And other issues, especially the challenge of power consumption is particularly severe. On the one hand, gradually increasing application requirements such as 3D (threedimensional, 3D for short) games, Internet of Things devices, etc., have more and more requirements on power consumption; , Voltage, Temperature, referred to as PVT) conditions and working under different aging degrees will have a corresponding impact on the actual working conditions of the chip. [0003] In actual application ...

Problems solved by technology

Generally, in order to solve the influence of the above deviation factors, it is necessary to leave sufficient voltage margin or timing margin in the actual design process of the chip to ensure the normal operation of the chip, but this will also cause a large amount of ineffective power consumption. caused a lot of unnecessary waste
