Abstract

The invention relates to a control signal connection method of a low-power-consumption module. The method comprises the following steps: determining a control signal input end and a control signal output end of the low-power-consumption module; inputting a control signal output by a power management unit (PMU) from a control signal input end to a control signal input end of the low-power-consumption module; according to the distribution position of the switch unit in the low-power-consumption module, generating a control signal propagation chain main path in snakelike arrangement, wherein the start point of the main path of the control signal propagation chain is the control signal input end, and the end point of the main path of the control signal propagation chain is the control signal output end; and the control signals are serially transmitted to the switch units according to the snake-shaped control signal propagation chain main path, so that the switch units control to open or close an electricity load in the low-power-consumption module according to the control signals.

Description

technical field [0001] The invention relates to the technical field of integrated circuit design, in particular to a control signal connection method of a low power consumption module. Background technique [0002] In the field of low-power design, the most effective way to reduce power consumption is to turn off the power supply. The reason is that no matter how low the voltage, how small the current, how slow the speed or how small the leakage is, it is not as thorough as turning off the power supply completely. [0003] However, for a working chip, it is obviously unrealistic to turn off the power of the whole chip. Then if the non-working modules in the chip can be turned off, while the working modules continue to work, real low power consumption can be achieved. [0004] In existing chips, the power supply network is realized through layers of metal, the top metal is always in a energized state, and the bottom metal is connected to the top metal through layers of hole...
