This paper is aimed at the design of a kind of wireless sensing SoC of Internet of Things application project, analyze and study the corresponding low-power design and its design for testability technology. This paper starts from the theory of power consumption of the CMOS IC, states the present related technology and the research progress of the large scale integrated circuit low-power design, and describes specifically on the basic approach and technical route of low-power design based on power management and timer management separately. To illustrate that we have made the rationality and reliability of the low power consumption of wireless sensing SoC a reality, this paper also describes the testable method of low power consumption based on scan chain structure. Finally, on the basis of original design of wireless sensing SoC, we use the 0.18um process database refer to the UPF low-power design flow to accomplish the design for low power consumption and testability of the SoC chip, and do the related analyze and confirmation. The main achievements of this paper are stated below: (1)By analyzing the low power consumption theory of chips, build the low-power design and technique process based on the clock control and power control, put forward the low power consumption solution suited to sensing SoC , and design the circuit blocks of the power consumption control and management. (2)Aimed at the problems of effectiveness of low power consumption of chips, this paper proposes a testable project based on built-in self test scan chain structure, and completes the analyze and confirmation by the technology of the test vector optimization. (3) Do the test, logic synthesis and physical layout design using the low- power design process based on UPF, and make the chip meet the demand of application.
