Abstract:
In this paper, we propose a low-power physical design flow based on common power format, which contains low-power design intent, power supply information and constraints. Since the CPF file can be used in various stages of the integrated circuit design flow, the efficiency and consistency of the design can be ensured. During the physical design of a MCU circuit, we reduce the power by using multiple supply voltages and power shut down technologies, combined with the CPF file. Finally the results of the power analysis software show that the IR drop and power meet the design requirements.
