一种基于CPF格式的低功耗物理设计方法与实现

A low-power physical design method and implementation based on common power format

  • 摘要: 本文提出了一种基于CPF格式的低功耗物理设计流程, 将低功耗设计意图、电源信息、约束条件等整合到CPF文件中, 并且可以用于集成电路设计流程的各个阶段, 保证了设计的高效性与一致性.针对一款MCU电路, 结合CPF文件, 采用多供电电压和电源关断的低功耗技术对其进行物理设计实现.最终软件分析结果表明, 电压降和功耗满足设计要求.

     

    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.
