Supply voltage qualified rate comprehensive analysis method

A supply voltage qualified rate comprehensive analysis method is characterized by including the following steps of selecting voltage monitoring point categories A, B, C and D, inputting relevant parameters of an analysis and forming a fundamental mathematic model, inputting relevant operating data and forming boundary conditions of the analysis, executing analysis processes, starting manual analysis if accurate reasons can not be acquired eventually, and storing an analysis result to form an analysis conclusion. According to the supply voltage qualified rate comprehensive analysis method, the complex voltage qualified rate analysis which is influenced by various factors is simplified and decoupled, and accuracy and efficiency of the analysis are improved.
