Abstract

The present invention discloses a method for analyzing a state of a power supply network of an integrated circuit in real time. The method comprises: 1, according to power supply routing of an integrated circuit layout, extracting a resistance-capacitance network and forming a power supply network model in a spice format; 2, setting up a power supply unit by utilizing a power supply module in the integrated circuit, and forming a power supply model in a spice format; 3, based on integral circuit simulation, extracting a dynamic power consumption state of each module in the integrated circuit to form a power consumption model; 4, based on the power supply network model and the power supply model, setting up a top layer simulated circuit, wherein the power supply model is connected to a power supply node, and the power consumption model is connected to a power consumption node; and 5, carrying out simulation on the top layer simulated circuit by utilizing a spice tool, and carrying out waveform observation on different nodes to know the state of the power supply network in real time. According to the method disclosed by the present invention, a pressure drop of each node of the power supply network can be accurately analyzed, so that advantages and disadvantages of power supply signal routing can be analyzed, or the pressure drop of each node is used as judgment basis of regulating the number and positions of power supply units.
