the invention relates to a method and system for analyzing the dynamic behavior of an electrical circuit including a multiple layered power distribution system formed by a power grid and a plurality of electrical elements , said multiple layered power distribution system having at least two wiring layers providing a specified supply voltage level to each of said electrical elements , said analysis resulting in a representation that allows a judgment of whether or not the voltage level at any of said electrical elements might leave a predetermined voltage range under the condition that a predetermined number of said electrical elements are driven at the same time span . a first representation of said multiple layered power distribution system is converted into a second representation being formed by an abstraction of the first representation by reducing the complexity of the multiple layered power distribution system by at least one wiring layer , and the dynamic behavior of said electrical circuit based on said second representation of said multiple layered power distribution system is analyzed . advantageously , the method and system according to the present invention can be used for on - chip power supply network evaluation . it is even so efficient to be already used early in the chip development process .
