Method, device and system for measuring energy consumption of integrated circuits

Abstract

The embodiment of the invention relates to a method, a device and a system for measuring energy consumption of integrated circuits. The method comprises the following steps: under preset operating conditions, acquiring a resistance matrix of a power source network on a to-be-measured integrated circuit, wherein the power source network consists of a power source output node and a load node connected with the power source output node; acquiring a voltage matrix consisting of voltage between the load node and the power source output node in the power source network within preset measuring time;according to the resistance matrix, the voltage matrix and the voltage relative to the ground of the power source network, acquiring load node energy consumption belonging to power source pins of theto-be-measured integrated circuit in the power source network; and according to the load node energy consumption belonging to the power source pins of the to-be-measured integrated circuit, acquiringtotal energy consumption of the to-be-measured integrated circuit. The method, the device, and the system of the embodiment of the invention can measure large-scale integrated circuits with numerous power source pins and improve measurement precision without changing a to-be-measured integrated circuit plate.

Description

technical field [0001] The invention relates to the field of circuit technology, in particular to a method, device and system for measuring energy consumption of an integrated circuit. Background technique [0002] At present, in order to meet the needs of energy saving and emission reduction, and to develop green and energy-saving products, testing the energy consumption of integrated circuit boards not only needs to test the energy consumption of the entire board, but also conduct energy consumption tests for major components such as modules or chips in the board, and then Provide reference for developers to design single-board power supply. [0003] The existing energy consumption test method needs to modify the circuit board, and add current transformers or sampling resistors to the circuit to be tested for measurement. The measurement accuracy of this measurement method is restricted by the sampling device, and it is difficult to measure large-scale, power-induced An i...
