DIGITAL SIGNAL TRANSITION COUNTERS FOR DIGITAL INTEGRATED CIRCUITS

摘要

A digital integrated circuit may include a digital data processing circuit having multiple signal lines that each go through signal transitions during operation of the digital data processing circuit. A digital counter circuit may count the combined number of signal transitions that take place on at least two of the multiple signal lines during operation of the digital circuit. A digital counter circuit may count the number of times a particular pattern of signal transitions takes place on at least one signal line during operation of the circuit. A computer program may receive information indicative of a composition of a digital integrated circuit, input vectors to the digital integrated circuit, and how much power is being consumed by the digital integrated circuit under each of the input vectors. The program may output information indicative of an amount of power being consumed by each of multiple, different sub-sections of the digital integrated circuit while responding to the input vectors.
