METHOD OF ANALYSING BEHAVIOUR OF AN INTEGRATED CIRCUIT IMPLEMENTED BY COMPUTER AND COMPRISING THE SELECTING OF PATHS ON THE BASIS OF SEVERAL CRITERIA BELONGING TO DIFFERENT TYPES

摘要

The invention deals with a method implemented by computer, for selecting representative paths for the analysis of the behaviour of an integrated circuit according to a predefined analysis strategy, comprising the identification of the set of paths of said integrated circuit having logic gates and the compiling of a list of the set of said paths, the method furthermore comprising the following steps: the selection of several criteria related to the behaviour of said integrated circuit, said several criteria being chosen from among the following types: topology, usage, sensitivity, environment, criticality; -the determination of values of the criteria selected for each of said identified paths; - the application of a correlation function to aggregate the set of said values of criteria in such a way as to define, for each of said paths, an aggregation criterion value; and - the selection of a subset of representative paths from among the list of the set of said paths, as a function of the value of the aggregation criterion of each of said paths and of the predefined analysis strategy.
