The components of performance analysis considered within the scope of the invention are, in particular, the determination of the speed at which a circuit or a circuit component can generate output signals from input signals, and the noise immunity of the circuit.The process for evaluating the performance of a very high scale integrated circuit comprises:a first step (E1) in which, for each lead (Li) of said circuit, an equivalent coupling capacity value (CTi) relative a fixed potential, is generated as being a sum of the existing real coupling capacity values (Cij) of leads (Lj) of said circuit with said lead (Li), each of which is assigned a weighting coefficient (Kij); anda second step (E2) following said first step (E1), in which a switching time interval ([tid,tif]) in each lead (Li) is generated as being a function of said equivalent capacity (CTi).The fixed potential may be ground.
