| 1. A method for analyzing crosstalk effects in an electronic device comprising:
a) providing a model description of the electronic device, the model description defining a victim net and at least one aggressor
net capacitively coupled to the victim net, wherein the model description is configured for use in a simulation of the dynamic
response behaviour at an output of the victim net with respect to an input signal of the victim net and/or of the at least
one aggressor net, wherein the model description corresponds to a transistor-level description of the electronic device;
b) representing a characteristic property of the dynamic response behaviour as an output function of the simulation, the output
function having a value depending on at least two input parameters of the simulation, wherein the input parameters comprise
a timing of a transition of the input signal of the at least one aggressor net relative to a timing of a transition of the
input signal of the victim net, and wherein the output function represents (i) a measure of noise induced in the output signal
of the victim net, (ii) a measure of delay of the output signal of the victim net with respect to the input signal of the
victim net, or (iii) a measure of the transition time of a signal transition observed at the output of the victim net; and
c) evaluating the output function so as to find an extremum of the output function in a preset range of the input parameters.
