Abstract:
1. A system for identifying one or more effects of coupling noise in an electronic circuit, comprising: a victim line, said victim line arranged in the electronic circuit; at least one aggressor line, said at least one aggressor line arranged in the electronic circuit and coupled to said victim line; means for generating a variable first drive signal, coupled to an input of the victim line; means for generating a variable second drive signal, coupled to an input of the at least one aggressor line; means for adjusting a dampening level of the variable first drive signal, coupled to an output of the victim line; means for adjusting a dampening level of the variable second drive signal, coupled to an output of the at least one aggressor line; means for generating a predetermined crosstalk reference signal; means for comparing the predetermined crosstalk reference signal with a crosstalk signal present at the output of the victim line, and generating a signal associated with a level of comparison between the predetermined crosstalk reference signal and the crosstalk signal; and wherein the means for adjusting the dampening level of the variable first drive signal and the means for adjusting the dampening level of the variable second drive signal comprise a plurality of programmable loads.
