Considering the digital switching noise viewpoint, in this paper we illustrate a methodology to compare different logic synthesis techniques by applying a stochastic analysis to switching currents. The technique consists in three main steps. First, we synthesize the Boolean function into two logic expressions (classical SOP form and the three-level 2-SPP form). Then, we simulate the corresponding circuits at transistor level to obtain the switching currents. Finally, we post-process the obtained currents to obtain their amplitude density functions and power spectral densities.

Abstract
Considering the digital switching noise viewpoint, in this paper we illustrate a methodology to compare different logic synthesis techniques by applying a stochastic analysis to switching currents. The technique consists in three main steps. First, we synthesize the Boolean function into two logic expressions (classical SOP form and the three-level 2-SPP form). Then, we simulate the corresponding circuits at transistor level to obtain the switching currents. Finally, we post-process the obtained currents to obtain their amplitude density functions and power spectral densities.
