Abstract :
In this paper we introduce a novel algorithm for efficient computing of the steady state of circuits driven by multi-tone excitation. The efficiency is the result of combining finite difference and the harmonic balance techniques. Unlike existing techniques the algorithm shown here is based on reformulating the underlying system of ordinary DAEs by a system of partial DAEs. The steady state leads to simple boundary conditions for these partial DAEs
