A new method termed compressed time is presented to compute the steady-state response of nonlinear circuits with periodic or quasi-periodic excitation. It is different from standard or enhanced shooting method or harmonic balance (HB) and allows the simulation of large systems such as large circuits and large number of harmonics. It is based on a time domain formulation of HB equations written in a preconditioned form. The generated system is then solved with a nonlinear block relaxation algorithm. Performances and simulation results are shown for a typical RF circuit
