A New Strategy for Handling Global Feedback Loops in Selective-Tracing Waveform Relaxation Algorithm for Large Scale MOSFET Circuit Simulation
The selective-tracing waveform relaxation (STWR) algorithm, which combines good properties of traditional relaxation-based algorithms including WR and ITA, has been discussed. STWR is basically a WR algorithm, but it selectively traces and schedules subcircuits for one individual calculation. STWR c...

Summary: | The selective-tracing waveform relaxation (STWR) algorithm, which combines good properties of traditional relaxation-based algorithms including WR and ITA, has been discussed. STWR is basically a WR algorithm, but it selectively traces and schedules subcircuits for one individual calculation. STWR can exploit circuits' multi-rate behaviors, uses dynamical windows (controlled by the convergence situations) in each WR iterations, and spends fewer number of subcircuit calculations in most test circuits. A new global feedback loop controlling method for STWR is proposed in this paper. Properties of proposed methods have been tested by real experiments. |
