Résumé: | Starting from a good solution approximation has proved to be very efficient to reduce CPU time required by DC
simulation of analog circuits. In order to obtain an additional speedup in DC fault simulation, this paper proposes a new criterion
to end the Newton-Raphson (NR) iterative algorithm before convergence. In the case where an initial solution approximation is
used, the analysis of the NR algorithm behavior until convergence is presented and a threshold-based simulation accuracy
(TBSA) method is then proposed. TBSA stops the iterations when the solution at current NR iteration is enough accurate to
immediately classify the fault. According to the detection thresholds, a CPU time/accuracy tradeoff is achieved without altering
the fault classification results. The proposed method has been validated on 12 MOS and BJT benchmark circuits considering DC
fault simulation under process parameter variations. TBSA is compared to two existing methods which are: standard simulation
until convergence method which is accurate but requires a large CPU time, and single NR iteration method which is very fast but
without any control over the accuracy. All the compared methods reuse the fault-free circuit results as initial solution for each
faulty circuit simulation. It is shown that TBSA requires an intermediate number of NR iterations while achieving correct fault
classification, especially for parametric faults which take advantage of using a more accurate initial solution. |
