SIMetrix/SIMPLIS is a circuit simulation suite optimised for the design and development of electronic power systems.

SIMetrix/SIMPLIS comprises the SIMetrix environment with the revolutionary SIMPLIS simulator developed by Transim Technology Corporation. The native SIMetrix SPICE simulator is also included.

Features :
Transient analysis 10 to 50 times faster than SPICE - SIMPLIS is a component level simulator like SPICE but simulates power switching circuits typically 10 to 50 times faster.

Periodic operating point (POP) analysis. POP analysis rapidly locates the steady state operating point of a switching system without having to simulate the startup transient conditions. This considerably speeds the study of effects such as load transients.

Small signal AC analysis. Unlike the static methods used in SPICE, this analysis mode emulates a frequency sweep measurement as might be conducted on real hardware producing gain and phase plots without having to derive averaged models.

SPICE model conversion. SPICE models for MOSFETs, diodes, zener diodes and bipolar transistors may be converted to SIMPLIS format without requiring user intervention.

Fully integrated into SIMetrix environment. The SIMPLIS simulator works in the SIMetrix environment in exactly the same way as its native SPICE simulator. This includes full schematic support, schematic cross probing and all waveform viewer features. Click here for more details of SIMetrix.

Can use SPICE models for power MOSFETs, diodes, zener diodes and bipolar transistors.

Mature. SIMPLIS has been available since 1991 on the UNIX platform and so has stood the test of time.
