SIMPLIS 8.4b Update (2024)

SIMetrix / SIMPLIS 8.4b Update | 25.9 mb

SIMetrix Technologies has released an update to SIMetrix/SIMPLIS 8.40. This product families provide professional circuit design and simulation tools for analog and power electronics engineers.

SIMetrix and SIMPLIS are separate simulators working within the SIMetrix development envionment that provides schematic entry, waveform capture and built-in scripting.

SIMetrix is a mixed-signal circuit simulator designed for ease and speed of use.

The core algorithms employed by the SIMetrix analog simulator are based on the SPICE program developed by the CAD/IC group at the department of Electrical Engineering and Computer Sciences, University of California at Berkeley. The digital event driven simulator is derived from XSPICE developed by the Computer Science and Information Technology Laboratory, Georgia Tech. Research Institute, Georgia Institute of Technology.

Although originally derived from these programs only a tiny fraction of the overall application code can be traced to them. Nearly all of the simulator code is either new or has been rewritten in order to provide new analysis features and to resolve convergence problems.

SIMPLIS is a circuit simulator designed for rapid modelling of switching power systems. An acronym for "SIMulation for Piecewise LInear System", it is supplied with our SIMetrix/SIMPLIS product range.

SIMPLIS is a component level simulator like SPICE but is typically 10 to 50 times faster when simulating switching circuits. It achieves its speed by modelling devices using a series of straight-line segments rather than solving non-linear equations as SPICE does. By modelling devices in this way, SIMPLIS can characterise a complete system as a cyclical sequence of linear circuit topologies. This is an accurate representation of a typical switching power system where the semiconductor devices function as switches. However, a linear system can be solved very much more rapidly than the non-linear systems that SPICE handles. The end result is accurate, but extremely fast simulations, allowing the modelling of complex topologies that would not be viable with SPICE.

SIMPLIS has three analysis modes: Transient, Periodic Operating Point and AC. Transient analysis is similar to the SPICE equivalent but is typically 10-50 times faster. Periodic Operating Point is a unique analysis mode that finds the steady-state operating waveforms of switching systems. AC analysis finds the frequency response of a switching system without needing to use averaged models. This is especially useful for what-if studies on new circuit topologies or control schemes where the small-signal averaged model has not yet been derived.

Because non-linear devices are defined using a sequence of straight line segments, models for such devices are quite different from SPICE models. There are of course many SPICE models available and so in order to retain compatibility with these, SIMetrix/SIMPLIS has the ability to convert models for some types of device into SIMPLIS format. This conversion is performed when the device is placed on the schematic. Devices currently supported are MOSFETs, BJTs and diodes. In the case of MOSFETs and Zener diodes, the conversion is achieved by performing a sequence of simulations using the SIMetrix-SPICE simulator. This method is independent of the method of implementation of the device.

New Features in SIMetrix SIMPLIS Version 8.4 Webinar

About SIMetrix Technologies Ltd. We are an independent company dedicated to providing cost-effective, class-leading analog design tools to the professional engineering community. Our company was borne out of frustration. As professional electronics engineers, we couldn't find a circuit simulator on the market that would give us the features we wanted at a price we could afford... so we wrote our own. That was in 1992.

In 2001 we established a partnership with SIMPLIS Technologies, which created the SIMetrix/SIMPLIS product for analysis of power circuits. We now operate seamless sales channels offering each other's complementary products, although we remain as separate companies.

Hardware
SIMetrix will run satisfactorily on any system that meets all the following requirements:

1. The system is running one of supported operating systems listed above
2. The system meets the minimum hardware requirement for the operating system
3. The system's display has a minimum vertical resolution of 720 pixels and a minimum horizontal resolution of 1024 pixels

Recommended System
If you regularly run large circuit simulations or long runs on smaller circuits, we recommend investing inthe most powerful CPU available. A large RAM system can be useful as this will allow caching ofsimulation data. This will speed up Descriptionting results if a large amount of data is generated. The data isstored to disk in an efficient manner and therefore substantial RAM is not essential unless the circuitsbeing simulated are very large indeed. A high performance bus mastering SCSI disk system will improvesimulation performance a little.

Multi-core Processors
SIMetrix can exploit multiple core CPUs in a number of ways and will benefit from multiple coreprocessors. Note, however, that you will require a SIMetrix Pro or SIMetrix Elite license to be able to usethe multiple core features. Note also that SIMetrix cannot effectively use Hyper-threading
