SIMPLIS Technologies Announces the Release of SIMetrix/SIMPLIS 8.2

New Waveform Viewer

The waveform viewer in version 8.2 is completely new and has been rewritten from the ground up.

The new viewer remains compatible with previous versions but has many new features, higher performance, and improved graphics.

More information

Multi-step Probing

The arbitrary fixed probe now has the ability to plot performance analyses and Monte Carlo histograms.

Component Enable/Disable

Parts placed on a schematic may be disabled without deleting. This leaves the part visible in the schematic but non-functional. Any part can be disabled, including terminals, probes and ground connectors.

Transformer GUI

The dialog boxes used to define all types of transformers, including Ideal Transformers, Ideal DC Transformers (preferred for SIMPLIS) and Saturable Transformers (for SIMetrix) have been improved. Winding polarity is now supported and the winding specification is now a list which is easier to use.

Shift Reference

There may be a case where you have waveform data that does not start at x equals to zero. For example, you have imported oscilloscope waveforms where the time starts at a negative time. Three options exist to shift the waveform in the x-axis (time in the example mentioned). This function is best used on data with a linear x-axis.

Piece-Wise Linear Curve Fit

A new dialog has been added to allow you to quickly obtain a PWL approximation of a curve. Currently, there exists a generic curve fit option and three specialized options for the following device characteristics:

• Charge vs. Voltage of a capacitor
• Flux-Linkage vs. Current of an inductor
• Current vs. Voltage of a diode

DVM Enhancements

Changes to the DVM module include:

• Added a Monte Carlo Testplan that utilizes the DVM sensitivity tolerance file.
• Added Multi-Step and Monte Carlo built-in Testplans. Simplifies the transitioning of your non-DVM schematic to a DVM-enabled schematic.
• Updated the built-in Efficiency Testplan to use Multi-Step. This can exploit the Multi-Core capabilities of Pro and Elite licenses.
• Added a utility to include probes in DVM reports.

Simulation Health Report

Helps diagnose common auto-detectable simulation errors and warnings. When enabled, if you encounter an error or warning that has a recommended solution or suggestion, a Health Report will be displayed.

Pole-Zero Entry Dialog

Enter the Poles and Zeros of your S-Domain Transfer Function instead of the coefficients. The poles and zeros are entered in radians per second (ω); however, by setting the Frequency Scale Factor to 2*π, the entries can be made in Hertz. Depending on the order of the filter, the poles and zeros can be real or complex. The poles and zeros can be located on the left-half plane or the right-half plane.
