SIMPLIS Technologies Announces the Release of SIMetrix/SIMPLIS 8.4

Updated DVM Source and Load Dialogs

The DVM source and load symbol dialogs have been updated to use the Power Supply dialog. This allows the ability to define measurements on the four internal probes (voltage, current, gain or magnitude, and phase) for each of the source and load types.

Schematic Editor Features

Some simple but useful schematic editor features have been developed

• Component insert: when you place a two-terminal component directly over a wire, the wire will automatically split
• Component shorting: similar to the disable feature, this disables a component but at the same time shorting its terminals. Works with all two-terminal components and also multi-terminal components that have been appropriately configured. For example, if you short a bipolar transistor, the collector and emitter will be connected but the base will be open circuit.

C-Code DLL

Your digital control code, written in C, running in SIMPLIS. No gates to layout and no co-simulation engine required means quick implementation and speedy simulation.

Magnetics Design Module

The SIMPLIS Magnetics Design Module (MDM) can be added to any variant of SIMetrix/SIMPLIS Classic, Pro, or Elite to enable the creation of realistic inductor and transformer models from a large, editable and extendable catalog of standard and customizable components (cores, materials, wires, and bobbins). SIMPLIS MDM enables the calculation of detailed and accurate inductor and transformer losses and temperatures.

Multi-Level Lossy Transformer

The Multi-Level Lossy Transformer has multiple levels of complexity for use in different simulation objectives. The transformer can have up to a total of 20 windings, and can be configured with varying levels of complexity:

• Level 0 models an ideal transformer with linear magnetizing inductance. There are no winding resistances nor leakage inductance in this model.
• Level 1 models an ideal transformer with piecewise linear magnetizing inductance. There are no winding resistances nor leakage inductance in this model.
• Level 2 models an ideal transformer with piecewise linear magnetizing inductance. Leakage inductance for the transformer is referred to the first primary winding and DC winding resistances are included in the model.

Power Supply Sources and Loads

Easily convert your source between 6 AC and 13 DC source types and your load between 19 different load types. Also added was the ability to define measurements on the four internal probes (voltage, current, gain or magnitude, phase) for each of the source and load types.

Capacitor/Inductor unit to energy storage converter

No need to calculate Charge vs Voltage or Flux-Linkages vs Magnetizing Current characteristics for capacitors and inductors, respectively. This new tool will allow you to enter your capacitor's Farads vs Voltage or inductor's Henries vs Magnetizing Current characteristics and convert them to a SIMPLIS PWL model.

Updated Controlled Sources with Ideal Limiting

Controlled Sources with Limiting outputs now have the option to have ideally limitted outputs. Previously, the output clamping had some small slope when the gained input signal drove into the clamp. With this new option, the output clamping will be ideal at the levels provided.

To place a controlled source with ideal output limiting, use the Part Selector:
