SIMBA 24.09
Welcome to SIMBA 24.09! This release introduces several exciting new features, performance improvements, and bug fixes. Get the latest version and check out the new capabilities below.
New Non-Linear Voltage and Current Source Models
SIMBA introduces new models with user-defined expressions for voltage and current sources.
This advanced model allows you to define currents and voltages directly through any mathematical function, including derivatives, without relying on hidden control variables or multiple iterations.
This feature is perfect for modeling complex non-linear behaviors, such as detailed semiconductors, custom motor models, and nonlinear magnetic elements.
JMAG-RT Wound Field Synchronous Motor
Integration of JMAG-RT Wound Field Synchronous Motor is now supported, providing enhanced modeling of this motor type in SIMBA.
2D Look-Up Table Control Model
A new 2D lookup table with a user interface similar to the "Piecewise Linear" control source, using an input value as the table input instead of time.
New Initialization Option for Inductors and Capacitors
SIMBA now supports automatic initialization of initial values for capacitors and inductors, simplifying the simulation setup.
New Version Notification
Starting with SIMBA 24.09, when a new version becomes available, a new menu option will appear with options to read the release notes and download the update.
Subcircuit "Make Unique" Option
In SIMBA 24.09, when a subcircuit is instantiated multiple times, you now have the option to make an instance unique, allowing individual modifications without affecting other instances.
Semiconductor Thermal Initialization Improvement
The thermal capacitance initialization algorithm has been improved. Instead of setting all thermal capacitances to the same temperature, each capacitance will now have an independent initial temperature, based on the thermal gradient across the device.
This improved initialization works for both Cauer and Foster thermal networks and applies when a capacitance or voltage source is directly connected to the thermal pin to read the initial case temperature.
Thermal Device: Show Junction Temperature Control Pin
A new control pin has been added to all thermal devices (e.g., diodes, MOSFETs, IGBTs) to provide the junction temperature as a control signal. The pin's visibility is controlled by a new parameter: Show Junction Temperature Control Pin. This feature allows for dynamic R(on) values based on current and junction temperature.
