SIMBA 24.11
Welcome to SIMBA 24.11! This release marks a significant milestone with the introduction of compatibility with manufacturer semiconductor SPICE models. SIMBA is the only software platform to support both thermal description files (.xml) for ultra-fast electro-thermal simulation and native compatibility with SPICE models for in-depth analysis.
This is neither co-simulation nor model translation. In addition to a custom SPICE netlist parser, we have updated the SIMBA solver to ensure compatibility with non-linear models used in semiconductor SPICE models.
Our goal? To provide a unified platform for all types of power electronics simulation.
We've also added new features and improvements to enhance your simulation experience. Read on to discover what's new in this version.
Compatibility with Manufacturer Semiconductor SPICE Models
We are excited to announce that SIMBA now offers compatibility with SPICE models provided by semiconductor manufacturers. This feature allows you to import and simulate detailed power device models directly within SIMBA, enabling more accurate thermal and loss analysis across various operating modes, including Zero Voltage Switching (ZVS) and hard switching.
Validated Manufacturers:
- Infineon
- Wolfspeed
- ROHM
- EPC
This compatibility was showcased at the SIMBA Power Electronics 2024 Conference, where we demonstrated custom loss data generation workflows and their application to system-level thermal and performance analysis.
Example:
Check this example that demonstrates the use of SIMBA to generate custom power switch loss data under Zero Voltage Switching (ZVS) operation mode using the manufacturer's SPICE model.

Benefits:
- Improved Accuracy: Leverage detailed manufacturer models for precise simulations.
- New workflows: Custom Thermal Data Generation
Improved Signal Connection Behavior
We've enhanced the user interface for signal connections to improve the behavior when moving segments. This improvement makes it easier to adjust your schematics and organize connections without disrupting your layout.
New Models: Pulse Generator (Current and Voltage)
Introducing new Pulse Generator models for both current and voltage sources. These models allow you to create custom pulse waveforms with precise control over parameters such as amplitude, pulse width, period, and rise/fall times.
Bug Fixes and Performance Improvements
Our team has been hard at work addressing various bugs and optimizing performance to ensure a smoother user experience.
Key Fixes: - Resolved issues with simulation stability in complex models. - Optimized memory usage during large-scale simulations. - Improved accuracy in thermal modeling under certain conditions.
