- AC sweep, thermal analysis, and parametric analysis
- C code blocks and Python scripting support
Modeling, simulation, and scopes
The desktop application keeps circuit creation, simulation, and result visualization in the same environment.
Libraries
Libraries across several domains
SIMBA includes electrical, mechanical, magnetic, thermal, and control libraries. This makes it possible to study the electrical circuit together with the rest of the system.
Editor
Intuitive graphical user interface
The interface is designed to be simple to use so engineers can create and modify circuits without a long learning phase.
Solver
Fast transient simulation
The solver adapts to circuit events and time constants to provide strong performance on power electronics models.
Scopes
Real-time scopes
Results can be visualized during and after simulation. The scopes include zoom, waveform analysis, and measurements such as instantaneous, average, RMS, and FFT values.
Advanced analyses in the desktop application
SIMBA Desktop includes several analysis features used in power electronics design and validation.
Steady state
Automatic steady-state detection
SIMBA can detect the steady-state operation of the simulated circuit. This is especially useful during parametric studies where each run can have different time constants.
- Useful during repeated runs
- Helps stop simulations at the right point
- Improves workflow for sweeps
Frequency domain
AC sweep and loop analysis
AC sweep can be used to determine open-loop and control-loop transfer functions over a user-defined frequency range.
- Useful for converter dynamics
- Gain and phase analysis inside SIMBA
- Supports control design work
Thermal
Electro-thermal analysis for switching devices
SIMBA can combine electrical and thermal simulations to study switching and conduction losses in power semiconductors.
- Switching and conduction loss evaluation
- Temperature-dependent data support
- Useful for thermal management studies
Exploration
Parametric analysis
Parametric analysis helps automate a single-parameter variation and the corresponding simulations.
- Useful for sensitivity analysis
- Compare results across several runs
- Simple way to automate variations
Custom control and Python automation
SIMBA Desktop can also be extended with custom control code and Python scripts.
C code
C code block
The control library includes a C code block that lets users write their own control code, include headers, and build custom control model blocks.
Python
Python library
Modeling, simulation, and analysis steps can also be run from Python scripts. This gives a high degree of freedom for automation and advanced studies.
See the Python Library page for more details.
