Before diving into the licensing details, it is crucial to understand why PLECS is so highly regarded. Unlike general-purpose simulators (like SPICE or Simulink), PLECS is purpose-built for power electronics.
Key differentiators of PLECS:
You can use PLECS either as a standalone product (PLECS Standalone) or as a toolbox within MATLAB/Simulink (PLECS Blockset).
Plexim provides an excellent set of built-in demonstrations. Go to Help > Examples. Run the following three models: plecs trial license
| License Variant | Duration | Target User | |----------------|----------|--------------| | Standard Trial | 14–30 days (typically 30) | Engineers and researchers. Renewable once per major version. | | Student Trial | 60 days | Students via university email; may be extended for coursework. |
Note: The exact duration may vary by region and request date. Users must request a new license file after expiration.
The 15-state limit restricts model complexity. Examples of feasible models: Before diving into the licensing details, it is
Infeasible models (exceed 15 states):
At 8:15 AM, she exported the plots for her presentation. She went to save the modified model. The trial version allowed saving, but a faint watermark appeared in the diagram: “Generated with PLECS Trial License.”
Her manager wouldn't care. But then, she tried to open the model on her colleague’s computer—the one with the standard node-locked license. The error was brutal: You can use PLECS either as a standalone
“This model contains features not available in your license: Thermal Library, C-Script blocks. Please remove these components or upgrade your license.”
The trial had created a model that her team couldn’t use. The “golden handcuffs.” She was now the only person who could run the full simulation.
Plexim is unique in that they rarely offer a "light" trial. The trial license is remarkably generous. Here is exactly what you unlock:
