Terms of use

These plain-language terms apply to pwmsim.com and app.pwmsim.com.

Cost and access

PWMSim is free to use. No account is required. The free app has no limits on the number of runs, circuit size, or session time.

What you may do

• Use the hosted app for any purpose, including commercial engineering work.
• Keep full ownership of your circuits, netlists, schematics, and results.

What you may not do

The app and solver are proprietary and closed source. Unless you have written permission, you may not redistribute, sell, sublicense, modify, decompile, or reverse engineer them. You may not remove the copyright notice.

These limits do not apply to published file formats or measurement steps. They are public so you can move your work to other tools.

No warranty

The app is provided as is, without warranty of any kind. Simulation results are engineering inputs, not certifications. Before building hardware, check important results with your own measurements and existing tools. To the extent allowed by law, the project is not liable for damage caused by using the app or relying on its results.

If PWMSim gives a wrong answer for a supported feature, the correctness policy explains the response. The supported-features page explains the current limits.

Availability

PWMSim is a side project hosted on a free service. The hosted app may change or be unavailable. Files you download remain yours and do not require an account.

Changes

These terms may change for future use. Updates are published on this page.
