NL5: circuit simulator you can trust

This is quite strong and ambitious statement. First reaction of any engineer working with circuit simulators is predictable and obvious: why would anybody trust … what’s its name, NL5? And what about my favorite (name one)?

The truth is: every simulator may easily produce inaccurate or even absolutely wrong results. Even LTSpice (sorry, Mike Engelhardt!). Sometimes wrong results can be easily recognized just by looking at weird waveforms. But, unfortunately, very often wrong results will look credible even for experienced engineers.

This happens for various reasons, and, in fact, both user and simulator contribute into it. While user’s contribution can be minimized by education, experience, and common sense, simulators can still do things you’ll never even guess. Sometimes this is caused by flaws of the simulation algorithm, but very often it is done intentionally, without notifying the users.

NL5 was originally designed to minimize any erroneous contribution of the simulation algorithm to simulation results. Thanks to the feedback from many active users, NL5 algorithm is now capable of dealing with practically any circuit. If something goes wrong, most likely this is user’s fault: typos in component parameters, missing wires or connections, or maybe just wrong circuit idea.

What would circuit simulator provide wrong results? That’s what you will learn in the next chapter.
