Simulation
A few words regarding circuit simulation on this website:
- A given circuit can be simulated successfully with one set of inputs but may fail with another.
- The author bases ideal circuits on their understanding of ideal behaviour. This behaviour is implemented using B and E sources, mostly.
- Ideal behaviour is sometimes intrinsically unnatural, making simulation difficult. Ideal models prioritize behaviour over stability.
- Ideal Operational Amplifier (OpAmp) circuits still use operational amplifier models with very large, but finite, gain.
- Ideal circuits have no parasitics (such as extra series / parallel resistance, capacitance, inductance).
- R L C charge circuits set the initial value of capacitors to zero volt and the initial value of inductors to zero ampere.
- Noise is not simulated. Very small and very large values in some circuits, whether shown in the schematic or not, can lead to wiggly lines, looking like noise.
- As circuit complexity increases, simulation tends to become less reliable. It may stop short of the specified time (but rarely frequency), or does not run at all.
- The links in the URL (the browser's address line) should always lead to the same simulation. However, this may not always be possible. Look carefully at the URL, as it may be recoverable by changing a few numbers or letters (the ones after '#') and/or adding new parameters ("REF=VAL,..." between '?' and '#'). A URL with only the '#' will load a circuit with its default parameters.
