Spice simulation - How to check Max Voltage and max Current

[jumbodas]

How to find out Max Voltage and max Current reached in the whole circuit during simulation?

I just feeling missing parasitic may cause unrealistic values that can upset convergence or simulation time. I only want to add necessary parasitic to drop levels to realistic values.

* Capacitors in particular should have a resistance in series somewhere. If not then the simulator cannot calculate a sensible RC time constant.

* Batteries can only supply so much Amperes. Power supplies have their limits. Mains has its limits, say 15 or 20 Amperes per real-life circuit breaker.

A fraction of an ohm on the supply wire may be sufficient to bring in a touch of realism. Put a scope trace across it to discover how much current your project draws at any one time.

* LC resonant loops display unrealistically high Q without a resistance to act as a damper. Just a fraction of an ohm in the loop can be satisfactory.

Thanks for the feedback. I am more interested in data from simulator not real life actual values. Even if simulation can converge and is fast. I want to see Max Voltage and max Current it ends with.

The reason is in a circuit with lots of non linear feedback can have multiple different stable convergence. If we allows unrealistic high values it may end up in a convergence that is different to real life.
