Frequently sked questions:

Q:

Why there is no ideal switch?

A:

Because a rapid change such as that associated with a switch changing state can cause numerical roundoff or tolerance problems leading to erroneous results or timestep difficulties Each, and I repeat Each SPICE program(NI Multisim,Cadence OrCAD,etc.) have switch with RON and ROFF resistance.

Q:

How to select the element below when the two elements are overlapping each other?

A:

Press button,'Send to back':

Q:

Does oscillator work?

A:

Yes,but you have to put a small initial value on some of the reactive elements.(see the examples)

Q:

How to connect elements?

A:

You can connect two elements by tapping on the end of each element. Also you can directly connect element and wire by tapping on the end of the element and then tap on the wire.

Q:

What measures AC voltmeter/AC ammeter?

A:

It measures the root-mean-square (RMS) voltage or current. Any DC component of the signal will be eliminated, so only the AC component of the signal is measured.

Q:

Which model uses BJT(Bipolar Junction Transistor)?

A:

BJT uses Ebers-Moll model.

Q:

Which model uses Diode?

A:

Diode uses Shockley diode model(Shockley diode equation).

Q:

Why there is no piecewise linear model for diode and BJT?

A:

Because Ebers-Moll model and Shockley diode model are more realistic and accurate!

Q:

Is there a plan to allow creation of custom ICs?

A:

Yes,so you can make your own counters, adders, half-adders,operational amplifiers, etc. My plan is to make relays and transformers and after that I will start with the realization of custom ICs.
