Documentation(info="<html>
<p>Three examples of ideal diodes are shown:
<br>the <strong>totally ideal diode</strong> (Ideal) with all parameters to be zero,
the <strong>nearly ideal diode</strong> with <em>Ron=0.1</em> and <em>Goff=0.1</em>
and the nearly ideal but <strong>displaced diode</strong> with <em>Vknee=5</em> and <em>Ron=0.1</em> and <em>Goff=0.1</em>.
The resistance and conductance are chosen atypically high since the slopes should be seen in the graphics.
</p><p>Simulate until T=1 s.
Plot in separate windows:
Ideal.i versus Ideal.v, With_Ron_Goff.i versus With_Ron_Goff.v, With_Ron_Goff_Vknee.i versus With_Ron_Goff_Vknee.v
