Diode

Description

The Diode model is simulated as a non-linear resistance. The model considers various factors like forward bias threshold, forward and reverse break over voltage, blocking current, snubber elements, holding current, on/off resistance. Depending on the user's requirement, there is also an option to select the precision functionality, which allows the user to compensate for errors due to digital implementation of the model during the state switching as a function of time step.

The model also includes an option to enable Fail reset mode which produces  a signal if the diode has reached its normal or reverse breakdown voltage or if an untimely firing had happened.
