Which parameter should I changed in Diode model to prevent explosion current exceeded

In ADS simulation, I met the following error:

Warning detected by hpeesofsim during HB analysis `HB3'.
Circuit converged with at least one device's P-N junction current
exceeding the explosion current and junction has been linearized.
You may want to increase the explosion current in the device model or in
the Options (if the parameter is not given in the model) and resimulate.
You may need to increase Maximum number of warnings under Output tab
in Options to see which devices have been linearized.
Warning detected by hpeesofsim during HB analysis `HB3'.
Diode `XN3.DIODE4' explosion current exceeded. I used Varactor Diode model.

Which parameter ( I used Varactor Diode model.) should I changed in Diode model to prevent explosion current exceeded?

Diode Spice model defines few currents: Saturation Current - IS, Reverse Current at Breakdown - IBV, Recombination current parameter - ISR, High-injection knee current - IKF.
In your situation I would increase IBV

Thank you very much, vfone.

You can increase "explosion current" by setting "Imax" and "Imelt" in Options Component.

But I don't think your following problem can be resolved by increasing them.
