Bip_Dio_ex05.in : Human Body Model in a Diode

Every software package contains a full set of examples suitable for that version and are installed with the software. If you see examples here that are not in your installation you should consider updating to a later version of the software. These examples can be used by beginners and advanced users for product evaluation, teaching purposes, and self-training.

Required Modules

Victory Device

2D Simulator
2D MixedMode

This simple example demonstrates transient Human Body Model (HBM) ESD simulation in a simple 1D diode. It shows:

Structure formation using Victory Device syntax.

Material parameters and model set up for non-isothermal simulation.

Transient solution generated by a discharge of a 100pF capacitor through a 1500 Ohm resistor connected to the diode.

The input file consists of two separate runs each starting with the statement go victorydevice. The first one uses the Victory Device syntax to construct a 1D diode structure. The mesh, regions and electrodes are specified as coordinates in the syntax. It is compulsory to use electrode names (and not just numbers) when the structure is used in MixedMode. The doping distribution for the device is constructed from gaussian and uniform analytical functions. The final structure is saved for later use.

The second and final run is in Mixedmode. The syntax for this run is split into two parts. The first part is a SPICE-like circuit description and control cards. This part is bounded by .begin and .end . The second is device parameter syntax. The circuit netlist is written using standard SPICE syntax.

The second run is a transient simulation (uses the .tran statement). Note that a time dependent resistor is used which changes value from 1.e6 Ohm to 1500 Ohm during 1ps.

The device parameter syntax is given after the .end statement. This sets the models, material and contact parameters for the Atlas device.

The currents and voltages for each node, and the maximum lattice temperature in the device versus time, are stored in the file specified in the .log statement.
