5.2 Performing Device Simulation

Similar to the simulation of fabrication processes, the simulation-flow-model can be applied to encapsulate simulators which model the electrical behavior of a semiconductor device. We will demonstrate in the following how this can actually be done by building a simulation-flow-model based on the MINIMOS-NT device simulator. Example 5.4 depicts this simulation-flow-model which encapsulates and controls the MINIMOS-NT device simulator. The input port named device defines the semiconductor device to be investigated by MINIMOS-NT. Example 5.5 lists the input deck template used to control MINIMOS-NT.

$\begin{Example} % latex2html id marker 5488\centering\scriptsize \begin{minipa... ...xiliary parameters of the \textbf{si\-mu\-la\-tion-flow-model}{}.} \end{Example}$

We use a template symbol named curve to define a file which tells MINIMOS-NT the sequence of operating points it should compute in order to produce an I/V-curve. The value for this symbol comes from the input port of the simulation-flow-model. Instead of defining an I/V-Curve we could also create template symbols which simply define the electrical potential at various electrical contacts of the device and associate these contacts with ports of the simulation-flow-model, like this is done for the bulk contact.
