3. Input & Control Interface

The Input & Control Interface is intended for the description of the complete simulation flow process within AMIGOS and includes semantics for mapping a discretized model onto a specific device structure for any complex simulation domain. It is kept as simple as possible and the syntax tries to support `language like commands'.

The user has to define which physical models and boundary conditions should be used, where to read the geometry from and which kind of grid to use for discretization. Default parameters defined in the Analytical Model Interface (AMI) can be overwritten as well as the update modes for eventually defined derivative quantities implicitly defined. Furthermore, the order of interpolation, the time step calculation and adaptation, and the numerical solving methods (direct or iterative) are chosen within the Input & Control Interface.

AMIGOS uses an annotated mesh data structure to represent the physical structure (wafer state) of a device, including materials, interfaces, impurities, defect profiles, stresses and other characteristic quantities. The abstractions used to represent a mapping mechanism from existing models onto a given simulation domain are handled in the following sections representing the basic input needed to solve a differential equation with AMIGOS.

(The following subsections are just for a better understanding of the possibilities to define a simulation flow within AMIGOS, but the reader my also continue with section  4.)
