Module 4 - Introduction to Modeling

Module four represents a distinct shift away from how SIMPLIS works to focus on creating content, both symbols and models. The differences between symbols, models, components, and devices is clearly delineated. The very important topic of subcircuit encryption is introduced and the different encryption schemes are discussed. Finally, a look even further under the SIMPLIS hood is covered, including troubleshooting slow models.

Before starting into the heart of the modeling topics, lets review the key concepts from the first three modules.

Some Key Concepts from the First Three Modules

SIMPLIS models are always Piecewise Linear (PWL) all the time, therefore you need to think in terms of PWL techniques when creating models.
Multi-Level Models allow us to configure the underlying schematic and parameters based on a single "Level" parameter, increasing model flexibility.
The SIMPLIS POP analysis is crucial to your modeling success, as models which POP simulate faster, and can be simulated in the SIMPLIS AC analysis.
Good models can be back-annotated, which loads the circuit with initial conditions, and allows for easier POP convergence.
The netlist preprocessor allows for dynamic model creation every time the simulation is run.
Parameters exponentially increase model flexibility.
The SIMPLIS Multi-Step and Monte Carlo analyses quickly check design robustness over parameter variation.
Schematics can be viewed as templates which define connectivity, while the values can be loaded using Load Component Values.

These eight key concepts form the knowledge base on which you will build your models.
