HICUM WS 19Motivation
Modeling engineers require software to:I Store and manipulate large amounts of data from
different sourcesI Perform circuit simulations with different simulatorsI Perform TCAD simulations with different simulatorsI Extract compact model parametersI Fit data using models
Markus Müller, 13/14.05.2019 Motivation Slide 3
HICUM WS 19Compact Modeling Toolkit - General Definitions
I Objectorientation
I FrameworkI InterfaceI Toolkit
Different things, same behaviour
Use existing tools to create new things :)!
Markus Müller, 13/14.05.2019 Compact Modeling Toolkit Slide 4
I Do not build every tool from scatch!I Provide examples and documentation!I Use distributed version control in order to let engineers
work together!I Use an easy to learn, yet powerful high-level language!I Do not rely on proprietary software!
