Markus Müller, 13/14.05.2019 Slide 2

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

HICUM WS 19Compact Modeling Toolkit - Ideal Toolkit

I Modular architectureI Source code available and

DOCUMENTEDI Toolkit for "core" functionalityI Circuit simulator interfaceI TCAD simulator interfaceI Framework for parameter

extractionI GUI

The right tool for the right task.


HICUM WS 19Compact Modeling Toolkit - Existing Solutions

Issues with commercial solutions:I Source code not necessarily

availableI Licensing issues and costI Not in general physics basedI Some rely on GUII Bundled with other

(proprietary) software

Issues with other existing solutions:I Source code not maintainedI Limited documentationI Relies on single "master"

programmerI Limited and complicated to

extend functionality

→ far away from the "ideal" toolkit defined in the last slide!


HICUM WS 19Compact Modeling Toolkit - Lessons Learned

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!

Markus Müller, 13/14.05.2019 Live demo Slide 16

HICUM WS 19Outlook

I Highly automated script based parameter extractionI MOSFET compact modelsI More circuit simulators (ngspice, spectre, Xyce, Qucs...)I More TCAD simulators (COOS, Sentaurus Device...)I More use-cases are possible, like automated benchmark

circuit design.I Improve tests and documentation
