Software tools and methods in modeling and extraction

Software is a important issue in the area of device and process characterization. The used software tools can classified to the following applications:

1. Measurement software for IEEE488 - control and data acquisition
2. Extraction software for parameter extraction
   • WEVA - a Program system for parameter extracion of mixed systems and technologies.
   • OPTIMOD - a Program for global SPICE - device parameterization
   • Local working programs for Bipolar modeling, also with consideration of RF behavior, quasi saturation, case description and self heating effects.
3. Macro modeling of complex analog devices with regard of measurement data and data sheet entries
   • OPA and TRANSIMP - Programs for extended modeling of Operational- and Transimpedance amplifier
   • Programs for modeling of OPAs, Transimpedance amplifier and comparators, Model transformation device model - macro model
4. Simulators and Evaluation- and documentation software
   • HSpice, Saber, PSpice, SPICE2G6, Spice3f4 for verification of extracted parameter sets and model continuity in simulator.
   • Data transformation and vizualization with octave and gnuplot.
5. Support programs
   • Layout program for development of test structures.
   • Program PISCES-II for device simulation as a support in technological based device modeling.

A lot of other programs are developed by DAnalyse GmbH, based on a longterm industrial experience. Because of the availability of source code this programs can adapted in a flexible way to the wide range of tasks in measurement and modeling.
