2.6 Summary

From the analysis of the data flow inside a TCAD framework, the following features that a data level must exhibit can be summarized:

• support of many different data types,
• multidimensional arrays of those data types and indexing into those arrays,
• a data type handling mechanism,
• a unit handling mechanism,
• a naming mechanism,
• a reference mechanism,
• a history and versioning mechanism, and
• a (high-level) representation for geometries, grids, and attributes.
