tial disadvantage that the device models must provide the implementations of all
functionalities for selection which are needed for all TCs; this increases complexity.
On the other hand, these device models can be applied in a more versatile way; there
is no need for modifications, if the application purpose varies.
For the evaluation and application of textual test scripts by model descriptions
in VHDL-AMS, the test bench requires a so-called script interpreter. Unfortunately,
the script interpreter again enhances the complexity of all model descriptions. When
designing its model-based test system C&S FACTS. Sim, 20 C&S group GmbH de-
cided to choose this version. The focus was on the reusability of test system com-
ponents of the existing FACTS-based test systems as well as on a high degree of
reproducibility and comparability of model-based tests. The complexity of both of
the integration versions is in the same range and therefore this should be of minor
importance, when voting for one version or the other (see Fig. 6.14 ).
20 FACTS stands for Flexible Adaptable Customizable Test System. This is the generic product
name of various test products applied at C&S such as FACTS.CAN.COM/NM and FACTS.
