The function variant ( <sw-function-variant>) is described in the following details (compare >Function variants):
Variant identifier References to the variants applicable for this description are given in <variant-def-refs> (compare 2.1.2. Variant handling).
Function definition A semi-formal definition of the function is given in <sw-function-def>. This element is automatically loaded as a rule from the system design tools. The obligatory images are foreseen for accepting diagrams from the system design tool (compare 2.2.4.1.1. Function definition).
Function description An informal description of the function is stored in <sw-function-desc> (compare 2.2.4.1.2. Function description). This is prepared manually as a rule.
Function variables The variables used in the function are listed in <sw-function-variables>. The type of application is also specified (compare 2.2.4.1.4. Function variables).
Function parameters The parameters used in the function are listed in <sw-param-refs>. The type of application is specified as well by means of the attribute [owns] (compare 2.2.4.1.5. Function parameters).
Local data dictionary A local functions data dictionary is installed in <sw-data-dictionary-spec> (compare 2.2.3. Data dictionary).
Application notes Notes on calibration (application) of the present function can be given in <sw-application-notes> (compare 2.2.4.1.8. Application notes).
CARB documentation The documentation for CARB ( California Air Resource Board) can be described in <sw-carb-doc> (compare 2.2.4.1.10. CARB documentation).
Function structure The breakdown of the current function into sub-functions can be given in <sw-decomposition>. An overview of the entire function hierarchy can be generated from this (compare 2.2.4.1.11. Function structure).
