Software Component Implementation
<The detailed design of the function is provided in the FDD. The detail design shall only be added to the MDD when it is not provided in the FDD or the FDD is not adequate and clarification is needed.>
Sub-Module Functions
The sub-module functions are grouped based on similar functionality that needs to be executed in a given “State” of the system (refer States and Modes). For a given module, the MDD will identify the type and number of sub-modules required. The sub-module types are described below.
<(Note: For multiple init or per functions, insert new headers at the “Header 3” level – subset of “Sub-Module Functions section above” and follow the same sub-section design shown below . If none required, place the text “None”))>
Init: PwrSplyInit1
Design Rationale
None
(Processing of function)………
