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.
Per: GmVehPwrModPer1

HwTq_HwNwtMtr_T_f32 | Float32 | -10 | 10 | |
Output | TblIdxNr_Cnt_T_u16 | Uint16 | 0 | 511 |
Design Rationale
Processing
Created to reduce static path count and cyclomatic complexity of periodic function. Refer FDD
Local Function #2
Function Name | GetMotTqCmdSca | Type | Min | Max |
Arguments Passed | AssiEna_Cnt_T_logl | Boolean | FALSE | TRUE |
Output | MotTqCmdSca_Cnt_T_f32 | Boolean | 0.0 | 1.0 |
Design Rationale
Created to reduce static path count and cyclomatic complexity of periodic function.
Processing
Sets MotTqCmdSca to 1.0 if AssiEna is TRUE and sets it to 0.0 otherwise.
Local Function #3
Function Name | KeepAssiHwTqTmr | Type | Min | Max |
Arguments Passed | HwTq_HwNwtMtr_T_f32 | Float32 | -10 | 10 |
* TblIdxNr_Cnt_T_u16 | Uint16 | 0 | 511 |
Design Rationale
Created to reduce static path count and cyclomatic complexity of local function #2.
*TblIdxNr_Cnt_T_u16 is an output of this function.
Processing
Refer ‘KeepAssi_HwTqTmr’ block in model.
