# Pre Processor Directives
|
|
|
|
powertrain-build uses pre processor directives instead of code switches.
|
|
This means that all code is generated, but the compiler chooses what to compile
|
|
depending of the settings of the directives.
|
|
|
|
|
|
|
|
## Using Pre Processor Calibration Switches to Switch Signals
|
|
|
|
For this use the LogicalCodeSwitch block, otherwse you will end up with dead code.
|
|
|
|
## Code Switches for Signals Consumed in Model
|
|
|
|
Signals that are produced under a code switche and that are used locally in the model,
|
|
need to have a switch on the signal too.
|
|
The switch should be the LogicalCodeSwitch.
|
|
|
|
## Requirements
|
|
|
|
New pre processor directives, e.g. Vc.Pvc.Demo, must also be defined in a code switch configuration document.
|
|
Note that they are defined as, for example, `Vc.Pvc.Demo` in the configuration document and `Vc_Pvc_Demo` in the simulink block.
