Signal Data Types of TargetLink blocks

As stated before, TargetLink blocks behave differently than

corresponding Simulink blocks with regard to non-double data types.

Simulink blocks support numerous inheritance schemes, and for many

blocks the signal output can be set explicitly, which in turn influences

the type of the input signals.TargetLink blocks generally emit doubles

and accept any nonscaled type at their inputs. However, some

TargetLink blocks deviate from this in specific details. In any of these

cases, the different behavior might result in models which cannot be

initialized after Simulink-to-TargetLink conversion.

The following list provides some details. “All Simulink types” means

int8, int16, ..., single, double, boolean

. “Scaled signals

accepted” means that signals which are scaled in Simulink can be fed

into the block. “Same as Simulink” means that the block behaves

exactly like the corresponding Simulink block. The Typecast column

indicates whether the block supports the

Cast output signal to

TargetLink type

feature.
