specification. The generated code accesses this signal as
RT_U.Signal_Name.
- ExportedGlobal — declares the signal as a global variable that can be
accessed from outside the generated code. The signal is declared in the
model package specification but not in the
External_Inputs structure.
The generated code accesses this signal as
Signal_Name. The signal will be
globally visible as
Model.Signal_Name.
- ImportedExtern — the signal is assumed to be declared in the package
specification entered in the
RTW Storage Type Qualifier field. The
generated code accesses this signal as
Your_Package.Signal_Name.
- ImportedExternPointer — this is not permitted in Ada.
•
RTW Storage Type Qualifier — this is only used when specifying the
package specification to qualify fully the signal name for the ImportedExtern
option. This field is ignored in all other cases.
These cases are useful if you want to link Real-Time Workshop Ada Coder
generated code to other Ada code (i.e., code that the Real-Time Workshop Ada
Coder did not generate).
