- ImportedExtern — the variable is assumed to be declared in the package
specification entered in the
Storage Type Qualifier field. The generated
code accesses this variable as
Your_Package.Your_variable.
- ImportedExternPointer — this is not permitted in Ada.
•
Storage Type Qualifier — this is only used when specifying the package
specification to qualify fully the variable 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 generated
code to other Ada code (that is, code that the Real-Time Workshop did not
generate)
Signal Properties
The Real-Time Workshop Ada Coder supports the same storage class options
for signals as it does for parameters. It has heuristics for supporting Simulink
signal labels. These heuristics automatically map signal labels to Simulink
blocks based on the block name, signal name, and connectivity. You can
override the default behavior and either specify an external declaration for the
signal name or direct the Real-Time Workshop Ada Coder to declare a unique
declaration of the signal that is visible in the generated model package
specification. The heuristics are implemented on a signal basis as specified by
the
Signal name, RTW Storage Class,andRTW Storage Type Qualifier
(externally declared signals only).
