Sample ERT-Based Model with Subsystem

The next figure shows an ERT-based Simulink model that defines one subsystem, and the contents of that subsystem.

Assume that the subsystem is atomic, the Real-Time Workshop system code is Reusable function, memory sections have been created and assigned as shown in the next two tables, and all data memory sections specify Pragma surrounds to be Each variable.

Model-Level Memory Section Assignments and Definitions

Section Assignment	Section Name	Field Name	Field Value
Input/Output	MemSect1	Prepragma	#pragma IO_begin
		Postpragma	#pragma IO-end
Internal data	MemSect2	Prepragma	#pragma InData-begin(%<identifier>)
		Postpragma	#pragma InData-end
Parameters	MemSect3	Prepragma	#pragma Parameters-begin
		Postpragma	#pragma Parameters-end
Initialize/ Terminate	MemSect4	Prepragma	#pragma InitTerminate-begin
		Postpragma	#pragma InitTerminate-end
Execution functions	MemSect5	Prepragma	#pragma ExecFunc-begin(%<identifier>)
		Postpragma	#pragma ExecFunc-begin(%<identifier>)

Subsystem-Level Memory Section Assignments and Definitions

Section Assignment	Section Name	Field Name	Field Value
Execution functions	MemSect6	Prepragma	#pragma DATA_SEC(%<identifier>, "FAST_RAM")
		Postpragma

Given the preceding specifications and definitions, the code generator would create the following code, with minor variations depending on the current version of the Target Language Compiler.
