Real-Time Workshop User's Guide

Code Generation and the Build Process

Introduction

This chapter continues the discussion of code generation and the build process, introduced in Chapter 2, Technical Overview. Topics covered in detail include:

• Overview of the Real-Time Workshop User Interface introduces the features controlled by the Real-Time Workshop pageof the Simulation Parameters dialog.

The sections that follow concern the code generation phase of the build process.

• Simulation Parameters and Code Generation discusses how options on the Simulink Solver, Workspace I/O, Diagnostics, and Advanced pages interact with code generation. These options include choice of single- or multitasking execution, and several methods of logging data to MAT-files. The section also illustrates how to trace back from to the blocks that generated the code.

The section ends with a discussion of Other Interactions Between Simulink and the Real-Time Workshop such as sample time propagation and order of execution of blocks.

• Selecting a Target Configuration illustrates the use of the System Target File Browser, and summarizes the target configurations that you can access through the browser.
• Nonvirtual Subsystem Code Generation describes generation of separate code modules from nonvirtual subsystems.
• Generating Code and Executables from Subsystems describes how to generate and build a stand-alone executable from a subsystem.
• Parameters: Storage, Interfacing, and Tuning documents how to generate storage declarations in order to export and import model parameters to and from user-written code.
• Signals: Storage, Optimization, and Interfacing documents how signal storage optimizations work, and how to generate storage declarations in order to export and import model signals to and from user-written code.
• Simulink Data Objects and Code Generation documents how to represent and store signals and parameters in Simulink data objects, and how code is generated from these object.

The remaining sections cover the make (post-code generation) part of the build process:

• Making an Executable documents options that control whether or not an executable is created during the build process.
• Directories Used in the Build Process documents the output directories used and/or created during the build process.
• Choosing and Configuring Your Compiler discusses the installation of a compiler and choice of a template makefile appropriate for use with your compiler.
• Template Makefiles and Make Options includes a summary of available template makefiles and make command options.
