Real-Time Workshop

1. Analyze the Model

The build process begins with the analysis of your Simulink block diagram. The analysis process consists of these tasks:

• Evaluating simulation and block parameters
• Propagating signal widths and sample times
• Determining the execution order of blocks within the model
• Computing work vector sizes such as those used by S-functions (for more information about work vectors, refer to the Simulink Writing S-Functions documentation.)

During this phase, Real-Time Workshop reads your model file (model.mdl) and compiles an intermediate representation of the model. This intermediate description is stored, in a language-independent format, in the ASCII file model.rtw. The model.rtw file is the input to the next stage of the build process.

model.rtw files are similar in format to Simulink model (.mdl) files. Overview of a model.rtw File explains the basic structure of a .rtw file. For a detailed description of the model.rtw architecture, see model.rtw File Contents in the Target Language Compiler documentation.
