The model.rtw File
Real-Time Workshop generates a model.rtw file from your Simulink model. 
The 
model.rtw file is a hierarchical database whose contents provide a 
description of the individual blocks within the Simulink model.
model.rtw is an ASCII file of parameter-value pairs stored in a hierarchy of 
records defined by your model. A parameter-value pair is specified as:
ParameterName value
where ParameterName, (also called an identifier) is the name of the RTW 
identifier and 
value is a string, scalar, vector, or matrix. For example, in the 
parameter-value pair
.
.
NumDataOutputPorts 1
.
.
NumDataOutputPorts
 is the identifier and 1 is its value.
A record is specified as:
RecordName {
.
.
}
A record contains parameter-value pairs and/or subrecords. For example, this 
record contains one parameter-value pair:
DataStores {
 NumDataStores  0
}
The following reduced example shows a record, Block, with several 
parameter-value pairs (
Type, Name, Identifier, and so on), and three 
subrecords, each called 
Parameter. Block is a subrecord of System, which is a 
subrecord of 
CompiledModel.
