Target Language Compiler Architecture

System Target Files

Table 3-1 lists the system target files that generate the RTW code.

Note: The grt.tlc file is in the /MATLAB/rtw/c/grt directory. All the system,

library, and block target files referred to in this section are in the

/MATLAB/rtw/c/tlc directory.

To generate all of the associated generic real-time RTW code, you execute:

tlc –r model.rtw MATLAB/rtw/c/grt/grt.tlc –IMATLAB/rtw/c/tlc

As the names suggest, mdlhdr.tlc creates the model’s header file model.h,

mdlparam.tlc creates the model’s parameters file model.prm, mdlreg.tlc

creates the model’s function registration file, and

mdlbody.tlc creates the

model’s source code file

model.c. If the code size in model.c reaches the file size

threshold, code generation continues in

model1.c. This process continues in

model2.c, and so on.

System Target File Purpose

grt.tlc

Assigns specific variables required for generic

real-time code generation, and is the Target

Language Compiler entry point.

mdlwide.tlc

Assigns more generalized variables required for

RTW code generation, and is included by

grt.tlc.

mdlbody.tlc

Included by mdlwide.tlc.

mdlreg.tlc

Included by mdlbody.tlc.

mdlhdr.tlc

Included by mdlreg.tlc.

mdlparam.tlc

Included by mdlreg.tlc.
