TLC Debugging Options

The TLC Debugging options are of interest to those who are writing TLC code when customizing targets, integrating legacy code, or developing new blocks. These options are summarized here; refer to the Target Language Compiler documentation for details. The TLC Debugging options are

• Retain .rtw file

• Normally, the build process deletes the model.rtw file from the build directory at the end of the build. When Retain .rtw file is selected, model.rtw is not deleted. This option is useful if you are modifying the target files, in which case you will need to look at the model.rtw file.

• Profile TLC

• When this option is selected, the TLC profiler analyzes the performance of TLC code executed during code generation, and generates a report. The report is in HTML format and can be read by your Web browser.

• Start TLC debugger when generating code

• This option starts the TLC debugger during code generation.

  You can also invoke the TLC debugger by entering the -dc argument into the System Target File field on the Real-Time Workshop pane.

  To invoke the debugger and run a debugger script, enter -df filename into the System Target File field on the Real-Time Workshop pane.

• Start TLC coverage when generating code

• When this option is selected, the Target Language Compiler generates a report containing statistics indicating how many times each line of TLC code is hit during code generation.

  This option is equivalent to entering the -dg argument into the System Target File field on the Real-Time Workshop pane.

• Enable TLC Assertions

• When this box is selected, Real-Time Workshop will halt building if any user-supplied TLC file contain an %assert directive that evaluates to FALSE. The box is not selected by default, meaning that TLC assertion code will be ignored. You may also use these MATLAB commands to control TLC assertion handling:

  set_param(model, 'TLCAssertion', 'on|off') to set this flag on or off. Default is Off.

  get_param(model, 'TLCAssertion') to see the current setting.
