A Launch button is provided under the Clocking tab of the System Generator token dialog box to relaunch the Timing Analyzer table using the existing timing analysis results for the model. Make sure the Target directory specified on the Compilation tab of the dialog box is readable by the Timing Analyzer, and the Analyzer Type field is set to Timing. This will only work if you already ran timing analysis on the Simulink model and haven't changed the Simulink model since the last run.
When you click the Launch button, the Timing Analyzer table will display the timing analysis results stored in the specified Target directory, regardless of the option selected for Perform analysis (Post Synthesis or Post Implementation).
You can also launch the Timing Analyzer table to display existing timing analysis results by entering this command at the MATLAB® command prompt:
<mdl_hdle> is the
model handle (the handle of the top level
<netlist_dir> is the Target directory specified in the System Generator token dialog box.
