Profiling and Optimization

Execution profiling, display, analysis, and optimization by using MATLAB^® functions

Profile the task execution time and function execution time of the real-time application that is running on the target computer. Then, you can tune its performance.

Objects

`Target`	Represent real-time application and target computer status (Since R2020b)
`Instrument`	Create real-time instrument object (Since R2020b)
`slrealtime.instrument.LineStyle`	Create real-time instrument LineStyle object (Since R2022b)
`ProfilerData`	Data returned from profiler (Since R2020b)
`Stimulation`	Target computer model root inport stimulator object (Since R2021a)

Functions

`startProfiler`	Start profiling service on target computer (Since R2020b)
`stopProfiler`	Stop profiling service on target computer (Since R2020b)
`getProfilerData`	Retrieve profile data object (Since R2020b)
`resetProfiler`	Reset profiling service state to `Ready` (Since R2020b)
`slrtTETMonitor`	Open Simulink Real-Time task execution time (TET) monitor (Since R2020b)
`plot`	Generate execution profiler plot (Since R2020b)
`report`	Generate profiler report (Since R2020b)
`getSupportInfo`	Creates `slrealtimeinfo.txt` file that provides support information about Simulink Real-Time installation (Since R2020b)
`getCrashStack`	Downloads and decodes crash stack core files from target computer and opens these in MATLAB editor (Since R2020b)

Blocks

Enable Profiler	Start and stop execution profiler on target computer (Since R2020b)
Log Event	Log an execution profiling event (Since R2020b)
