Logging and Profiling

Simulation Data Inspector, Simulink Scope blocks, File Log blocks, target computer access, profiling

To observe the behavior of your real-time application and the target computer on which it is running, use logging and profiling blocks.

Blocks

File LogWrite signal data file log on target computer (Since R2020b)
Enable File LogEnable or disable file logging of signals on target computer (Since R2020b)
Enable ProfilerStart and stop execution profiler on target computer (Since R2020b)
Log EventLog an execution profiling event (Since R2020b)

Objects

TargetRepresent real-time application and target computer status (Since R2020b)
Target.FileLogTarget Computer file logger (Since R2020b)
TargetsConfigure and manage target objects (Since R2020b)
ProfilerDataData returned from profiler (Since R2020b)
InstrumentCreate real-time instrument object (Since R2020b)
slrealtime.instrument.LineStyleCreate real-time instrument LineStyle object (Since R2022b)

Troubleshooting

Troubleshoot Signal Data Logging from Nonvirtual Bus, Fixed-Point, and Multidimensional Signals

Investigate issues that can occur when signal data logging from signals in nonvirtual buses, signals with fixed-point data type, and multidimensional signals.

Troubleshoot Signal Data Logging from Inport in Referenced Model

Investigate issues that prevent some signals from streaming to the Simulation Data Inspector.

Troubleshoot Signal Data Logging from Inport in Referenced Model in Test Harness

Investigate issues that can occur when signal data logging from signals in referenced models in test harnesses.

Troubleshoot Signal Data Logging from Send and Receive Blocks

Investigate issues that can occur when signal data logging from Send and Receive blocks.

Troubleshoot Signals for Streaming or File Logging

Investigate issues related to an error that a signal cannot be streamed or logged.
