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 Log	Write signal data file log on target computer (Since R2020b)
Enable File Log	Enable or disable file logging of signals on target computer (Since R2020b)
Enable Profiler	Start and stop execution profiler on target computer (Since R2020b)
Log Event	Log an execution profiling event (Since R2020b)

Objects

`Target`	Represent real-time application and target computer status (Since R2020b)
`Target.FileLog`	Target Computer file logger (Since R2020b)
`Targets`	Configure and manage target objects (Since R2020b)
`ProfilerData`	Data returned from profiler (Since R2020b)
`Instrument`	Create real-time instrument object (Since R2020b)
`slrealtime.instrument.LineStyle`	Create 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.
