When a model is running on a target, you can inspect the values of all the variables to see if it is working as it should or to perform measurements. 20-sim 4C provides two ways of inspecting variables: Monitoring and Logging.
•Monitoring: inspect variables at real-time when running.
•Logging: inspect variables off-line.
Monitoring is useful for a quick inspection or to measure slow varying variables. Because the variable values have to be transferred from the target to 20-sim 4C during runtime without disturbing the running model, the refresh rate for monitoring is limited. This means once every few milliseconds a new value will be shown and the values in between are missed. Monitoring is also referred to as signal tracing.
Logging is useful for detailed measurements of all variables. During logging, the values are stored in the target memory. When the logging is stopped or finished, the results are transferred from the target to 20-sim 4C and stored in a file. Logging is also referred to as data acquisition.
