Reset hardware VIO ACTIVITY_VALUE properties, for hardware probes associated with specified hardware VIO objects.


reset_hw_vio_activity [‑quiet] [‑verbose] <hw_vios>...


Name Description
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution
<hw_vios> List of hardware VIO objects.




Resets the ACTIVITY_VALUE properties for all hardware probes on the specified VIO debug core objects. The ACTIVITY_VALUE property is used by the Vivado® IDE to represent transitions on the input probes of the VIO debug cores.

In addition to reading values from the VIO input probes, you can also monitor the activity of the VIO input probes. The ACTIVITY_VALUE property is used to indicate when the values on the VIO inputs have changed in between periodic updates to the Vivado IDE. Refer to the Vivado Design Suite User Guide: Programming and Debugging (UG908) for more information.

This command returns nothing if successful, or returns an error if it fails.


-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.

<hw_vios> - (Required) Specify one or more hw_vio objects to reset. The hw_vio objects can either be specified as objects returned by the get_hw_vios command, or specified by name.


The following example resets the input activity properties of the VIO debug core:
