Description
Update the INPUT_VALUE and ACTIVITY_VALUE properties of the input probes of the specified VIO debug cores with values read from the hw_vio core on the hardware device.
The Virtual Input/Output (VIO) debug core can both monitor and drive internal signals on a programmed Xilinx device in real time. The VIO core uses hardware probes, hw_probe objects, to monitor and drive signals on the device. Input probes monitor signals as inputs to the VIO core. Output probes drive signals to specified values from the VIO core.
The refresh_hw_vio command reads the signal values at the input probes of the VIO debug core on the device, and applies the value to the INPUT_VALUE property of the hw_probe, and updates the ACTIVITY_VALUE property on the probe as well.
This command returns nothing if successful, or returns an error if it fails.
Arguments
-update_output_values - (Optional) Update hardware probe OUTPUT_VALUE property with values read from the signals at the specified VIO debug cores. This is a boolean argument enabled by its presence. This option has the affect of resetting the OUTPUT_VALUE on the probe to match the signal value on the hw_vio debug core.
commit_hw_vio command, which applies the OUTPUT_VALUE on the probe to the hw_vio debug core on the device.-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.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
set_msg_config command.<hw_vios> - (Required) Specify one or more hw_vio objects to refresh. The hw_vio objects can either be specified as objects returned by the get_hw_vios command, or specified by name.
Example
refresh_hw_vio -update_output_values hw_vio_1
