Description
Reset the hardware VIO debug core outputs to their initial, or "reset" state.
The Virtual Input/Output (VIO) debug core can both monitor and drive internal signals on a programmed AMD FPGA 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 reset_hw_vio_outputs
command restores the signal values at the output probes of the specified hw_vio debug cores to their initial values. This affects the signal on the hw_device, but does not affect the OUTPUT_VALUE property of the hw_probe objects.
This command returns nothing if successful, or returns an error if it fails.
Arguments
-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 reset. The hw_vio objects can either be specified as objects returned by the get_hw_vios
command, or specified by name.
Example
The following example resets the output probes on the VIO debug core to the initial values on the core when the FPGA was first configured and booted:
reset_hw_vio_outputs [get_hw_vios {hw_vio_1}]
