Close a hardware target


close_hw_target [‑quiet] [‑verbose] [<hw_target>]


Name Description
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution
[<hw_target>] hardware target Default: current hardware target




Close the connection to the current or specified hardware target that was previously opened using the open_hw_target command.

The hardware target is a system board containing a JTAG chain of one or more Xilinx® devices that you can program with a bitstream file, or use to debug your design. Connections between hardware targets on the system board and the Vivado® Design Suite are managed by the hw_server application. Refer to Vivado Design Suite User Guide: Programming and Debugging (UG908) for a list of supported JTAG download cables and devices.

This command returns connection messages from the hardware server, 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_target> - (Optional) Specify the hw_target object to close the connection to. The hw_target must be specified as an object as returned by the get_hw_targets or current_hw_target commands. If no target is specified, the open connection to the current_hw_target will be closed.
