disconnect_hw_server [‑quiet] [‑verbose] [<hw_server>]


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




Disconnect the current or specified Vivado® tools hardware server from the Vivado® Design Suite.

The current hardware server is either the last connected hardware server, or one you have manually defined with the current_hw_server command. If you disconnect the current hardware server, there will be no defined current hardware server until you define a new current hw_server object.

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_server> - (Optional) The hw_server to disconnect from the Vivado Design Suite. If the server is not specified, the current_hw_server will be disconnected. The hardware server must be specified as a hw_server object returned by the get_hw_servers or current_hw_server commands.


The following example disconnects the specified hardware server from the Vivado Design Suite:
disconnect_hw_server [get_hw_server picasso]
