[-verbose] Suspend message limits during command execution
<port> Debug port name




Disconnect signals from the debug ports.

Signals from the Netlist Design are connected to ports of a ILA debug core using the connect_debug_port command.

A port can also be deleted from the debug core rather than simply disconnected by using the delete_debug_port command.

If you need to determine the specific name of a port on a debug core, use the get_debug_ports command to list all ports on a core. You can also use the report_debug_core command to list all of the cores in the projects, and their specific parameters.


-channel_index <value> - (Optional) The channel index of the port to disconnect.

Note: The entire port is disconnected if -channel_index is not specified.

<port> - (Required) The name of the port on the debug core to disconnect. The port name must be specified as core_name/port_name. See the examples below.

-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.


The following example disconnects only the specified channel index from the PROBE1 port of myCore:

disconnect_debug_port -channel_index 2 myCore/PROBE1

If you do not specify the channel_index, all of the channels of the specified port will be disconnected, as in the following example:

disconnect_debug_port myCore/PROBE1
