Description

Disconnect a single interface net in the IP integrator subsystem design from the specified objects. An interface is a grouping of signals that share a common function in the IP integrator subsystem design.

This command lets you disconnect the specified interface net from pins or ports in the IP subsystem design, without deleting the whole net. To delete the whole net, you should use the delete_bd_objs command.

This command returns TCL_OK if it is successful, or TCL_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.
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.

<intf_net> - (Required) Specifies a single interface net in the IP subsystem design to disconnect from the specified objects. The net can be specified by name, or as a single object returned by the get_bd_intf_nets command.

<objects> - (Required) The list of interface pin or port objects to disconnect the net from. The interface pins and ports must be specified as design objects returned by the get_bd_intf_pins or get_bd_intf_ports commands. They cannot simply be referenced by name.

Example

The following example disconnects the only interface net in the IP subsystem design, from all interface pin and port objects that are connected to it: 
disconnect_bd_intf_net [get_bd_intf_nets] \  
[get_bd_intf_pins -of_objects [get_bd_intf_nets]] \  
[get_bd_intf_ports -of_objects [get_bd_intf_nets]]
Note: In this example you know there is only one interface net in the design, or an error would be returned by the disconnect_bd_intf_net command, which only accepts a single interface net.
