Connect port and pin object list.
Syntax
connect_bd_net [‑net <arg>] [‑boundary_type <arg>] [‑quiet] [‑verbose]
<objects>...
Returns
TCL_OK, TCL_ERROR if failed.
Usage
Name | Description |
---|---|
[-net]
|
The single net that all objects connect to |
[-boundary_type]
|
Used when source object is on a hierarchical block's pin. Valid values are 'upper', 'lower', or 'both'. If 'lower' boundary, searches from the lower level of hierarchy onwards. Default: both |
[-quiet]
|
Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
<objects>
|
The objects connect to the net |

Description
Create a new net in the current IP integrator subsystem design connecting the specified list of block diagram port and pin objects, or connect an existing net to the specified pins and ports.
If the -net
option is not specified, a new net is created connecting the listed objects. If -net
is used, the specified net is either connected or created as needed.
Use the get_bd_ports
and get_bd_pins
commands to specify the port and pin objects to connect.
You can use this command to connect pins or ports at different levels of the subsystem design hierarchy. However, in this case, you cannot specify the -net
option because the connection, when complete, will result in multiple nets rather than a single net.
The command returns the connected IP integrator subsystem design net object, or returns an error.
Arguments
-net <arg>
- (Optional) Create a single net in the current IP subsystem design.
-net
argument is optional. When the objects being connected are not in the same level of hierarchy, the net argument should not be specified.
-boundary_type [ lower | upper | both ]
- (Optional) Specifies the search area for making a connection to a pin of an hierarchical block. The default of both
searches the current level of the block design hierarchy, and downward, to find connecting objects. Specify upper
to search only the current level of hierarchy, specify lower
to search from the bottom of the hierarchy upward.
-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.
<objects>
- Connect the specified list of port and pin objects in the current IP integrator subsystem design.
Examples
connect_bd_net [get_bd_pins /vidOut_1/locked] \
[get_bd_pins /newMod1/bridge_1/fid]
-net
option is not specified. In this case, multiple nets are created for connection across the hierarchy.
