Create a new interface port.


create_bd_intf_port [‑vlnv <arg>] [‑mode <arg>] [‑quiet] [‑verbose]


The newly created interface port object, "" if failed.


Name Description
[-vlnv] Bus vlnv
[-mode] Bus interface mode
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution
[<name>] Name of port to create




Create a new IP integrator subsystem design interface port. An IP integrator interface is a grouping of signals that share a common function, and can include both individual signals and buses that share a related function. An AXI4-Lite master, for example, is an interface that includes a large number of individual signals plus multiple buses.

To create a single connection port, or common bus port, use the create_bd_port command.

This command returns the name of the newly created interface port object if successful, and returns nothing if it failed.


-vlnv <arg> - (Optional) The Vendor:Library:Name:Version (VLNV) attribute of the interface port object to be added to the subsystem design. The VLNV attribute identifies the object in the IP integrator catalog.

Note: The -vlnv property for interface pins and ports refers to files in the Vivado™ Design Suite installation hierarchy that can be found in the ./data/ip/interfaces directory. -vlnv, for example, is located in the Vivado Design Suite installation at data/ip/interfaces/lmb_v1_0.

-mode <arg> - (Optional) Defines the mode of the interface pin. Accepted values are Master, Slave, System, MirroredMaster, MirroredSlave, MirroredSystem, Monitor.

-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.

<name> - (Required) The name of the interface port to add to the subsystem design.


The following example creates a new IP integrator interface port and adds it to the current subsystem design:

create_bd_intf_port -vlnv \
   -mode Slave diff_clock_rtl
