Description

Create a new group to associate the specified TX to RX communication links on the IBERT debug core implemented on the current device.

Vivado® Serial I/O analyzer is a link-based analyzer. The links define the communication paths and protocols between transmitters and receivers of the GigaBit transceivers on the device. Link groups, or hw_sio_linkgroup objects, let you associate links into related groups, to collectively configure properties and run scans.

This command returns the name of the linkgroup created, or returns an error if the command fails.

Arguments

-description <arg> - (Optional) Provide a brief description that acts as a label for the link group. This description is stored on the DESCRIPTION property of the hw_sio_linkgroup object.

-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_sio_links> - (Required) Specify one or more hw_sio_link objects to associate together as a group. The hw_sio_links must be specified as objects as returned by the create_hw_sio_link or get_hw_sio_links commands.

Note: If you include a hw_sio_link object that already belongs to another linkgroup, the command will return an error.

Example

The following example uses the DESCRIPTION property on hw_sio_link objects to identify which links to add to a new link group:

create_hw_sio_linkgroup -description "LoopBack Links" \
   [get_hw_sio_links -filter {DESCRIPTION == Link_12 || DESCRIPTION == \
   "Link 9" || DESCRIPTION == "Link 10" || DESCRIPTION == "Link 11" }]
