Syntax

get_board_part_interfaces [‑regexp] [‑nocase] [‑filter <arg>]
    [‑of_objects <args>] [‑quiet] [‑verbose] [<patterns>...]

Returns

List of bus interfaces.

Usage

Name	Description
`[-regexp]`	Patterns are full regular expressions
`[-nocase]`	Perform case-insensitive matching
`[-filter]`	Filter list with expression
`[-of_objects]`	Get 'board_component_interface' objects of these types: 'board board_component'.
`[-quiet]`	Ignore command errors
`[-verbose]`	Suspend message limits during command execution
`[<patterns>]`	Match Bus Interface names against patterns Default: * Values: The default search pattern is the wildcard , or . when -regexp is specified.

Description

Gets a list of interfaces defined on the Xilinx device, or current board part as defined by the BOARD_PART property, on the board in use by the current project or open design.

The board file, board.xml located in the data/boards folder of the Vivado Design Suite installation area, stores information regarding board attributes. The board provides a representation of the overall system that the Xilinx device is a part of, and can help define key aspects of the design, such as clock constraints, I/O port assignments, and supported interfaces. You can create custom boards by defining a custom Board Interface file, as described in the Vivado Design Suite User Guide: System-Level Design Entry (UG895).

The board part provides a representation of the Xilinx device in the context of the board-level system, and is represented by the part0 component in the Board Interface file. The current_board_part command returns the board part in use by the current project.

The interfaces defined on the current board part define related groups of signals that can be used to quickly connect the elements of a block design in Vivado IP integrator, or configure IP from the Xilinx IP catalog. The interfaces available on the current_board_part can be used to define the interfaces required in an IP subsystem design, using create_bd_interface_port or create_bd_port. It can also be used to define the interfaces available in the overall FPGA design using create_interface and create_port.

This command returns a list of available interfaces on the current board part, or returns an error if it fails.

Arguments

-regexp - (Optional) Specifies that the search <patterns> are written as regular expressions. Both search <patterns> and -filter expressions must be written as regular expressions when this argument is used. Xilinx regular expression Tcl commands are always anchored to the start of the search string. You can add ".*" to the beginning or end of a search string to widen the search to include a substring. See http://perldoc.perl.org/perlre.html for help with regular expression syntax.

Note: The Tcl built-in command regexp is not anchored, and works as a standard Tcl command. For more information refer to http://www.tcl.tk/man/tcl8.5/TclCmd/regexp.htm.

-nocase - (Optional) Perform case-insensitive matching when a pattern has been specified. This argument applies to the use of -regexp only.

-filter <args> - (Optional) Filter the results list with the specified expression. The -filter argument filters the list of objects returned by get_board_part_interfaces based on property values on the interfaces. You can find the properties on an object with the report_property or list_property commands. For example:

report_property -all [get_board_part_interfaces ddr3*]

The filter search pattern should be quoted to avoid having to escape special characters. String matching is case-sensitive and is always anchored to the start and to the end of the search string. The wildcard “*” character can be used at the beginning or at the end of a search string to widen the search to include a substring of the property value.

Note: The filter returns an object if a specified property exists on the object, and the specified pattern matches the property value on the object. In the case of the "*" wildcard character, this will match a property with a defined value of "".

For string comparison, the specific operators that can be used in filter expressions are "equal" (==), "not-equal" (!=), "match" (=~), and "not-match" (!~). Numeric comparison operators <, >, <=, and >= can also be used. Multiple filter expressions can be joined by AND and OR (&& and ||). The following gets input pins that do NOT contain the “RESET” substring within their name:

get_pins * -filter {DIRECTION == IN && NAME !~ "*RESET*"}

Boolean (bool) type properties can be directly evaluated in filter expressions as true or not true:

-filter {IS_PRIMITIVE && !IS_LOC_FIXED}

-of_objects <args> - (Optional) Get the interfaces of the specified board objects, as returned by the get_boards command, or board components as returned by get_board_components.

-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.

<patterns> - (Optional) Match available board part interfaces against the specified search patterns. The default pattern is the wildcard '*' which gets a list of all interfaces available for use in the current project or design. More than one pattern can be specified to find multiple interfaces based on different search criteria.

Note: You must enclose multiple search patterns in braces, {}, or quotes, "", to present the list as a single element.

Examples

The following example gets a list of all interfaces defined on the current board part:

join [get_board_part_interfaces] \n
