Gets the list of interface ports object

Syntax

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

Returns

List of ports in the given interface.

Usage

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

Object, Board

Description

Gets a list of various physical ports assigned to the component interfaces defined on the current board, as defined in the Board Interface file. The interface ports can be returned from component interfaces as specified by the get_board_component_interfaces command, or from the component pins returned by get_board_component_pins.

The Board Interface 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 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).

In the Board Interface file, a component interface includes a map of the logical ports, that are defined in the interface file, with a physical port that relates to the component pin or pins on the Xilinx device (part0).

This command returns a list of the physical ports of the specified component interface, 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 - (Optional) Filter the results list with the specified expression. The -filter argument filters the list of objects returned by get_board_interface_ports based on property values on the interface ports. You can find the properties on an object with the report_property or list_property commands. Any property/value pair can be used as a filter. In the case of the interface port object, "LOGICAL_NAME" and "DIRECTION" are two of the properties that can be used to filter results.

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> - (Required) Get the physical interface ports of the specified board component interface, or board component pin objects.

-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 physical interface ports against the specified search patterns. The default pattern is the wildcard '*' which gets a list of all component interface ports defined on the specified object.

Examples

The following example gets the board interface ports defined in the Board Interface file for the specified board component:

get_board_interface_ports -of_objects \
   [get_board_component_interfaces *gmii*]
