Gets the list of board_part pins object

Syntax

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

Returns

List of pins in the board_part.

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 board_bus_net'.
[-quiet] Ignore command errors
[-verbose] Suspend message limits during command execution
[<patterns>] match board component pin names against patterns Default: * Values: The default search pattern is the wildcard *, or .* when -regexp is specified.

Object, Board

Description

Gets a list of individual board component pins of the specified board component object of the current_board.

The board file, board.xml located in the data/boards folder of the AMD 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).

Board components define the list of components found on the board defined by the Board Interface file. Component pins enumerate the individual pins of the component.

This command returns a list of component pin objects, 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_component_pins based on property values on the component pins. 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 board component pin object, "NAME", "IOSTANDARD", and "PIN_INDEX" are some 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 component pins of the specified board_bus_net, or board_component objects.
Note: The -of_objects option requires objects to be specified using the get_* commands, such as get_cells or get_pins, rather than specifying objects by name. In addition, -of_objects cannot be used with a search <pattern>.
-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 board component pins against the specified search patterns. The default pattern is the wildcard '*' which gets a list of all component pins of the specified objects.

Examples

The following example gets the component pins associated with the specified Xilinx device (part0) component object of the current board:

get_board_component_pins -of_objects [get_board_components *part0*]
