Description
Gets a list of parameters defined on the current board, as defined in the Board Interface file.
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 parameters defined in the board file specify custom or user-defined characteristics of the board.
This command returns a list of board parameters, 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.
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_parameters
based on property values on the parameter objects. 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 parameter object, "NAME", "VALUE", and "VALUE_TYPE" are some of the properties that can be used to filter results.
get_pins * -filter {DIRECTION == IN && NAME !~ "*RESET*"}
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 parameters of the specified boards, board components, or board component interfaces.
-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.
-verbose
- (Optional) Temporarily override any message limits and return all messages from this command.
set_msg_config
command.<patterns> - (Optional) Match board parameters against the specified search patterns. The default pattern is the wildcard '*' which gets a list of all board parameters defined on the current board.
