Match tiles against patterns Default: * |
Description
This command returns a list of tiles on the device in an open design. The default command gets a list of all tiles on the device.
Note: To improve memory and performance, the
get_* commands return a container list of a single type of objects (e.g. cells, nets, pins, or ports). You can add new objects to the list (using lappend for instance), but you can only add the same type of object that is currently in the list. Adding a different type of object, or string, to the list is not permitted and will result in a Tcl error.
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_tiles based on property values on the tile 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 tile object, "NUM_ARCS", "NUM_SITES", and "IS_GT_SITE_TILE" 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> - (Optional) Can be used to return the tiles associated with specified sites, bels, site_pins, bel_pins, nodes, wires, pips, nets, clock_regions, or slrs.
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 tiles against the specified patterns. The default pattern is the wildcard '*' which gets a list of all tiles on the device. More than one search pattern can be specified to find tiles 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 returns the total number of tiles where the number of timing arcs is greater than 100 and 150 respectively:
llength [get_tiles -filter {NUM_ARCS>100} ]
13468
llength [get_tiles -filter {NUM_ARCS>150} ]
11691
