Usage
Name | Description |
---|---|
[-regexp]
|
Patterns are full regular expressions |
[-nocase]
|
Perform case-insensitive matching. (valid only when -regexp specified) |
[-filter]
|
Filter list with expression |
[-of_objects]
|
Get the tiles of these slr, sites, bels, site_pins, bel_pins, nodes, wires, pips, nets, clock_regions. |
[-quiet]
|
Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
[<patterns>]
|
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.
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.
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.
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) Can be used to return the tiles associated with specified sites, bels, site_pins, bel_pins, nodes, wires, pips, nets, clock_regions, or slrs.
-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.
