Get a list of Libraries
Syntax
get_libs [‑regexp] [‑filter <arg>] [‑nocase] [‑quiet] [‑verbose]
[<patterns>]
Returns
List of libraries.
Usage
Name | Description |
---|---|
[-regexp]
|
Patterns are regular expressions |
[-filter]
|
Filter list with expression |
[-nocase]
|
Perform case-insensitive matching when a pattern has been specified. This argument applies to the use of -regexp only. |
[-quiet]
|
Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
[<patterns>]
|
Match library names against patterns. Default: * |

Description
Gets the cell library for the target device in the current design. There is a library for each device family because there are primitives that may be available in one device family but not in others.
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_libs
based on property values on the objects. You can find the properties on an object with the report_property
or list_property
commands.
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}
-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 libraries against the specified patterns. The default pattern is the wildcard '*' which gets a list of all libraries in the project.
Examples
The following example gets the cell library for the target part:
