Get a list of Library Cell Pins
Syntax
get_lib_pins [‑regexp] [‑filter <arg>] [‑nocase] [‑of_objects <args>]
[‑quiet] [‑verbose] <patterns>
Returns
List of library cell pins.
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. |
[-of_objects]
|
Get the library cell pins of the objects passed in here. Valid objects are cells or instances (ie, get_cells), cell pins (ie, get_pins) and library cells (ie get_lib_cells). |
[-quiet]
|
Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
<patterns>
|
Match library cell pin names against patterns of the form <library cell pattern>/<library pin pattern>. |

Description
Gets a list of the pins on a specified cell of the cell library for the target part in the current design.
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_lib_pins
based on property values on the pins. 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}
-of_objects <arg>
- (Optional) Get a list of library cell pins of the specified cells, library cells, or pin objects.
-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> - (Required) Match lib pins against the specified patterns. The pattern must specify the library name, cell name, and the pins.
