get_filesets - 2020.2 English

Get a list of filesets in the current project

Syntax

get_filesets [‑regexp] [‑nocase] [‑filter <arg>] [‑of_objects <args>]
    [‑quiet] [‑verbose] [<patterns>]

Returns

list of fileset objects

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 'fileset' objects of these types: 'reconfig_module'.
`[-quiet]`	Ignore command errors
`[-verbose]`	Suspend message limits during command execution
`[<patterns>]`	Match fileset names against patterns Default: *

Description

Gets a list of filesets in the current project that match a specified search pattern. The default command gets a list of all filesets in the project.

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_filesets based on property values on the filesets. You can find the properties on an object with the report_property or list_property commands. In the case of the fileset object, "DESIGN_MODE", and "FILESET_TYPE" 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 that may be found in net, pin, or cell names, or other properties. 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) Get the filesets that are associated with the specified reconfig_module objects. The default is to search all filesets.

-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 fileset names against the specified patterns. The default pattern is the wildcard '*' which gets all filesets. More than one pattern can be specified to find filesets based on multiple search criteria.

Examples

The following example returns the source files in the Source Set:

get_files -of_objects [get_filesets sources_1]

The following example makes project_2 the active project, and then gets a list of filesets beginning with the letter s or the letter r:

current_project project_2  
get_filesets s* r* -quiet

Note: If there are no filesets matching the pattern, such as r*, you will get a warning that no filesets matched the specified pattern. However, in the above example the use of -quiet will suppress that warning message.

The following example gets filesets beginning with the letter C, using a case insensitive regular expression:

get_filesets C.* -regexp -nocase

In the above example, constrs_1 and constrs_2 constraint sets would be returned if defined in the current project.
