Syntax

get_pr_configurations [‑regexp] [‑nocase] [‑filter <arg>] [‑quiet]
    [‑verbose] [<patterns>]

Returns

list of Configuration 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
`[-quiet]`	Ignore command errors
`[-verbose]`	Suspend message limits during command execution
`[<patterns>]`	Match partition configuration names against patterns Default: *

Description

Get a list of PR configuration objects in the current project.

In the Partial Reconfiguration (PR) design flow, the PR configuration lets you specify a reconfigurable module (RM) to assign to a specific instance of a Partition Definition (partitionDef). This flow lets you create unique configurations of the design based on the combination of the core design and one or more RMs. The PR design flow requires the implementation of each PR configuration, resulting in partial bitstreams for the RMs, but complete bitstreams for each integrated configuration. Refer to the Vivado Design Suite User Guide: Dynamic Function eXchange (UG909) for more information.

This command returns a list of PR configuration objects, or returns an error if the command fails.

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_pr_configurations based on property values on the configurations. You can find the properties on an object with the report_property or list_property commands.

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}

-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 PR configurations against the specified search pattern. The default pattern is the wildcard '*' which gets a list of all PR configurations in the project.

Example

The following example gets all of the PR configuration objects in the project:
