get_reconfig_modules - 2020.2 English

Get a list of ReconfigModules

Syntax

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

Returns

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

Description

Get a list of reconfigurable modules (RMs) in the current design that match a specified search pattern. The default command returns a list of all RMs in the current project.

This command returns a list of RM 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_reconfig_modules based on property values on the RMs. You can find the properties on an object with the report_property or list_property commands. In the case of the "RM" object, "IS_GATE_LEVEL" and "PARTITION_DEF" are two 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 <arg> - (Optional) Get the reconfig_modules of specified partition_def objects.

-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 reconfigurable modules (RMs) against the specified search pattern. The default pattern is the wildcard '*' which gets a list of all RMs in the project.

Example

The following example gets all gate level, or netlist-based RMs in the project:

get_reconfig_modules -filter {IS_GATE_LEVEL}
