[<patterns>]
Returns
Drc_ruledeck
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 the 'drc_ruledeck' objects against patterns. Default: * |
Description
Delete one or more user-defined drc_ruledeck objects from the current project. The rule deck does not have to be empty to be deleted, and once it is deleted there is no way to recover it. The undo
command will not restore a deleted rule deck.
A rule deck is a collection of design rule checks grouped for convenience, to be run with the report_drc
command at different stages of the FPGA design flow, such as during I/O planning or placement. The tool comes with a set of factory defined rule decks, but you can also create new user-defined rule decks with the create_drc_ruledeck
command.
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 the search pattern, based on specified property values. 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) Delete the drc_ruledeck objects that match the specified patterns. The default pattern is the wildcard '*' which deletes all user-defined rule decks from the current project. More than one pattern can be specified to delete multiple rule decks based on different search criteria.
Examples
The following example deletes all user-defined rule decks from the current project:
