Usage
Name | Description |
---|---|
[-of_objects]
|
Get 'rule_check' objects of these types: 'drc_ruledeck'. |
[-regexp]
|
Patterns are full regular expressions |
[-nocase]
|
Perform case-insensitive matching. (valid only when -regexp specified) |
[-filter]
|
Filter list with expression |
[-abbrev]
|
Get the largest ID for this abbrev |
[-ruledecks]
|
Containers of Report DRC rule checks Default: default |
[-quiet]
|
Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
[<patterns>]
|
Match the 'rule_check' objects against patterns. Default: * |
Description
Gets a list of the currently defined DRC checks. This list includes both factory defined design rule checks, and user-defined checks created by the create_drc_check
command.
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
-of_objects
<args> - (Optional) Get the design rule checks associated with a rule deck object. The ruledeck object must be specified by the get_drc_ruledecks
command.
-of_objects
cannot be used with a search <pattern>
.-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 rule checks returned by get_drc_checks
based on property values on the rule checks. 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}
-abbrev <arg>
- (Optional) Get the design rule checks associated with the specified rule name or abbreviation.
-ruledecks
<args> - (Optional) Get the design rule checks associated with the specified rule decks.
-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.
