get_methodology_violations [‑name <arg>] [‑regexp] [‑filter <arg>]
[‑nocase] [‑quiet] [‑verbose] [<patterns>]
Returns
List of Methodology violation objects.
Usage
Name | Description |
---|---|
[-name]
|
Get the results with this name |
[-regexp]
|
Patterns are full regular expressions |
[-filter]
|
Filter list with expression |
[-nocase]
|
Perform case-insensitive matching (valid only when -regexp specified) |
[-quiet]
|
Ignore command errors |
[-verbose]
|
Suspend message limits during command execution |
[<patterns>]
|
Match methodology_violations against patterns Default: * Values: The default search pattern is the wildcard *, or .* when -regexp is specified. |

Description
Gets a list of violation objects found in the design when the report_methodology
command is run. The properties of individual violation objects can be queried using report_property
or list_property
commands for details of the violation.
Violation objects are associated with the cells, nets, pins, or ports in the current design, or sites on the current device. The design objects associated with a methodology violation object can be obtained using the -of_objects
option of the appropriate get_*
command, such as get_cells
, or get_nets
for instance.
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
-name <arg>
- (Optional) Get the violations associated with the named methodology result set. In this case the report_methodology
command must also have been run with the -name
option.
-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 get_methodology_violations
based on property values on the violations. 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) Match violations against the specified patterns. The default pattern is the wildcard '*' which gets all violations. More than one pattern can be specified to find multiple violations based on different search criteria.
Examples
The following example reports the methodology violations found in the current design, then returns a list of all those violations:
report_methodology
get_methodology_violations
The following example generates list of violations in the named methodology report, and then gets the pins associated with any violations found:
report_methodology -name method_1
get_pins -of_objects [get_methodology_violations -name method_1]
