|
filters <patterns> according to the specified property-matching expressions |

|
Suspend message limits during command execution |
[<patterns>]
|
the pattern strings to search for wave configuration names |

Description
Get the wave configuration objects that match the specified search options in the current simulation.
In the Vivado® simulator GUI, you can work with a waveform to analyze your design and debug your code. The Wave Config file contains the list of wave objects (signals, dividers, groups, virtual buses) to display, and their display properties, plus markers. A wave configuration displays with top-level HDL objects, and can be further populated using commands like add_wave
and add_wave_divider
.
This command returns the matching wave configuration objects, or returns nothing if no objects matched the search pattern.
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 get_wave_configs
based on property values on the wave configuration objects. You can find the properties on an object with the report_property
or list_property
commands. In the case of the "Wave Configuration" object, "NAME", "NEEDS_SAVE", and "FILE_PATH" are some of the properties that can be used to filter results.
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 wave configuration objects in the current simulation against the specified search patterns. The default pattern is the wildcard '*' which gets a list of all open wave configurations in the simulation.
Examples
The following example returns all wave configuration objects, in the current simulation, that have unsaved changes:
get_wave_config -filter {NEEDS_SAVE}
