Syntax

get_nets [-h | -help] [-long_help] [-no_duplicates] [-nocase] [-nowarn] [<filter>]

Arguments

-h | -help	Short help
-long_help	Long help with examples and possible return values
-no_duplicates	Do not match duplicated net names
-nocase	Specifies case-insensitive node name matching
-nowarn	Do not issue warnings messages about unmatched patterns
<filter>	Valid destinations (string patterns are matched using Tcl string matching)

Description

		Returns a collection of nets in the design. All net names in the
		collection match the specified pattern. Wildcards can be used to
		select multiple nets at once.

		The default matching scheme returns nets whose names match the
		specified filter and nets that are automatically generated by the
		Quartus II software from these nets. Use the -no_duplicates option to
		exclude duplicated nets.

		The filter for the collection is a Tcl list of wildcards, and must
		follow standard Tcl or TimeQuest-extension substitution rules.  See
		help for the use_timequest_style_escaping command for details.

Example Usage

# Find a net called "reg" using case insensitive search
get_nets -nocase reg
# Create a collection of all nets whose names start with "reg"
get_nets reg*
# Create a collection of all nets in the design
set mycollection [get_nets *]
# Output net names.
foreach_in_collection net $mycollection {
    puts [get_net_info -name $net]
}

Return Value

Code Name	Code	String Return
TCL_OK	0	INFO: Operation successful
TCL_ERROR	1	ERROR: Timing netlist does not exist. Use create_timing_netlist to create a timing netlist.
