3.1.27.11. get_pins (::quartus::sdc)

The following table displays information for the get_pins Tcl command:

Tcl Package and Version	Belongs to ::quartus::sdc
Syntax	`get_pins [-h \| -help] [-long_help]` `[-compatibility_mode]` `[-hierarchical]` `[-no_duplicates]` `[-nocase]` `[-nowarn]` `[` <filter> `]`
Arguments	`-h \| -help`		Short help
	`-long_help`		Long help with examples and possible return values
	`-compatibility_mode`		Use simple Tcl matching
	`-hierarchical`		Specifies use of a hierarchical searching method
	`-no_duplicates`		Do not match duplicated pin names
	`-nocase`		Specifies case-insensitive node name matching
	`-nowarn`		Do not issue warning messages about unmatched patterns
	<filter>		Valid destinations (string patterns are matched using Tcl string matching)
Description	Returns a collection of pins in the design. All pin names in the collection match the specified pattern. Wildcards can be used to select multiple pins at once. There are three Tcl string matching schemes available with this command: the default method, the -hierarchical option, and the -compatibility_mode option. By default, pipe characters are used to separate one hierarchy level from the next. They are treated as special characters and are taken into account when string matching with wildcards is performed. When the default matching scheme is enabled, the specified pattern is matched against absolute pin names: the names that include the entire hierarchical path. All hierarchy levels in the pattern are matched level by level. Pin names of the form <absolute full cell name>\|<pin suffix> are used for matching. Note that a full cell name can contain multiple pipe characters in it to reflect the hierarchy. Any included wildcards refer to only one hierarchical level. For example, "\|" and "\|\|" produce different collections since they refer to the highest hierarchical level and second highest hierarchical level respectively. When using the -hierarchical matching scheme, pipe characters are treated as special characters and are taken into account when string matching with wildcards is performed. This matching scheme forces the search to proceed recursively through the hierarchy. The specified pattern is matched against the relative pin names: the immediate names that do not include any of the hierarchy information. Pin names of the form <relative short cell name>\|<pin suffix> are used for matching. Note that a short cell name cannot contain pipe characters. Any included wildcards are expanded to match the relative pin names. For example, "" and "\|" match exactly the same pins since the former is expanded into the latter. The -compatibility_mode matching scheme uses simple Tcl string matching on full, absolute cell names. Pipe characters are not treated as special characters when used with wildcards. The default matching scheme returns not only pins whose names match the specified filter, but also pins duplicated from these pins (refers to pins are automatically generated by Quartus from the pins). Use -no_duplicates option to not include duplicated pins. The filter for the collection is a Tcl list of wildcards, and must follow standard Tcl or Timing Analyzer-extension substitution rules. See help for the use_timing_analyzer_style_escaping command for details.
Example Usage	# Get regout pin of "reg" cell get_pins -nocase reg\|regout # Create a collection of all pins of "reg" cell get_pins reg\|* # Create a collection of all pins on the highest hierarachical level set mycollection [get_pins ] # Output pin names. foreach_in_collection pin $mycollection { puts [get_pin_info -name $pin] } # Create a collection of all pins in the design set fullcollection [get_pins -hierarchical ] # Output pin IDs and names. foreach_in_collection pin $fullcollection { puts -nonewline $pin puts -nonewline ": " puts [get_pin_info -name $pin] }
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.
