2.6.5. The get_names Command

To query a filtered output collection of all matching node name IDs found in a compiled Quartus® Prime project, use the get_names command.

To access each element of the output collection, use the Tcl command foreach_in_collection . For get_names or foreach_in_collection command example, type get_names -long_help or foreach_in_collection -long_help.

If the -node_type option is not specified, the default value is all.
If the -observable_type option is not specified, the default value is all.
The node type pin includes input, output, bidir, assigned, unassigned, virtual, and pin.
The node type qsf include names from the .qsf settings file.
The node type all includes all node types.
The node type all_reg includes all node types and registers post-fitting.

The value for -observable_type option can be one of the following:

Table 9. Values for `observable_type` Option
Observable Type	Description
`all`	Use post-Fitter information. If it is not available, post-synthesis information is used. Else, pre-synthesis information is used if it exists.
`pre_synthesis`	Use pre-synthesis information.
`post_synthesis`	Use post-synthesis information.
`post_fitter`	Use post-Fitter information.
`post_asm`	Use post-Assembler information. The post-Assembler information is supported only for designs using the HardCopy II device family.
`stp_pre_synthesis`	Use Signal Tap pre-synthesis information.

Arguments

Following table lists the get_names command arguments:

Table 10. The `get_names` Command Arguments
Argument	Description
`-h \| -help`	Displays a short help.
`-long help`	Displays a long help with examples and possible return values.
`-entity<wildcard>`	Specifies the entity to get names from hierarchies instantiated by the entity.
`-filter<wildcard>`	Specifies the node's full path name and wildcard characters.
`-node_type <all\|comb\|reg\|pin\|input\|output\|bidir\|hierarchy\|mem\|bus\|qsf\|state_machine\|assigned\|unassigned\|all_reg\|partition\|virtual>`	Filters based on the specified node type.
`-observable_type <all\|pre_synthesis\|post_synthesis\|post_fitter\|stp_pre_synthesis>]`	Filters based on the specified observable type.

Return Values

Following table lists values returned by the get_names command:

Table 11. The `get_names` Command Return Values
Code Name	Code	String Returned
`TCL_OK`	0	INFO: operation successful
`TCL_ERROR`	1	ERROR: Can't find active revision name. Make sure there is an open, active revision name.
`TCL_ERROR`	1	ERROR: Get names cannot return <string> because the name was found in a partition that's not the root partition. Refine your get_names search pattern to exclude child partitions.
`TCL_ERROR`	1	ERROR: Compiler database does not exist for revision name: <string>. At the minimum, run Analysis & Synthesis with the specified revision name before using this Tcl command.
`TCL_ERROR`	1	ERROR: Illegal node type: <string>. Specify "all", "comb", "reg", "pin", "hierarchy", or "bus".
`TCL_ERROR`	1	ERROR: Illegal observable type: <string>. Specify "all", "pre_synthesis", "post_synthesis", or "post_fitter".
`TCL_ERROR`	1	ERROR: You must open a project before you can use this command.

Example Use

# Search for a single post-Fitter pin with the name accel and make assignments
set accel_name_id [get_names -filter accel -node_type pin -observable_type post_fitter]

foreach_in_collection name_id $accel_name_id {
   # Get the full path name of the node
   set target [get_name_info -info full_path $name_id]
   # Set multicycle assignment
   set_multicycle_assignment -to $target 2
   # Set location assignment
   set_location_assignment -to $target Pin_E22
  }
# Search for nodes of any post-Fitter node type with name length <= 5. The default node type is "all"
set name_ids [get_names -filter ????? -observable_type post_fitter]
foreach_in_collection name_id $name_ids {
   # Print the name id
   puts $name_id
   # Print the node type
   puts [get_name_info -info node_type $name_id]
   # Print the full path (which excludes the current focus entity from the path)
   puts [get_name_info -info full_path $name_id]
  }
# Search for nodes of any post-Fitter node type that end in "eed".
# The default node type is "all"
  set name_ids [get_names -filter *eed -observable_type post_fitter]
  foreach_in_collection name_id $name_ids {
   # Print the name id
   puts $name_id
   # Print the node type
   puts [get_name_info -info node_type $name_id]
   # Print the full path (which excludes the current
   # focus entity from the path)
   puts [get_name_info -info full_path $name_id]
  }
