4.1.28.9. get_all_instance_assignments (::quartus::project)

The following table displays information for the get_all_instance_assignments Tcl command:

Tcl Package and Version	Belongs to ::quartus::project
Syntax	`get_all_instance_assignments [-h \| -help] [-long_help]` `[-entity` <entity_name> `]` `[-fall]` `[-from` <source> `]` `-name` <name> `[-rise]` `[-section_id` <section id> `]` `[-tag` <data> `]` `[-to` <destination> `]`
Arguments	`-h \| -help`		Short help
	`-long_help`		Long help with examples and possible return values
	`-entity` <entity_name>		Entity to which assignment belongs
	`-fall`		Option applies to falling edge
	`-from` <source>		Source of assignment (string pattern is matched using Tcl string matching)
	`-name` <name>		Assignment name (string pattern is matched using Tcl string matching)
	`-rise`		Option applies to rising edge
	`-section_id` <section id>		Section id
	`-tag` <data>		Option to tag data to this assignment
	`-to` <destination>		Destination of assignment (string pattern is matched using Tcl string matching)
Description	Returns a filtered output collection of all matching instance assignment values. To access each element of this output collection, use the Tcl command "foreach_in_collection". To see example usage, type "foreach_in_collection -long_help". In version 5.0 of the ::quartus::project package, two new Tcl commands "get_all_assignments" and "get_assignment_info" have been introduced to replace the "get_all_instance_assignments" command. These two new commands simplify the interface to retrieve information about Quartus Prime Settings File (.qsf) assignments. The "get_all_instance_assignments" command is still supported for backward compatibility. The "-name" option is not case sensitive. The "-to" and "-from" options are case sensitive. These options can take string patterns containing special characters from the set "?\[]" as values. The values are matched using Tcl string matching. Note that bus names are automatically detected and do not need to be escaped. Bus names have the following format: <bus name>[<bus index>] or <bus name>[] The <bus name> portion is a string of alphanumeric characters. The <bus index> portion is an integer greater than or equal to zero or it can be the character "" used for string matching. Notice that the <bus index> is enclosed by the square brackets "[" and "]". For example, "a[0]" and "a[]" are supported bus names and can be used as follows: # To match index 0 of bus "a", type: get_all_instance_assignments -name LOCATION -to a[0] # To match all indices of bus "a", type: get_all_instance_assignments -name LOCATION -to a[*] All other uses of square brackets must be escaped if you do not intend to use them as string patterns. For example, to match indices 0, 1, and 2 of the bus "a", type: get_all_instance_assignments -name LOCATION -to "a[escape_brackets \[]\[0-2\][escape_brackets \]]" For more information about escaping square brackets, type "escape_brackets -h". This Tcl command reads in the instance assignments found in the Quartus Prime Settings File (.qsf). The command filters the assignments data found in the .qsf and outputs the data based on the values specified by the "-name", "-from", and "-to" options. Each element of the collection is a list with the following format: { {<Section Id>} {<Source>} {<Destination>} {<Assignment name>} {<Assignment value>} {<Entity name>} {<Tag data>} } Certain sections in the .qsf can appear more than once. For example, because there may be more than one clock used in a project, there may be more than one CLOCK section each containing its own set of clock assignments. To uniquely identify sections of this type, a <Section Id> is used. <Section Id> can be one of three types. It can be the same as the revision name, or it can be some unique name. The following is a list of sections requiring a <Section Id> and the associated <Section Id> description: Section Id Description --------------------------- ------------------------------ CHIP Same as revision name LOGICLOCK_REGION A unique name EDA_TOOL_SETTINGS A unique name CLIQUE A unique name BREAKPOINT A unique name CLOCK A unique name AUTO_INSERT_SLD_NODE_ENTITY A unique name If you tagged data by making assignments with the -tag option, then the information will be displayed in the <Tag data> field. For entity-specific assignments, use the "-entity" option to retrieve the assignment(s) from the specified entity. If the "-entity" option is not specified, the value for the FOCUS_ENTITY_NAME assignment is used. If the FOCUS_ENTITY_NAME value is not found, the revision name is used.
Example Usage	## Print out all the timing requirements ## using the foreach_in_collection method. ## Use wildcards to catch TSU_REQUIREMENT, TCO_REQUIREMENT, ## and others. set asgn_col [get_all_instance_assignments -name _REQUIREMENT] foreach_in_collection asgn $asgn_col { ## Each element in the collection has the following ## format: { {} {<Source>} {<Destination>} {<Assignment name>} {<Assignment value>} {<Entity name>} {<Tag data>} } set from [lindex $asgn 1] set to [lindex $asgn 2] set name [lindex $asgn 3] set value [lindex $asgn 4] set entity [lindex $asgn 5] set tag [lindex $asgn 6] puts "$entity: $name ($from -> $to) = $value" } ## Get all the location assignments with ## the destination bus name "timeo". set bus_name "timeo" set location_asgns [get_all_instance_assignments -name LOCATION -to $bus_name[]]
Return Value	Code Name	Code	String Return
	TCL_OK	0	INFO: Operation successful
	TCL_ERROR	1	ERROR: Assignment is not an instance assignment: <string> -- it is a global assignment. Specify an instance assignment name or use the global assignment commands.
	TCL_ERROR	1	ERROR: Can't find file(s) associated with assignment. Specify a different assignment name.
	TCL_ERROR	1	ERROR: Can't find section information for assignment. Specify a different assignment name.
	TCL_ERROR	1	ERROR: Can't find active revision name. Make sure there is an open, active revision name.
	TCL_ERROR	1	ERROR: Entity does not exist or uses illegal name characters: <string>. Specify a legal entity name.
	TCL_ERROR	1	ERROR: Can't run Tcl command while a process is in progress: <string>. To run the command, stop the compilation or simulation; or wait for the compilation or simulation to complete.
	TCL_ERROR	1	ERROR: Value <string> for the -<string> option is illegal. Specify a legal value.
	TCL_ERROR	1	ERROR: Options cannot be specified together: -<string>, -<string> and -<string>. Specify only one or two of the three options.
	TCL_ERROR	1	ERROR: Missing destination for assignment. Specify the destination for the assignment.
	TCL_ERROR	1	ERROR: You must open a project before you can use this command.
