get_all_global_assignments
Usage
get_all_global_assignments [-entity <entity_name>] -name <name> [-section_id <section
id>] [-tag <data>]
Options
-entity <entity_name>: Entity to which assignment belongs
-name <name>: Assignment name (string pattern is matched using Tcl string matching)
-section_id <section id>: Section id
-tag <data>: Option to tag data to this assignment
Description
Returns a filtered output collection of all matching global assignment values. To access each element of the
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_global_assignments" command. These
two new commands simplify the interface to retrieve information about Quartus II Settings File (.qsf)
assignments. The "get_all_global_assignments" command is still supported for backward compatibility.
The "-name" option is not case sensitive. This option can take string patterns containing special characters
from the set "*?\[]" as the value. The value is matched using Tcl string matching.
This Tcl command reads the global assignments found in the Quartus II Settings File (.qsf). This Tcl
command filters the assignment data in the .qsf and outputs the data based on the values given by the
"-name" option.
Each element of the collection is a list with the following format: { {<Section Id>} {<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:
If you tagged data by making assignments with the -tag option, then the information will be displayed in
the <Tag data> field.
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
