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: { {

} {}
{} {} {} }

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
