Description

Sets or removes a location assignment.

                Valid location assignments, and settings for those
                assignments for your design are determined by the
                target device, package type, and pin count.

                To explore possible assignments and settings for your
                design and device, in the Quartus II Assignment
                Editor, specify Location for Assignment Name, and then
                click Browse in the Value column. In the Location
                dialog box, explore assignable device resources in the
                Element list, and then use the lists that appear
                (based on the element selected) to determine locations
                of resources that can be specified as the value for
                the assignment.

Assignments created or modified by using this Tcl
command are not saved to the Quartus II Settings File
(.qsf) unless you explicitly call one of the following
two Tcl commands:

1) export_assignments

                2) project_close (unless "-dont_export_assignments" is
                specified)

These two Tcl commands reside in the
::quartus::project Tcl package. You must save
assignment changes before you run Quartus(R) II
command-line executables. Note, however, that the Tcl
commands "execute_flow" and "execute_module" (part of
the ::quartus::flow Tcl package) automatically call
"export_assignments" before they run command-line
executables.
