Allows you to define a custom group of nodes to which you can make assignments. The members of a defined assignment group can include regular node names, wildcards, and/or names of other assignment groups. You can also explicitly exclude specific nodes, wildcards, and/or assignment groups from an assignment group.
To create assignment groups, on the Assignments menu clickAssignment Groups.In theAssignment Groupsdialog box, name the group and specify members and exceptions. Use the Assignment Editor to create assignments to the group.
Alternatively, you can create assignment groups in a Tcl script or shell with the assignment_group command using the following command:
assignment_group "<group name>" -add_member <node name/wildcard/assignment group name>
The assignment_group command is contained in the ::quartus::project Tcl pacakge.
