IMPORTING ASSIGNMENTS

You can specify the netlist type by selecting the type from the list in the

Netlist Type column or by selecting the partition and choosing Properties

(right button pop-up menu).

If you want to make a LogicLock assignment for a partition, you can drag the

partition from the Design Partitions window directly to the LogicLock

Regions window or to a LogicLock region in the Timing Closure floorplan.

Importing Assignments

The Import Assignments command (Assignments menu) allows you to

import assignments from projects created in the Quartus II software or the

MAX+PLUS II software into a project in the Quartus II software.

The Import Assignments dialog box allows you to specify the file that

contains the assignments to import and the specific types of assignments

(Assignment Categories) to import into the QSF for the current project

revision. Click Advanced in the Import Assignments dialog box to specify

the nature of the assignments to import, specify global or instance-level

assignments to import, and specify how the assignments affect the current

design. You can use this dialog box to import settings files, CSV Files created

with the Export command (File menu), and FPGA Xchange Files (.fx), and

can create a backup of the current QSF for the design before importing

assignments. See Figure 5.
