Entering Resource Assignments
The MAX+PLUS® II software allows you to enter a variety of resource and device assignments for your projects. Resource assignments are used to assign logic functions to a particular pin, logic cell, I/O cell, embedded cell, row, column, Logic Array Block (LAB), Embedded Array Block (EAB), chip, clique, local routing, logic option, timing requirement, or connected pin group. In MAX+PLUS II software, you can enter all types of resource and device assignments with Assign menu commands. You can also enter pin, logic cell, I/O cell, embedded cell, LAB, EAB, row, and column assignments in the MAX+PLUS II Floorplan Editor. The Assign menu commands and the Floorplan Editor all save assignment information in the ASCII Assignment & Configuration File (.acf) for the project. In addition, you can edit ACFs manually in any standard text editor or with the setacf utility.
Design Architect Schematics
In Design Architect schematics, you can assign a limited subset of these resource assignments by assigning properties to symbols. These properties are incorporated into the EDIF netlist file(s). The MAX+PLUS II software automatically converts assignment information from the EDIF Input File into the ACF format. For information on making MAX+PLUS II-compatible resource assignments, go to the following topics:
Installing the Alteraprovided MAX+PLUS II/Mentor Graphics/Exemplar Logic interface on your computer automatically creates the sample Design Architect schematic file /usr/maxplus2/examples/mentor/example4/fa2, which includes resource assignments.
VHDL & Verilog HDL Design Files
For Verilog HDL- and VHDL-based designs, you must use the MAX+PLUS II software or the setacf utility to enter resource assignments. Go to Modifying the Assignment & Configuration File with the setacf Utility for more information.
