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 the 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.

ViewDraw Schematics

In ViewDraw 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 (.edf) into the ACF format. For information on making MAX+PLUS II-compatible resource assignments, go to the following topics:

Installing the Altera-provided MAX+PLUS II/Viewlogic interface on your computer automatically creates the following sample ViewDraw schematic file, which includes resource assignments:

NOTE: Go to Viewlogic documentation for information on how to assign properties. Go to "Resource Assignments in EDIF Input Files" and "Assigning Resources in a Third-Party Design Editor" in MAX+PLUS II Help for more information on assignments or properties that can be assigned in ViewDraw.

VHDL Design Files

For VHDL-based designs, you must use the MAX+PLUS II software or the setacf utility to enter resource assignments. For information on using the setacf utility, go to Modifying the Assignment & Configuration File with the setacf Utility.

Go to:

For information on entering assignments in the MAX+PLUS II software with Assign menu commands or in an ACF, go to "resource assignments" or "ACF, format" in MAX+PLUS II Help using Search for Help on (Help menu).
