• How to create EDO and FIT files.
• When is the .FIT file necessary
• Known issues using Altera MAX PLUS II

The .EDO file is a flattened edif netlist. The .FIT file, if required, defines the external pins.

1. From MAX+Plus II File menu, select PROJECT --> NAME to load your source project.
   
2. From MAX+Plus II Main menu, select COMPILER.
   
3. From MAX+Plus II Interfaces menu, select EDIF NETLIST WRITER (selection is indicated with a checkmark).
   
4. From Interfaces menu, select EDIF NETLIST WRITER SETTINGS.
   Select EDIF version 3 0 0. Under CUSTOMIZE, select "Map Illegal EDIF Characters".
   Under CUSTOMIZE, select "Include Special Primitives" if logic primitives FILTER or RISEFALL are used.
5. From the Compiler window, click START to compile.

   The resultant .EDO file will be ready to run with FS-ATG.
   

When is the .FIT file necessary

The .FIT file is only required when the edif netlist contains <member-array> arguments AND the edif netlist was generated using version 2 0 0 of the IEEE standard. Please note that Altera MAX PLUS II defaults to edif version 2 0 0, so you have to explicitly specify the EDIF 3 0 0 format when you compile your design.
