Converting ViewDraw Schematics or VHDL Designs into MAX+PLUS II-Compatible EDIF Netlist Files with the edifneto Utility
You can use the edifneto utility to generate an EDIF netlist file from a ViewDraw schematic or VHDL Design File (.vhd). This file can be imported into the MAX+PLUS® II software as an EDIF Input File with the extension .edf. To generate an EDIF netlist file, follow these steps:
- Be sure to set up your working environment correctly, as described in Setting Up the MAX+PLUS II/Viewlogic Powerview Working Environment.
- Create a ViewDraw schematic and save it in your working directory, as described in Creating ViewDraw Schematics for Use with MAX+PLUS II Software.
or:
Create a VHDL Design File, analyze it, and synthesize and optimize it, as described in the following topics:
- Start the edifneto utility by double-clicking Button 1 on the max2_edifo icon in the Design Tools Drawer or the Max2 Express Drawer in the Altera Toolbox. You can also start the edifneto utility by typing
edifneto at the UNIX prompt.
- If you are converting a ViewDraw schematic, specify the <design name> for the Wire File Name option in the edifneto dialog box. If you are not using the Altera® toolbox, do not specify Altera for the Level option in the edifneto dialog box.
- If you are converting a VHDL Design File, or if your ViewDraw schematic instantiates Library of Parameterized Modules (LPM) functions, specify Altera and VHDL as the Level in the edifneto dialog box.
- Choose OK to generate the EDIF netlist file. The edifneto utility creates the max2 subdirectory under your working directory. The max2 subdirectory contains the EDIF netlist file for your design.

When the edifneto utility generates an EDIF netlist file from a design that instantiates LPM functions, the EDIF netlist file may contain parameters with incorrect parameter names. To correct this problem, go to the /usr/maxplus2/viewlogic/bin directory and type chlpmpty <design name>.edf at the UNIX prompt to run the Altera-provided chlpmpty script, which converts all of the parameters to their correct names. |
- Process the <design name>.edf with the MAX+PLUS II Compiler, as described in Compiling Projects with MAX+PLUS II Software.
