## Converting Design Architect Schematics into MAX+PLUS II-Compatible EDIF Netlist Files with the ENWrite Utility

After you have created a Design Architect schematic or a hierarchical schematic design that uses multiple design entry methods, you can use the Mentor Graphics ENWrite utility to convert it into an EDIF netlist file that can be processed with the MAX+PLUS® II software.

To generate an EDIF netlist file for use with the MAX+PLUS II Compiler, go through the following steps:

1. Create a Design Architect Schematic that follows the guidelines described in Creating Design Architect Schematics for Use with MAX+PLUS II Software.

2. Select the folder for your project, press Button 3, and choose Open max2_enw from the Navigator window to open Design Viewpoint Editor (DVE), then ENWrite. You can also start the ENWrite utility by typing `max2_enw` at the UNIX prompt.

3. Choose OK in the $invoke_enw dialog box to accept the default names for the DVE viewpoint altera_edif, which is used internally by ENWrite, and the ENWrite hierarchical EDIF netlist file <design name>.edf. Specify OFF for the port array construct in the EDIF netlist file.

| The MAX+PLUS II software supports bus constructs in EDIF 2 0 0 and 3 0 0 netlist files, which allow you to retain any bus structures in your design. To preserve a bus in the EDIF netlist file, turn on the port array construct option in the $invoke_enw dialog box. However, if your design contains library of parameterized modules (LPM) functions, you should not use this feature because LPM 2.0.1 and 2.1.0 functions do not support EDIF bus constructs.

After DVE checks the Design Architect schematic, ENWrite generates <design name>.edf and automatically copies it to your project's directory.

4. Compile the resulting EDIF netlist file with the MAX+PLUS II Compiler, as described in Compiling Projects with MAX+PLUS II Software.
