1. Set Up the Synplify Working Environment

To use the Quartus® II software with the Synplicity Synplify software, you must first install the Quartus II software, then establish an environment that facilitates entering and processing designs. To set up the Synplify working environment:

  1. Make sure you have installed the correct versions of the Quartus II software and the Synplify software:

    2. Synplicity
    Altera®
    Synplify version 7.2
    VHDL & Verilog Synthesis for FPGAs and CPLDs
    Quartus II
    version 2.2

    This version of the Synplify software supports all Altera devices supported by the Quartus II software.

    Note: The Quartus II Software Release Notes are available on the Altera web site and provide up-to-date information on which versions of Synplify applications are supported by the current version of the Quartus II software. The Quartus II readme.txt file provides information on installation and operating requirements. You should read the Release Notes and readme.txt file before installing the Quartus II software. After installation, you can open the Release Notes and readme.txt file from the Quartus II Help menu.

  2. Make sure the appropriate Quartus II/Synplicity interface subdirectories have been created in the Quartus II system directory (by default, the /usr/quartus directory on UNIX workstations and the \quartus directory on PCs) during Quartus II installation. For information on the other directories that are created during Quartus II installation see "Quartus II File Organization" in the Quartus II Installment & Licensing for PCs and the Quartus II Installation & Licensing for UNIX and Linux workstations manuals.

    3. Quartus II Directory Organization
    Directory
    Description
    ./lmf Contains the Altera-provided Library Mapping File, synplcty.lmf, which maps Synplicity logic functions to equivalent Quartus II logic functions.

    You do not need to set any initialization or project variables before using Synplicity software with the Quartus II software. Synplicity software features Direct Synthesis Technology that performs technology mapping directly to Altera device logic cells by inserting architecture-specific primitives to implement features such as logic cells, parallel expanders, carry chains, and cascade chains. However, you must specify the environment variable for use with the Quartus II and Synplify software:

  3. To specify the environment variable for the Quartus II software:

    4. For Windows NT and Windows 2000:

    1. Choose Settings (Windows Start menu), and then choose Control Panel (Settings menu).

    2. Double-click the System icon in the Control Panel window.

    3. In the System Properties dialog box, click the Environment tab.

    4. In the Variable box, type QUARTUS_ROOTDIR.

    5. In the Value box, type <disk drive>:<Quartus II installation directory>.

    6. Click OK.

    For Windows 98:

    1. With a text editor, open the PC's autoexec.bat file.

    2. Type the following environment variable on a separate line in the autoexec.bat file:

      3. set QUARTUS_ROOTDIR=<disk drive>:<Quartus II installation directory>

    3. Click OK.

    4. Save the autoexec.bat file.

    5. Restart the PC.

    For UNIX workstations:

    1. Update the QUARTUS_ROOTDIR variable that is specified in the .cshrc file by typing the following command at the command prompt:

      setenv QUARTUS_ROOTDIR=<disk drive>:<Quartus II installation directory> 

    2. After saving the changes to the .cshrc file, type the following commands at the command prompt:

      # cd
      # source .cshrc

  4. To continue with the Synplify design flow, proceed to 2. Create a Design for Use with the Synplify Software.
