To use the Quartus^® II software with Cadence NC-VHDL software, you must first install the Quartus II software, then establish an environment that facilitates entering and processing designs. The Quartus II/NC-VHDL interface is installed automatically when you install the Quartus II software on your computer. Refer to the Quartus II Installation & Licensing for PCs or the Installation & Licensing for UNIX and Linux Workstations manuals for more information on installing the software and the directories that are created during the Quartus II installation. One of the directories created during the Quartus II installation is /quartus/eda/sim_lib, which contains the VHDL functional simulation libraries and timing simulation libraries for Quartus II primitives.

1. Make sure you have installed the following versions of the Quartus II software and the NC-VHDL software:

Cadence	Altera®
NC-VHDL version 3.3	Quartus II version 2.2

This version of the NC-VHDL software supports all Altera devices supported by the Quartus II software.

The Quartus II Software Release Notes are available on the Altera web site and provide up-to-date information on which versions of Cadence software 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. To set up your working environment for the Quartus II/NC-VHDL software interface:

(For UNIX workstations only) The information presented here assumes that you are using the C shell and that your Quartus II system directory is /usr/quartus. If not, you must use the appropriate syntax and procedures to set environment variables for your shell.

1. (For UNIX workstations only) Add the following environment variables to your .cshrc file:

   setenv QUARTUS_ROOTDIR /usr/quartus
   

   setenv CDS_INST_DIR <NC-VHDL installation directory path>

2. Add the $CDS_INST_DIR/tools/bin directories to the PATH environment variable in your .cshrc file. Make sure these paths are placed before the Cadence hierarchy path.

3. Add /usr/dt/lib and /usr/ucb/lib to the LD_LIBRARY_PATH environment variable in your .cshrc file.

4. Source your .cshrc file by typing source .cshrc at the command prompt.

3. If you are performing a functional simulation, to continue with the NC-VHDL simulation flow, proceed to one of the following steps:

   • 2. Perform a Functional Simulation with the NC-VHDL Software
   • 2. Perform a Functional Simulation with the NC-VHDL Software (Command-Line)

4. If you are performing a timing simulation, to continue with the NC-VHDL simulation flow, proceed to one of the following steps:

   • 3. Perform a Timing Simulation with the NC-VHDL Software
   • 3. Perform a Timing Simulation with the NC-VHDL Software (Command-Line)
