This page contains links to the data sheets and reference manuals for the parts and software we will be using. Please don't print them out; this will waste paper.

We will be using the Digilent Pegasus Board which uses a Xilinx Spartan II FPGA.

• Pegasus Board Reference Manual
• Pegasus Board Schematic

We will be using the Xilinx ISE WebPack 8.2i(free) and ModelSim XE III 6.1e (Starter Edition). The most current version is ISE WebPack 9.1i, so make sure you download 8.2i rather 9.1i!!!

You can download this software(free) from the Xilinx ISE Webpack page. Click on ISE Classics in the menu on the left. Then click on Download Free in the menu on the right. You will then need to

1. Register for a Xilinx account (painless).
2. Fill out the survey.
3. Download ISE 8.2i (use WebInstall) including Service pack 3.
4. Download ModelSim Xilinx Edition-III (MXE-III)

These are industrial strength tools. We will guide you through their use, keeping things simple. You are welcome to explore other features of the tools, but make sure to save your work first.

Instructions for:

• Downloading a bit stream to the Pegasus board.
• Creating a new project.
• Entering a schematic.
• Creating a schematic symbol.
• Simulating your design with ModelSim.
• Using buses in a schematic.
• Using Verilog to describe Combinational Logic.
• Archiving and storing your ISE project.

• Resistor color code
