Xilinx ISE quick-start guide

You can download the free ISE here.

1. Create a new project

2. Select the project directory

Click "Next".

3. Select the device

For example, for a Dragon 50K, choose the Spartan-2 XC2S50 device in TQ144 package.

Click "Next".

4. Select the top-level file

Click "Next" until "Finish".

5. Write the top-level file

ISE shows you the empty module template:

Type the following text (as-is, this is case sensitive):

and save.

6. Assign the pins

With the "ledblink.v" file selected in the Project browser, double-click on "Floorplan IO - Pre-Synthesis". ISE analyses your design, and after a few seconds, it asks you if you want to create a "UCF" file. Say "Yes".

A new software ("Xilinx PACE") opens. Set the pin assignment (for example, with a Dragon board, assign P18 to clk and P51 to LED).

Save the UCF and close PACE.

7. Compile the design

With the "ledblink.v" file selected in the Project browser, double-click on "Generate Programming File"

The design compiles, and after a minute, the design is ready to be downloaded into the FPGA.
