Xilinx 6.3 Tutorial

•This example will create a 4-bit counter module using a top-level schematic as a block editor.

•This design contains HDL (Hardware Description Language) counter modules created with examples from the templates.

•1) Create a new project and counter module

•2) Modify the counter module (ISE tutorial in Documentation)

•2B) Modify the AND Module

Xilinx 6.3 Integrated Software Environment (ISE)1) Start Programs Xilinx ISE 6.x Project Navigator

2) Select File New Project

1) First Screen

3) Enter Tutorial in the Project Name field, the location will be automatically entered

4) Select Schematic from the Top Level Dropdown

5) ( hit Next )

17) Select finish in the summary dialog box

ISE creates and displays the new project and opens the counter.vhd file in the editor

Xilinx 6.3 Tutorial (Part 2)

Insert the port declarations, and the behavioral code for the VHDL counter from the ISE language templates

1) Open the language templates by selecting Edit Language templates

(or selecting the shortcut light bulb )

Creating a test Bench Waveform Source1) Select the counter.vhd in the sources project window

2) Select Project new source


3) In the new source dialog box select Test Bench Waveform

4) Type in the name counter_tbw

5) Select Next

6) Click Next (you could associate you test bench with other sources)


7) Click Finish


AND Gate

Output Waveform for AND Gate


Output Waveform of circuit Counter.
