Overview

In this tutorial, I am going to show you how to program Xilinx X2C264A CPLD (or other CPLD) with TIAO Universal Buffered Parallel JTAG Adapter.

Required Hardware and Software

Install Xilinx Lab Tool

Download Xilinx ISE Design Suite and unzip to a temp directory, then run xsetup.exe:

Xilinx.install.labtools.1.png

Click Next:

Xilinx.install.labtools.2.png

Check agree to T&C, then click Next.

Select Lab Tools: Standalone Installation, and click Next:

Xilinx Buffered Platform Cable III Connections on TIAO Universal Buffered Parallel JTAG Adapter

Basically, make the following connections: 

* Short DB25's pin 8, 11 and 12
* Use female to female jumper wire to connect D2, D3, D4, D13 to A1, A2, A3, Y8 on TIAO Universal JTAG adapter respectively.
* Use female to female jumper wire to connect Y1, Y2, Y3, A8, GND, 3.3V to CPLD's TDI, TCK, TMS, TDO, GND and Vcc respectively.

Short DB25's PIN 8, 11 and 12

In this step, you need to solder wires to make DB25's PIN 8, 11 and 12 connected.

I soldered them together with a leg of a resistor:

Connect the female to female wires

In this example, I use XC2C64A CoolRunner-II CPLD Dev Board (RGH) as the example:

Connect the JTAG board to PC

  • Connect the JTAG board and your PC with a USB A to Mini USB cable (most digital camera supplies this kind of cable)
  • Plug the board to your PC's parallel port
  • Run Xilinx iMPACT from lab tools, select Parallel Cable III in cable setup dialog
  • Now, you can use iMPACT to read/erase/write CPLDs.
