XJLink Manager can be used to check if the XJDemo Board is properly connected and that the license is set correctly. You can open the program from the XJ-icon on the right side of the windows taskbar. If everything is fine the XJTask Manager should look like this:
We are using version 1.2 XJDemo board (most likely version 1.2). The main functional differences are:
 
# The RAM circuit is a Holtek HT6116 2Kx8 bit as opposed to the BS62LV256SC on the v2.0 board. Refer to the schematic for the pinmapping for page 11 of the tutorial.
 
# The ADC is not available on the v1.2 board
 
# The jumper between the Altera and Xilinx device is not present on the v1.2 board
 
 
 
You can download the modified tutorial files from [http://web.ift.uib.no/~kjetil/wiki/XJTAG%20Demo%20Board.zip here].
 
 
 
The tutorial aims to give you an understanding the process of creating an XJEase test system for a circuit, and the XJEase design philosophy.
 
The tutorial can be navigated through the "Previous", "Home" and "Next" buttons at the top and bottom of each page in the tutorial.
 
The structure of the tutorial is as follows:  
 
 
 
==Circuit description==
 
The tutorial begins with a description of the XJDemo board and links to the data sheets for each of the components in the circuit.
 
 
 
==Creating the project file==
 
You will use XJDeveloper to create an XJEase description of the XJDemo board. This section explains how the various pieces of information are used, and what information can be gained from XJTAG automatically while creating the project file.
 
 
 
==Running the connection test==
 
We run a connection test and demonstrate various types of error detection using the XJDemo board.
 
 
 
==Simple device testing==
 
We create simple scripts to test the push buttons and LEDs. This illustrates the simplicity of programming in the XJEase language.
 
 
 
==More complex device testing==
 
We test the memory device, by creating a script that contains the read and write cycles for the device, along with a simple memory test that uses these functions.
 
  
==Design reuse==
+
[[Image:XJLink Manager.png]]
Using a standard memory test and some standard IIC interface code, we quickly create some tests for the BS62LV256 static RAM and the EEPROM.
 
==DFT Analysis==
 
The demo script is analysed to check the coverage of the test code and find out where extra tests need to be applied to improve the testability of the board.

XJDeveloper Tutorial

You should run the tutorial XJDeveloper tutorial (you can search for the app, or it can be found under XJTAG 3.10 in the windows start meny), the tutorial contains a detailed description on what to do. The program this tutorial is designed for is called XJDeveloper 3.10. In this tutorial you can choose between version 4.2 and 3.1 of the XJDemo board, we are using version 3.1. The tutorial provides a turtorial3.zip file with the files you're going to use. Unzip this to a new folder for your project.

Below are a pictures of versions 3.1 of the XJDemo board.

XJLink Manager

XJLink Manager can be used to check if the XJDemo Board is properly connected and that the license is set correctly. You can open the program from the XJ-icon on the right side of the windows taskbar. If everything is fine the XJTask Manager should look like this:
