XJEase and XJDeveloper Tutorial

You should run the tutorial at Program Files> XJTAG 2.3 > Help > XJEase and XJDeveloper Tutorial This tutorial assumes you have a version 2.0 of the XJDemo board. Below are pictures of versions 1.2 and 2.0 of the XJDemo board side-by-side so you can identify which you have. The main identifying feature of version 2.0 is its blue thumbwheel.

Running the XJDemo version 2.0 demo on the XJDemo version 1.2 card

We are using version 1.2 XJDemo board (most likely version 1.2). The main functional differences are:

  1. The RAM circuit is a Holtek HT6116 2Kx8 bit as opposed to the

, then please use the tutorial file on your installation CD in the "XJDemo 1.2" directory or contact XJTAG Support (support@xjtag.com).

Overview

This tutorial aims to give you an understanding the process of creating an XJEase test system for a circuit, and the XJEase design philosophy. 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

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.

The tutorial can be navigated through the "Previous", "Home" and "Next" buttons at the top and bottom of each page in the tutorial.
