XJTAG® 宣布嵌入Altium Designer®的免费DFT插件

关键特性:

  • 针对Altium Designer用户开发的新的易用DFT工具;
  • 为所有Altium Designer用户提供免费的扩展功能;
  • 从电路设计阶段及时发现错误,从而避免高成本的重新制板
  • 在硬件产品生产之前找到边界扫描链路里面的错误;
  • 充分驾驭边界扫描技术以提高可测性;

2016年2月18日英国剑桥 — 作为世界领先的边界扫描技术供应商,XJTAG®在德国纽伦伯格举办的嵌入式大会上正式发布 XJTAG DFT Assistant for Altium Designer® 工具.该工具由XJTAG开发,基于Altium Designer的免费软件扩展包,将会极大地增加这个原理图和PCB设计系统的DFT能力.

现代印刷电路板上元件的安装密度在不断增加,事实上直接访问如BGA或者LGA这类芯片的管脚是不可能的.这就给必须通过物理端子连接到一个节点或者测试点的测试设备带来了极大地挑战.边界扫描正是为解决此类问题应运而生的恰当方案,所以在设计阶段导入边界扫描链路就变得至关重要,而基于Altium Designer的XJTAG DFT Assistant共计将会通过与Altium Designer的深度整合,以帮助验证边界扫描链路的连接的正确性.

XJTAG的CEO Simon Payne介绍到,"XJTAG DFT Assistant给工程师们提供一个免费的,易于使用的扩展软件.在PCB制造生产之前,工程师就可以检查原理图设计中边界扫描链路是否正确.如果在早期侦测和改正这样的错误,公司可以节省大量的时间和金钱.当第一台原型产品正在生产的时候,用户可以利用XJTAG DFT Assistant从Altium Designer里面导出初部的XJTAG工程到XJTAG开发工具中,然后用户可以基于此开发更完善的测试项目.当产品硬件生产出来了,用户可以马上使用这些测试程序来完成生产测试.这给世界各地的电子工程师们带来一个至关重要的新能力。"

XJTAG DFT Assistant有两项关键的组件: XJTAG链路检查器(XJTAG Chain Checker)和XJTAG Access查看器(XJTAG Access Viewer);

XJTAG链路检查器可以发现如TAP的连接错误这样在JTAG扫描链路中常见的问题.一个错误的连接可以可能导致整个扫描链无法工作.XJTAG链路检查器可以发现连接错误,并且将错误报告实时呈现开发人员.与此同时,不正确的TAP终端设计也会被发现.

XJTAG Access Viewer把整个边界扫描链路在原理图上显示出来,允许用户实时的看到哪些器件在边界扫描链路中,以及在哪些地方可以提高测试覆盖率;

Altium公司的技术伙伴关系和业务发展总监Daniel Fersebner谈到,"我们非常高兴地引入XJTAG的扩展包,相信它会帮助客户在产品开发中受益.作为边界扫描技术的专家,XJTAG拥有丰富的经验来解决边界扫描链路如何在PCB上正常工作的问题.XJTAG DFT Assistant软件体现了XJTAG的经验如何在原理图设计阶段就给工程师们提供帮助,并让客户在硬件生产前就通过我们的集成设计软件受益.

边界扫描作为IEEE 1149.x系列的标准协议,被所有业界领先的半导体制造厂商所采用.边界扫描通过边界扫描链路可以访问到PCB上复杂的IC.简单的4个或5个引脚的总线可以用来依次连接JTAG兼容的器件.通过边界扫,用户可以访问到被JTAG器件所控制非JTAG的器件,以完成连接性和功能测试,与此同时还可以对非掉电存储器和FPGA/CPLD在线编程;

从原型机的开发到量产的测试,边界扫描可以检测到大范围的错误,比如短路,开路,钳制在高或者低电平,以及没有安装的上拉或者下拉电阻.XJTAG的产品也可以在不需要物理连接到Pin或者昂贵的ICT测试机,飞针或者针床的前提下,定位出错的网表.

XJTAG DFT Assistant可以通过Altium Designer扩展面板免费下载;
