摘要
为满足日益增长的集成电路测试需求,研制了集成电路综合自动测试系统;该系统对外包含软件平台接口和硬件平台接口;软件平台接口主要针对在被测集成电路规模越来越庞大的背景下,测试程序开发成本高、但软件测试平台之间不能互相兼容的问题,设计了一种基于自动测试模型的集成电路测试程序开发方法,并采用典型集成电路进行了测试验证,可满足测试程序开发的需要;硬件平台接口主要满足高速信号等的传递需求,设计了基于弹性对接技术的硬件平台接口,并进行了结构尺寸、信号传递特性等指标的测试,测试数据表明,可实现测试接口板与测试头之间的稳定连接,满足最高1.6 Gbps、最大2048通道数字信号等的传递需求。
In order to meet the increasing demand of integrated circuit(IC)tests,an integrated circuit automatic test system is developed.The system includes software platform interface and hardware platform interface.The software platform interface for IC is tested under the background of more and more large-scale IC,there are the questions of high cost for the test program development and incompatible with the software test platform,a model-based automatic IC test program development method is proposed,and the typical integrated circuit is used to test and verify,basically meet the need of the test program development.The hardware platform interface mainly meet the demand of the high-speed signal such as transfer,the hardware platform interface based on flexible docking technology is designed,and the indexes of the system structure size and signal transmission characteristics are carried out to test,the test data show that it can realize the connected stability between test interface board and plug,and satisfy the transmission requirements of the digital signal with the highest transmission speed of 1.6 Gbps and maximum of 2048 channels.
