智能芯片测试系统的开发与设计 摘要 随着计算机技术和微电子技术的迅速发展，智能芯片测试系统的应用越来越广泛。测试过程应用于智能芯片的制造过程，其主要目的都是为NI公司的数据采集卡（NI-DAQ）PCI-6221LabVIEW编程语言对该测试系统的控制部分以及结果比对部分进行了设计，最终实现了一个闭环的测试系统的设计并给出测试结果，主要用D/A芯片来实现设计。 与传统的测试方法相比，设计更开放与灵活，便于修改，成功的实现了数字端口的控制，模拟量的采集以及结果的比对与显示。 关键字：虚拟仪器，LabVIEW，数据采集 Abstract With the rapid development of the computer technology and microelectronics technology,Smart chip-testing systems are used more widely. The testing process are used in smart chip process, Main purpose is to provide a measure for smart chip quality and reliability. The article introduces the important role of the smart microchip testing and analyzes the chip test system development and situation. It also puts forward the corresponding design scheme. The system uses data acquisition card to collect the measuring parameters and chooseAmerica NI company’s data collection card (DAQ)M series NI-models :PCI6221 for acquisition signal equipment, applies the LabVIEW programming software for the test system software parts, the control parts and the result.The LabVIEW realizes the design of closed loop testing system and gives out the results, Mainly use D/A chip to implement the design. Compared with the traditional test methods, it is more open and flexible, easy to modify. It makes the design of digital control ports, analog capture and compare and display the results succeed.
