介绍一种采用后驱动技术的故障注入方法 ,可以在不拆卸被测系统任何部件也不需在被测系统中添加任何测试接口的情况下 ,对被测系统实施方便灵活的故障注入。文章首先简单介绍了智能化BIT测试适配器 ,接着重点阐述了后驱动技术的原理、后驱动故障注入的实现及后驱动故障注入的特点。
A fault injection method using post-drive technology is introduced to implement a convenient and flexible fault injection into the system under test without disassembling any part of the system under test or adding any test interface to the system under test. The article first briefly introduces the intelligent BIT test adapter, and then focuses on the principle of post-drive technology, the realization of post-drive fault injection and the characteristics of post-drive fault injection.
