Description

一种高效测试系统实时状态检测装置 技术领域
本申请涉及半导体测试技术领域,尤其涉及一种高效测试系统实时状态检测装置。
背景技术
目前的测试系统状态检测电路通常只能实现简单的电源与温度等简单状态监控,不能实行复杂状态检测。检测覆盖面不足将会导致测试系统带病工作,会导致系统故障或者被测器件存在误测的风险,将良品测成不良品,将不良品测成良品。如果不能及时发现故障,在测试工厂的量产测试应用时将会造成不必要的损失。
另外,现有的状态检测模式通常采用轮询采样模式进行状态检测,其过程为采集一个参数的实际状态进行比较判断,判断正常则进行下一个参数状态的采集直到检测到异常状态触发中断,状态参数或板卡较多时,总的状态采集时间会非常长。为了降低系统故障导致的误测风险,实际测试过程中尽量减少功能检测的抽检时间间隔,这必然会增加总的测试时间,严重的影响系统的测试效率,增加了测试成本。
