现在的工业量产的高速芯片都会要求能做DC SCAN测试和AC SCAN测试,所以DFT工程师也要同时插入两种测试电路,产生两套测试patterns。 具体实现流程如下 1 读入没有插入scan的网表 2 使用Design compiler 插入scan chain和OCC (on chipclocking)模块,同时插入mux, fix DRC 3 使用Testcompress 实现EDT压缩scan chain 4 ...
但是1995年以后，测试科学家和工程师发现通过DC SCAN测试没有缺陷的芯片在高工作频率下使用会有问题。其根本原因是随着制造工艺向深亚微米迈进，芯片的工作频率也提高到200M-1G，原来的SCAN测试方法和模型不再能捕捉到所有的std-logic的制造缺陷。大家的一致想法就是-奔跑吧，SCAN ，把SCAN的频率增加到与芯片的真实...

It is measured that the power consumption of one stage for the proposed scan driver with AC–DC type output module at the clock frequency of 16.7kHz is 170μW, as well as 393μW for the proposed scan driver with the conventional AC–AC type output module. It is shown from the ...

空口扫描模板:wlan-air-scan 如果AP组和单个AP下都有配置,则单个AP下的配置优先生效。 对于新创建的模板,用户配置完成后,需要将此模板引用到AP或者AP组,才能最终生效。 在AC上配置空口扫描功能 # 进入空口扫描模板“wlan-air-scan”,配置空口扫描信道集合。默认情况下,空口扫描信道集合是当前国家码支持的所有信道。
