About a dozen years ago, the world of test had reached an economic impasse: most digital designs had become sufficiently complex that standard scan testing techniques were no longer cost-effective.

把可扫描的寄存器连成扫描链 如下图所示：左边是普通寄存器，右边是可扫描寄存器，D端前面加一个二选一的MUX，选择端是scan_enable，为1时选择SI端，为0时选择D端。 如下图所示：把所有可扫描寄存器首尾连接在一起，就构成了扫描链。注意，增加了三个端口 ...

We've compiled a list of some of the best OBD2 diagnostic scanners describing their features, specifications, compatibility, and benefits. The automotive industry has a huge variety of OBD2 scanners ...

The Joint Test Action Group (JTAG) formed in Europe in the late 1980s. Up until that time, most printed circuit boards (PCBs) were populated with chips that had exposed pins that were soldered through ...

Whether in a test vehicle or in a backpack, the lightweight, compact R&S TSME drive test scanner from Rohde & Schwarz is setting new standards when it comes to optimizing wireless communications ...

一次酒局，听业内某位DFT 大拿讲DFT 技术革新：先是感慨近几年工艺跟设计踏着一个又一个技术热点或噱头『突飞猛进』，以致整个数字实现链路上的相关技术大都发生了巨变，尤其是在AI 加持下，但DFT 作为数字实现链路上非常重要的一环却似乎一直都『止步不 ...

For decades, process and design scaling has triggered the adoption of transformative test solutions. About twenty years ago, when at-speed test became a de-facto ...

Yield improvement at sub 100-nm technologies relies on the latest scan test techniques. As IC feature sizes shrink below 90 nm, in-line inspection techniques to determine yield-limiting problems ...

At Alcatel-Lucent, we test chassis-level products that provide 42 board slots on a midplane, essentially a passive backplane that accepts boards on its front and rear sides. Thirty-four of those slots ...
