在scan stitch之后,scan synthesis就已经完成, Scan extraction主要用来从scan design中extracing所有的instance,来保证scan chain的完整性. 并保证所有的design change都整合到scan design. Scan Verificaiton 1)在shift operate中的hold time violation,如果两个scan cell是同时钟,需要由CTS来保证clock skew有一个 minimum的值…

一个典型的scan实现的flow: clock mux和一些rst,在Scan中都被bypass掉,是不能测到的.所以DFT的test coverage一般就在97%或98%. scan design rule checking and repair: 可以在presynthesis RTL design或者postsynthesis gate-level design上进行, 经过scan repair之后的design,称为testable design. scan synthsis是将一个…

fault simulation是指对fault circuit的simulation,来locate manufacturing defects并且进行fault diagnosis. logic simulation针对logic circuit model的simulation,主要有compiled-code和event-driven两种techniques. Logic simulation针对design verification的: 一般design verificaiton起始于…

前言 对于一个程序猿来讲怎样来最直接的来衡量他的技术能力和产出呢?我想最直观的作法是看他的代码编写能力,就拿我常常接触的一些程序猿来看,他们买了非常多技术重构类书籍.可是看完后代码编写能力并没有显著提高.有人说可以用代码review工具啊,可是像市面上的这些代码review工具.仅仅能帮助我们解决表面的bug和规范点.还无法帮助我们发现更深层次的设计问题. 以下我将结合<软件设计重构>这本书谈谈在进行代码review的时候.须要关注的哪些点. 一.技术债务 何为技术债务? 技术债务是有意或无意…
