It’s coming up on a year since we published our last memory review; possibly the longest hiatus this section of the site has ever seen. To be honest, the reason we’ve refrained from posting much of anything is because things haven’t changed all that…

Testability用来表征一个manufactured design的quality. 将testability放在ASIC前端来做,成为DFT(Design For Test),用可控(controllable)可观(observable)来表征. DFT的实现的两个大方向:ad hoc和structure. 1)ad hoc:利用良好的设计习惯,来保证testability.减少无关逻辑,异步逻辑,增加可控可查点. 2)structured:更加系统,自动的方法.包括三个方法: scan…

在PD之后,netlist中会多出很多DCAP元件(去耦电容,减少IR-Drop)或者filter cell(保证芯片均匀度要求) 还有一些antenna cell也就是一些diode用来泻流,防止天线效应(生产中裸露的metal,收集电荷,击穿栅极) 版图一般由两层组成:base layer和metal layer. base layer由p-substrate和n-well组成. 封装前的芯片叫做die,长满die的晶圆叫做wafer GDS相对于RTL的要求: RTL+SDC经过synth…

计算所科研实践随笔 被淹没在论文海里的两个星期. 早上7:10分起床,草草洗漱,7:30出发,开始漫长的1小时通勤.从地铁站的安检口起,队便排的极长,让人看得头皮发麻.下到了轨道旁稍好,但每趟呼啸而来的地铁里都是满满当当,常常要等2,3趟我才能有幸站上去.我从不奢望座位.在等一趟不那么满的地铁的过程中,有时很满的地铁来了,门易开人墙难开,门快关时有些赶得急的人就踏上地铁背过身来拼命地往后压,最后强行挤出了个位置来,我在外面看得见那努力的表情. 虽说这行为不大雅观,素质上可能偏向于负面,但我脑子里…
