Physical design:物理设计,决定单元(或者其他电路元件)和它们的连接在集成电路版图中几何布置的过程 Physical verification:物理验证,检查版图设计的正确性,包括下述的版图验证: 遵守所有的技术需求——设计规则检验; 是否和原始网表一致——版图和原理图一致性检验; 没有天线效应——天线规则检验; 遵守所有的电器需求...

数字电路实现中的DRC 数字实现硅农大方向可分为前端后端或中端后端,再细分可分为综合、DFT、形式验证、PR, PV, PI, STA 等,细分之后各工种缝扣子的缝扣子,挂衣领的挂衣领,相互有了差别,但是不论哪一个工种,都会涉及到一个词叫DRC: Design Rule Check. 数字电路实现中的DRC 老驴只知道以下三类: Timing 相关...
全称design rule check。设计规则检查。这是后端布局布线完成后signoff的一个重要指标。 版图完成后需要做物理验证(physical verification),首先是对版图进行设计规则检查,晶圆代工厂对各自不同工艺参数制定出满足芯片制造良率的同一工艺层及不同工艺层之间几何尺寸的最小值,这些最小值规划的集合就是版图设计规则。 DRC...
1. Work closely with process RD team to develop DRC/LVS for design readiness. 2. Provide customer support to world-wide leading design house. 3. Initial more innovation to continue optimize development efficiency. 4. Work closely with various departments (Physical design/integration/Device RD/Produ...

Some post-tapeout tools support "progress_meter on" in Litho File. The Calibre FullScale platform also puts out progress estimates. I am guessing you probably aren't using those, though, as most Calibre users are on the design side. Best- Sam. LikeLikedUnlikeReply...
Yield and timing goals require dramatic increases in design rulecomplexity. Lithographic, electrical, chemical and mechanical effects are increasingly checked. Theincrease in the number of rules and data volume with every new process technology is raising accuracy,runtime and scalability issues. In ...
physical data. In fact it just contains coordinates of rectangles drawn in different colors (layers). The extraction process identifies the devices from the layout and generates a SPICE-like netlist and other files necessary to complete the design process. Before beginning a layout extraction you ...
The intent of this paper is to explain the varied kinds of DRCs (Design Rule Checks) that are encountered in the Physical Design flow. This paper will discuss the Metal DRC violations (7nm Technology) generally seen at the block level and outline the pra
