1）PR Flow使用UPF来描述这样的行为需求2）把PD_VDDSW单独做模块实现并且处理好这根特殊信号的AON buffer一般来说，我们通过upf文件来告诉工具每个instance，每个pin的power domain信息。所以，当我们成功读入UPF文件后需要检验下一些特殊信号的power domain属性。如果有错误就需要及时对UPF文件进行修正。
Godwin Maben, Synopsys Fellow, demostrates how to translate a high-level power intent from CSV to a consumable UPF across a typical ASIC design flow using Verdi UPF Architect.This is a modal window. The Playback API request failed for an unknown reason Error Code: VIDEO_CLOUD_ERR_UNKNOWN ...
The Tcl command “create_power_domain”, for example, is used by UPF-aware tools to define a set of blocks in the design that are treated as one power domain that is supplied differently to other blocks on the same chip. The idea behind this type of command is that power-aware tools ...
综上所述，Low power design项目需要综合考虑多个方面，包括低功耗设计方案、低功耗单元选择、UPF代码编写、后端流程配置以及持续验证与优化等。通过不断学习和实践，可以不断提升在低功耗设计方面的能力和水平。
Low Power Design is a collection of techniques and methodologies aimed at reducing the overall dynamic and static power consumption of an integrated circuit (IC).
What Is Needed to Solve Challenges from UPF Low Power Design? From the design engineer’s point of view, it is natural to guarantee the functionalities of designs are correct. However, designs today do not only talk about functions, but low power consumption is also a requirement...
在floorplan前，引入UPF'文件，规划不同电压域的位置和面积。针对每个电压域，分别进行floorplan和powerplan。特别关注可关断电压域的powerplan，需要处理第二层电源栅极（second pg）问题，以平衡面积、绕通性、DRC和IR drop的要求，同时最小化对时序的影响。在完成place、CTS、Route步骤后，需特别注意lvl...
2 UPF The UPF specification is in ASCII format that can be used to specify low power directives that encompass all aspects during the design flow. The power specification provided in a UPF file can be used by simulation, synthesis, equivalence checking, physical design and physical ve...
UPF包括:电压域的规定,电源网络,Power state,low power cell的定义。网上对于UPF语法的介绍也单独有文章。 3. DC flow 完成UPF代码,就可以在DC阶段将UPF文件吃进来,并规定好各电源线的电压,利用insert_mv_cells命令插入lvl,并通过check_mv_design检查UPF定义是否有问题,lvl是否漏插。跑完DC flow还要用low power...
我在看资料的时候,发现很多做power的人需要对UPF IEEE1801 等东西的规格有很多的了解,然后还需要看userguide。但是我感觉不是专门做power的人,其实从电路结构和电路原理了解一下现行的low power 的技术是什么样就差不多了。 知道底层原理是什么样, 我们debug的时候心里有数就行。 真的去扒各种UPF CPF command之间...
