Open-source EDA shows promising potential in unleashing EDA innovation and lowering the cost of chip design. This paper presents an open-source EDA project, iEDA, aiming for building a basic infrastructure for EDA technology evolution and closing the industrial-academic gap in the EDA area. iEDA now covers digital chip logic synthesis (including logic optimization, technology mapping, automation test pattern generation), the whole flow of physical design (including Floorplan, Placement, CTS, Routing, Timing Optimization etc.), and part of the analysis tools (Static Timing Analysis and Power Analysis). To demonstrate the effectiveness of iEDA, we implement and tape out five chips of different scales (from 700k to 100M gates) on different process nodes (110nm and 28nm) with iEDA. iEDA is publicly available from the project homepage http://ieda.oscc.cc.
“一生一芯”(https://ysyx.org)由中国科学院大学于2019年发起,至今累计报名人数已逾12000人,覆盖全球900余所高校及科研院所。
“一生一芯”专注培养学生独立解决问题的能力,以及“计算机软硬件系统协同设计能力”和“芯片全链条设计能力”,坚持开放性和公益性,兼顾“大规模”和“高质量”。面向全球芯片设计爱好者,不限学校、专业和年级,全年开放报名(报名和学习均免费),随到随学(可零基础),并为学生提供免费或低成本流片机会。
“一生一芯”指导学生从零开始设计一款RISC-V处理器芯片,在其上运行自己开发的系统软件和演示程序,并通过开源EDA工具和开源PDK完成物理设计流程。“一生一芯”的学习内容课程覆盖计算机系统全栈抽象层,从应用程序、运行时环境、简易操作系统、指令集,到处理器微结构设计、RTL开发、综合、布局布线、时序分析,最终生成晶体管级的可流片GDSII版图。同时,“一生一芯”为达到指定学习目标(完成B阶段)的在校生,提供免费流片机会。
