GALS设计方法-微子学与固体电子学专业毕业论文.docx

Abstract Abstract OALS(Olobally Asynchronous Locally Synchronous)method well with the design of synchronous and asynchronous design method,has the advantage,especially in resolving the issue of time domain and update the reusability of modules such as in a unique position．Its design thinking is that the various functional modules are designed in synchronized manner．Then various synchronous modules are wrapt by synchronous—asynchronous conversion interface，and each module communicates asynchronously． In this thesis，a谢de range of study is made in asynchronous circuit design principles，GALS system principles，methods and module design etc which lay the foundation for GALS design． The thesis focus on the work：a variety of C-Element(two-input C dement, three-input C dement,set-C element and reset-C element)circuits are introduced．The working principles of relevant circuits are analyzed。The models of transistor level ale realized and simulated．The layout of three-input C dement is presented．Also，several CMOS implementations of set—C clement and reset-C element are proposed．A better implementation is concluded fzom the curves of energy consmption,rising delay and falling delay．GALS asynchronous wrapper circuit is designed,including synchronous-asynchronous communication ports and stretchable clock controller．With about 900 transistors，a point to point GALS system is successfully implemented． All simulation ofthis thesis is based on the 0．251am typical CMOS process。 Keyword：Asynchronous Circuit Handshake Protocol C Element GALS System  蔼安电子辩技大学 学位论文独铡性(或刽新性)声明 秉承学校严谨的学风和优越的科学道德，本人声明所望交的论文是我个人 在导师指导下进行驰磷究工{乍及取褥的研究成梁。尽我所知，除了文中特别热以 标注鞠致谢孛甄罗列豁态容鼓癸，论文孛不惫含冀蹙天己筑发表或撰写过翡讶究 成果；也不包含为获得西安电予科技大学或其它教育机构的学位或证书耐使用过 的材料。与我一同工作的同志对本研究所做的任何贞献均融Ⅲ侄论文中做了明确的 说瑟并表示了{囊}意。 申请学位论文与资料若有不实之处，本入承担一讶酶法律责任。 西安电子科技大学 关于论文使用授权的说明 本人完全了解嚣安毫子科技丈学毒关爨餐蠲建羁学缀论文熬规定，即：戮究 生在???攻读学位麓闻论文工露斡知识产权单豫属西安毫予科技大学。学校有权僳 留邀交论文的复印件，允许查阅和借阅论文；学校可以公布论文的全部溅部分内 容，可以允许采用影印、缩印或其它复剩手黢保存论文。湖时本人保证，毕业后 结台学位论文研究课遂再撰写鹣文章一律豢名单霞为莲安惫予藉蓑大学。 (保
