加油机论文：亚微米数字集成电路约束及收敛方法研究【中文摘要】随着集成电路技术的快速发展,芯片加工工艺不断缩小,电路设计规模不断扩大,同时芯片功能和性能要求越来越高。在这种情况,芯片的约束分析变得极为复杂,约束收敛越来越难。因此,如何正确且快速地实现芯片约束收敛是深亚微米集成电路设计所需考虑的重要问题。本文在山东省信息产业厅发展专项资金项目“税控加油机控制系统集成电路芯片设计”的支持下,对数字集成电路的约束原理和约束方法进行深入的研究,然后对税控加油机油量控制芯片GVC (Gas Volume Controller)进行约束分析,最后在Synopsys ASIC设计平台上实现该控制芯片的版图设计,并确定芯片约束收敛的方法。本论文的主要工作包括以下几个方面：1、研究芯片约束的原理和方法,并对税控加油机油量控制芯片进行约束分析,主要包括时序约束分析、面积约束分析和功耗约束分析；2、制定芯片综合优化策略,并在约束作用下完成税控加油机油量控制芯片RTL代码到门级网表的转换；3、实现税控加油机油量控制芯片的物理设计,包括布图规划、布局、时钟树综合和布线,确定芯片的约束收敛方法；4、为了提高制造良品率,对芯片进行可制造性设计,包括天线修复、添加fillercell和冗余金属填补等；为准确计算芯片互连线的延迟,对版图进行RC寄生参数抽取；5、芯片约束收敛验证,包括物理验证,静态时序分析,功耗分析,电压降/电子迁移分析以及等价性验证等。本论文基于Chartered 0.35微米逻辑工艺,完成了税控加油机油量控制芯片从综合到版图的设计工作,芯片的所有约束都得到了收敛,并成功流片。经验证,芯片能够实现税控加油机控制系统的所有加油控制功能和数据查询功能等,解决了当前国内税控加油机控制系统存在的不足,填补国内税控燃油加油机控制芯片的空白。【英文摘要】With the speedy development of integrated circuit technology, the process of chip is shrinking and the scale of chip is expanding. At the same time, the requirement of chip function and performance become stricter. In this case, the complexity of chip constraints analysis is raising gradually. Simultaneously, its more difficult to make the constraints convergent. So how to accurately and rapidly realize chip constraints convergence is the important problem of deep-submicron IC design. Basing on the development special fund project “Integrated Circuit Design of Revenue Fuel Dispensers Control System” of Shandong Provinces Information Industry Department, this paper systematically researches the principle of the chip constraints and takes the GVC (Gas Volume Controller) chip for example to do chip constraints analysis. Then, with the Synopsys ASIC design tools, this paper realizes the GVCs layout design, and introduces the constraints convergence methods and verification methods in detail.The main work in the thesis is as follows:1. Research on the chips constraints principle and methods, and finish GVCs constraints analysis;2. Formulate GVCs compile optimization strategy, and in the constraints function complete GVCs RTL code to netlist conversion;3. Realize GVCs layout design, include floorplan, placement, cts, route, and determine the constraints convergence methods;4. In order to improve the yield of chips for manufacturing, finish DFM to GVC design; To accurately calculate wire delay, make RC parasitic parameters extraction for GVC layout;5. Chip constraints convergence validation, include physical verification, static timing analysis, power analysis, IR-drop/EM analysis and equivalence checking.With Chartered 0.35 micron technology, this thesis completed GVC RTL synthesis to layout design. All the constraints of chip had been convergent, and chip was successfully taped out. Through verification, chip could realize control and data query function of revenue fuel dispensers control system, improvd the deficiencies of current domestic revenue fuel dispensers control system, and filled control chip blank of domestic revenue fuel dispenser.【关键词】加油机 控制系统 约束分析 静态时序分析 版图设计【英文关键词】Fuel Dispenser Control System Constraint Analysis STA Layout Design【目录】亚微米数字集成电路约束及收敛方法研究中文摘要8-9ABSTRACT9符号说明10-11第一章 绪论11-151.1 研究背景111.2 集成电路的设计流程11-131.3 论文的组织结构13-15第二章 税控加油机油量控制芯片约束分析15-272.1 税控加油机油量控制芯片概况15-182.1.1 GVC功能描述15-162.1.2 GVC系统架构16-182.2 GVC芯片的约束类别18-192.3 GVC功能模式的时序约束分析19-272.3.1 时钟建模19-202.3.2 I/O端口的时序约束20-232.3.3 I/O端口的驱动和负载特性23-242.3.4 时序例外约束24-27第三章 逻辑综合策略与实现27-353.1 逻辑综合273.2 逻辑综合策略27-283.3 GVC自顶向下综合流程28-323.4 GVC综合结果分析32-35第四章 版图设计35-574.1 数据准备35-384.2 布图规划(Floorplan)38-444.2.1 GVC面积和IO PAD的选择39-414.2.2 GVC PAD和宏模块的布局41-424.2.3 GVC电源网络设计42-444.3 布局(Placement)44-474.3.1 GVC布局流程44-464.3.2 GVC布局结果46-474.4 时钟树综合(CTS)47-514.4.1 GVC时钟网络性能参数约束48-494.4.2 GVC时钟树综合流程49-504.4.3 GVC时钟树综合结果50-514.5 布线(Routing)51-544.5.1 GVC布线流程51-534.5.2 GVC布线和可制造性设计结果53-544.6 物理验证54-574.6.1 设计规则检查(DRC)55-564.6.2 版图与原理图的一致性检查(LVS)56-57第五章 功耗分析和电源完整性分析57-655.1 功耗分析57-615.1.1 IC系统中的功耗57-585.1.2 GVC门级功耗分析流程58-605.1.3 GVC功耗数据分析60-615.2 电源完整性分析61-655.2.1 电压降和电迁移61-625.2.2 GVC电压降和电迁移分析流程62-635.2.3 GVC电源网络数据分析63-65第六章 静态时序分析和形
