【摘要】 在过去的几十年中，电子工业飞速发展。集成电路制造工艺已经通过了深亚微米极限，使得IC设计者可以在单个芯片上集成上千万个晶体管，集成电路进入了片上系统(SOC)王国。IP核的设计也就越来越受到理论界和工业界的关注，而MCS—51单片机芯片应用非常广泛，同时掌握MCU设计技术也非常重要。因此，本论文对MCS—51单片机芯片进行了反向解剖和正向设计的研究。 本论文的目的是设计MCS—51单片机芯片，主要工作和取得的成果如下： ①对MCS—51单片机进行分析研究，包括MCS—51单片机工作原理、指令系统、时序分析、特征提取等。并在此基础上完成反向解剖和正向设计MCS—51芯片。 ②对MCS—5l单片机进行反向解剖，根据解剖芯片的照片提取电路图，并利用L-Edit完成版图设计。版图设计过程中要进行设计规则检查、电气规则检查等。完成逻辑图划分、整理功能块以及版图与逻辑图一致性验证后，进行硬核仿真，以便于确保芯片功能完全正确。 ③对MCS—51单片机进行正向设计，包括系统划分、编写代码、RTL级仿真与综合、门级仿真等。在设计的不同阶段分别使用了Cadence、Modelsim、Synplify6.0、MaxplusⅡ10.0等EDA工具。同时基于MCS-51单片机的反向解剖讨论了优化正向设计，减少综合后门数的设计方法。 总之，通过反向解剖和正向设计，我们得到一个即将投入市场的MCS—51单片机芯片，初步实现一个可以重复使用的硬核和软核模块。更多还原

【Abstract】 The worldwide electronics industry is rapidly moving forward over the past decades. As silicon technology has crossed the deep-submicron threshold,we can design tens of millions of transistors on a single chip. That is to say semiconductor has entered into the realm of "System on a Chip (SoC)" . The research on the technology of IP core design is concerned by both research society and industry world. Because of the wide use of MCS-51 Microcontroller and the important meaning of MCU core design,we study on MCS-51 reverse anatomization and Top-Down DesignThe goal of this article is to design a MCS-51 Microcontroller chip. The Main work and achievements are as followSMCS-51 Microcontroller is studied. The result of the research is included MCS-51 Microcontroller work princip instruction system timing analysis feature picking up;etcMCS-51 Microcontroller chip has been anatomized. Based on the chip’ s photo,we get the whole schematics and finished the layout design. During the layout design,using L-Edit tools,DRC and ERC have been done. The design of the chip is totally accomplished by detail simulation.The design of MCS-51 Microcontroller is followed the Top-Down design way,including system partition coding (VHDL) RTL simulation synthesis,gate level simulation ect. Different EDA tools are used in different phase,such as Cadem Modelsirru Synplify 6.0 Maxplus II 10.0 and so on. The technology of optimization design based on MCS-51 Microcontroller reserve anatomization is also discussed.In a word,the chip will be sold openly in the market soon. The reuse hardware core and software core are primarily succeeded.更多还原
