Study On MCS-51 MicroController's Reverse Anatomization And Top-Down Design

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.
