160Gbit/s交叉连接芯片总体方案设计
摘要
首先在明确40Gbit/sSDH(STM 256)光纤通信设备要求的基础上
确定了芯片与外围电路的电路、功能和时序接口
制订了满足设备需要并利于ASIC实现的芯片技术规范;其次
进行了芯片的总体方案设计
按照自顶向下的全正向设计方法进行了芯片的逻辑结构设计
并合理安排了芯片的寄存器结构;行为级仿真结果表明
方案是可行的.
Abstract
This thesis focuses on the toplevel design of the digital cross connect (DXC) chip. Based on the precept of 40 Gbit/s SDH (STM-256) fiber-optical communication devices & system
the design target of the chip is specified at the beginning
the functions
circuit and timing interface are clearly defined. Then the logic architecture is discussed with top to down design method. At last
