基于DDR3的PCB设计及仿真

Simulation and Design of PCB Based on DDR3

随着计算机技术的快速发展,高速存储器技术已得到广泛应用,目前市场上主流应用的内存为DDR3存储器,并且数据传输率一再被提升。在这种情况下,对PCB设计都提出了更高的要求,同时也增加了PCB设计需要考虑的参数。随之出现的存储器的仿真技术,通过对影响信号质量的关键因素的分析,实现对信号完整性的仿真分析,从而节省了PCB设计时间及开发成本。

With the development of computer technology, the high speed memory has been widely used. At present, the DDR3 memory is widely used, and the data transmission rate is promoted again and again. In such a case, it has higher requirement for signal quality and timing, at the same time, it also adds the parameters to be considered for PCB design. The simulation technology of memory appearing subsequently can shorten the design cycle of memory simulation and improve the development level. Starting from the basic theory of simulation technology, this paper introduces briefly the key elements affecting the signal quality, and explains briefly the analysis thinking and simulation method combining with living example.
