基于Hyperlynx的DDR3时序的研究与仿真
Study and Simulation of DDR3 Timing Based on Hyperlynx
为保证系统能正常稳定工作,在PCB设计时进行精确的时序分析和控制显得非常必要;分析了源同步系统的时序,并根据分析结果得出时序约束不等式。针对一嵌入式系统,采用Mentor Graphics公司的仿真工具Hyperlynx进行信号完整性仿真,获得时序不等式中的关键参数,通过对时序不等式的计算,得出了控制系统工作时序的约束。最后利用Hyperlynx进行布线后仿真,验证研究结果的正确性。这一设计方法也适合于其他高速数字系统的时序设计。
For the sake of the stability of the system, it is quite a necessity to proceed some precise timing analysis and control during the design process of PCB, analyzing the timing of the source sync system and deriving the inequality of timing constraints from the results. As for the embedded system, Hyperlynx of Mentor Graphics Co., Ltd. is utilized to do the SI simulation in order to obtain the key parameters in the Timing Inequality. By calculating this timing inequality, the timing constraints of the control system. Ultimately, with the post-route simulation by Hyperlynx, the result is verified. The method elaborated previously is also applicabel to other timing designs of high speed digital systems.
