针对片上网络路由器间相邻长互连线串扰导致信号抖动大的问题,基于互连线有效负载解析模型,提出了一种通过相邻信号的比较得到有效负载大小,调整信号驱动强度,从而保持传播延迟时间稳定,抑制信号抖动的方法.与缓冲器驱动模式相比较,在驱动级具有相同宽长比的情况下,当互连线的长度为2mm、宽度和间距均为0.4μm时,信号的相对抖动减小了29.6%,有效提高了长互连线的最高工作频率.

This paper proposes a new method which aims at reducing big jitter caused by adjacent interconnection line crosstalk. Based on an analytical model of the interconnection payload, the method adaptively adjusts the signal drive strength according to the payload size to maintain the stability of communication delay, so as to effectively limit signal jitter. Compared with the drive mode of the buffer, under the condition of the same W/L of the driving buffer, the relative signal jitter decreases 29.6 percents when the length, wide and space of interconnection lines are 2mm, 0.4μm, 0.4μm, respectively, thus effectively improving the maximum operating frequency of long interconnects.
