    HIGHLIGHTS

    产品要点

    • 设计可控阻抗线路的堆叠结构和线路几何结构
    • 优化重要的指标:芯片间链路中的后均衡器眼图参数
    • 确定企业 PCB 或封装工具中的自动路由器的约束条件

    W2307EP 互联工具箱元件包含两个实用工具,用于设计高速互联(分别是传输线和过孔转换)。

    互联工具箱实用工具

    互联工具箱中的实用工具支持您使用重要的度量值(后均衡器眼图参数)优化您的印刷电路板(PCB)堆叠和传输线几何结构。其他工具将向您展示线路中的减损,例如损耗、频率滚降和阻抗变化,但对于如今的多千兆位芯片间链路而言,这些指标还是不充分的。在使用现代串行器/解串器(SerDes)的信号处理功能减少线路减损之后——例如发射机(Tx)预加重和接收机(Rx)均衡——眼图参数成为了最重要的度量值。事实上,现代芯片 I/O 信号处理的全部意义在于可使您使用低廉的材料,并且始终使眼图张开。

    CILD End-to-End Schematic

    图 1. 通过把线路类型与统计眼图通道仿真整合在一起,您可以使用重要的度量值——例如后均衡开眼的高度和宽度——优化您的可控阻抗线路。

    互联工具箱允许您在候选线路周围放置发射机和接收机,构成一个完整的 ADS 通道仿真器或 ADS 瞬态仿真器原理图,从而实现上述目标。特别是,通道仿真器的统计模式可在数秒钟内在设计空间的每个点上生成超低的 BER 轮廓。您能够快速扫描参数以查看效果,例如宽度和间隔。

    图 2. 在线路宽度上进行前均衡和后均衡眼图扫描。前均衡和后均衡分别位于顶端行和底端行。1 mil宽度位于右侧,5 mil 位于中心,而 9 mil 位于左侧。

    过孔设计人员实用工具

    过孔设计人员实用工具使用户可以快速设计单端和差分的过孔转换。过孔模型可以完全通过参数表示,并利用高度精确的三维全波形有限元方法(FEM)仿真技术来进行分析。用户可以在此实用工具(混合模式 S 参数)中查看仿真结果,并导出参数化模型供通道仿真使用。提取的模型包含一个精简的数据库,其中存有大量参数化结果,可在仿真数据之间实现高效内插。

    利用参数化的传输线和过孔转换,高速通道设计人员可以协同优化重要指标(眼图高度和眼图宽度)。
