DDR 测试、验证和调试

新一代内存技术如 DDR4 和 LPDDR3,带来更快的速度、更低的 I/O 电压和各种外形,可满足不同的应用需求。 结果产生新的调试和验证挑战,包括更紧凑的余量、更快的边沿速率和复杂的总线协议。

泰克提供最完整的全套工具进行内存验证和调试:

  • DDR 电气验证:
    捕获、测量和检定 DDR 内存接口信号行为、抖动、眼图大小、交叉、选通/时钟对准、误码。
  • DDR 逻辑验证:
    捕获和测量 DDR 内存接口的数字逻辑状态,执行总线周期的定时和协议分析。
     
  • DDR 协议性能验证:
    捕获和分析总线命令、控制时基系列、将结果与内存接口规范比对,并分析作为总线利用率和性能指标的总线流量。

Title
DesignCon 2015 Paper - Designing High Performance Interposers with 3-port and 6-port S-parametersThis technical paper explains how multiport S-parameters can be used to validate memory interposer design cases. This helps memory designers understand some of the performance characteristics that can be inferred from S-parameters, as well as some of the interactions between the interposer and the device under test and probing system; leading to more accurate validation efforts on very fast memory systems utilizing DDR4 or LPDDR4.
