器件型号:LM25143-Q1

工具与软件:

我正在 TI 的 PSPICE 中使用 LM25143RHA-TRANS 模型、并收到以下错误:

  These voltages failed to converge:

    V(X_M2.8)                 =    23.01mV  \    22.71mV
    V(X_M4.8)                 =    23.01mV  \    22.71mV
    V(X_U1.X_U7_U624.YINT)    =    91.70uV  \   -3.209pV
    V(X_U1.X_U7_U629.YINT)    =    91.70uV  \   -3.209pV
    V(X_U1.X_U5_U637.YINT)    =    91.70uV  \         0V

  These supply currents failed to converge:

    I(X_U1.X_U7_U624.E_ABMGATE) =   -91.70uA  \    3.209pA
    I(X_U1.X_U7_U629.E_ABMGATE) =   -91.70uA  \    3.209pA
    I(X_U1.X_U5_U637.E_ABMGATE) =   -91.70uA  \         0A
    I(X_U1.V_UCLK1_V45)       =   -2.842uA  \   -2.834uA
    I(X_U1.V_UCLK2_V45)       =    6.404uA  \    6.419uA

  These devices failed to converge:
    X_U1.X_U7_U624.E_ABMGATE X_U1.X_U7_U629.E_ABMGATE X_U1.X_U5_U637.E_ABMGATE

U1是我尝试仿真的模型、但我不知道如何解决与其他"U"参考设计相关的问题。
