為什么會出現(xiàn)如下問題
ERROR -- Convergence problem in transient analysis at Time =  427.5E-06
         Time step =  8.750E-15, minimum allowable step size =  10.00E-15

  These voltages failed to converge:

    V(N08147)                 =    14.58uV  \    9.178uV
    V(N05995)                 =    20.32uV  \    12.38uV

  These supply currents failed to converge:

    I(X_U1.x119.x2.vs1)       =    -9.55nA  \   -5.346nA
    I(X_U1.x119.x2.vdrop)     =   -8.308nA  \   -4.657nA
請高手指點一下！
