为什么会出现如下问题
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
请高手指点一下!
