請教各位大蝦：
      我用orcad里的pspice仿真電路時總是出這樣的錯誤：
     ERROR -- Convergence problem in transient analysis at Time =  6.006E-03
         Time step =  1.025E-15, minimum allowable step size =  7.000E-15

  These supply currents failed to converge:

    I(X_IGBT1.XDIO.EXJ)       =   114.24uA  \   113.99uA
    I(X_IGBT1.XDIO.EJUNCT)    =    2.450uA  \    2.455uA
    I(X_IGBT1.XDIO.VDXJ)      =  -114.24uA  \  -113.99uA
    I(X_IGBT1.XDIO.VIJCT)     =   -2.450uA  \   -2.455uA
請問各位大師是怎么回事??？？？在線等回復??！
