If PSpice encounters a convergence problem it inserts into
the output file a message that looks like the following.
The message always includes the banner (
ERROR --
convergence problem ...
) and the trailer (Last node
voltages tried were ...
). It cannot include all three of
the middle blocks.
ERROR -- Convergence problem in transient analysis at Time = 7.920E-03
Time step = 47.69E-15, minimum allowable step size = 300.0E-15
These voltages failed to converge:
V(x2.23) = 1230.23 / -68.4137
V(x2.25) = -1211.94 / 86.6888
These supply currents failed to converge:
I(X2.L1) = -36.6259 / 2.25682
I(X2.L2) = -36.5838 / 2.29898
These devices failed to converge:
