Hi ,
This error along with the solution is documented in Hspice user manuel.
Consult page 980 solution: 293
Problem:
1. A voltage source with the inductor connected to the same point.
2. A voltage source with an inductor connected directly across its
nodes.
3.Two or more inductors connected in a loop with nothing to limit the
current.
Solution: connect a small resistor, e.g:1nano ohms, in series.
