I new to hspice, i searched on the hspice docs, but still cannot clear about this option. What does this option actually effect on simulation.

.param dummy=1
.dc dummy 1 1 1

Please help me on this! Thanks very much!

Basically this will run the simulation with dummy = 1.

The .dc command defaults to a linear scale, but you've put 1 as the starting point, ending point, and increment.

If you want to run the simulation with dummy = 1, then 2, then 3 for example use .dc dummy 1 3 1 (i.e. 1 to 3 incremented by 1)
