$solvetimestep is a command for solving the transient behavior of the device. The format is

$solvetimestep
steptype
parameters(1) parameters(2) ....    

The number of parameters depeding on step type. Now we have 3 step types

Steptype  = 1:  
δt,ttotal,vg0
vg=vg_end for t<0, for t>0, vg=vg0
Steptype  = 2:  
δt,ttotal,vg0,A0,ω,c0
vg=vg0+A0×sin(2πωt+c0)
Steptype  = 3:  
δt,ttotal,vg0,A0,ω,c0
vg=vg0+int(A0×sin(2πωt+c0))
