$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:
vg=vg_end for t<0, for t>0, vg=
Steptype = 2:
vg=vg_0 + A_{0} \times sin\left( 2\pi \omega t + \omega_0 \right) for t<0, for t>0, vg=
Vgnow= vg0+ vga*0.5*sin( 2*pi*freW0*tnow +vgphase)
Steptype = 3:
