METHOD CARRIERS=2
#The impact ionization model for continuity equations allows the accurate prediction of
avalanche breakdown for many devices. Since impact ionization is a two-carrier process, the
following statement must be specified after setting impact ionization models.
solve outfile=quantumex01_temp.str master
#Specifies that any files read by this statement will be in a standard structure file rather
than the original PISCES format. Specify this parameter if you are using TonyPlot to
plot simulation results.
solve vgate=0 vstep=0.1 vfinal=5 name=gate ac freq=1e6 direct
#direct
Specifies that a direct linear solver will be used to solve the linear problem
during 3D simulation. By default, the ILUCGS iterative solver is used for 3D
problems.
MIXEDMODE 的开关特性：
solve vdrain=25 ramptime=1e-8 dt=1e-10 tfinal=1e-8 relative
#Specifies that the TSTOP value is relative to the current time value
| tstop Specifies the end of the time interval. If simulation begins at t=t0 and RELATIVE is specified, it will end at t=TSTOP+t0. |

只要仿真了频率 到时候就能用tonyplot 选中频率就行
