If I use a spice model file from fab, and draw sch myself,then use ADE to do the sch->netlist and then simulate the transient/ac of ckt with spectre or hspice, are parasite caps of mos(Cgs,Csb,Cgd,.etc) considered in the simulation?

Of course I cannot see the parasite on the sch, but will spice includes them automatically for me?

thx.

Added after 1 minutes:

I mean just simulation with netlist from orignal sch, not post simulation after lpe
 

yeah spice will incle those parameters

Added after 55 seconds:

if only the model from the fab takes care of
 

can I verify that by myself?
like can I print out the value of them(just like .op and then get all the small signal parameter)
 

try to change the drain and source area and perimeter with the same MOS size and compare results

Re: Does spectre/hspice include mos parasite cap&res in

You may choose Results -> Print -> DC operating points

Then choose your device in your schematic and it will list all the intrinsic components of the MOS

hello, if you use hspice for simulation,you also can use the element template listing
to examine the parasite parameters in the transient simulation.
For the detail information, you can refer to the hspice manual.
