In an analog circuit simulation to calculate the voltage/current at any node, simulator requires information about electrical characteristics of each device.
This is provided in the form of a set of equations and parameters to the simulator.
set of equations used to describe the device characteristics is called model eg: BSIM3
parameters are the variables input to these equations so that the device characteristics from simulation are same as observed in actual measurement for a particular device.
eg., of parameters: threshold voltage, mobility.
Determining these parameters for a particular device to match simulation and measurement is called parameter extraction.
I have a mos fabraicated in silicon. I have some measured data for particular vgs and vds.
I use the measurement data and model and extract parameters so that the simulated result is same as measured data.
Then using this model I can simulate the device for any vgs and vds and know the output current.
This is the need of device modeling.
Proper model implies it reflects the fabrication technology exactly.
