 1 Noise analysis (NOISE)
    The noise analysis does analysis device-generated noise for the given
 circuit. When provided with an input source and an output port, the analysis 
 calculates the noise contributions of each device (and each noise generator 
 within the device) to the output port voltage. It also calculates the input 
 noise to the circuit, equivalent to the output noise referred to the 
 specified input source. This is done for every frequency point in a specified 
 range - the calculated value of the noise corresponds to the spectral density 
 circuit. When provided with an input source and an output port, the analysis
 calculates the noise contributions of each device (and each noise generator
 within the device) to the output port voltage. It also calculates the input
 noise to the circuit, equivalent to the output noise referred to the
 specified input source. This is done for every frequency point in a specified
 range - the calculated value of the noise corresponds to the spectral density
 of the circuit variable viewed as a stationary gaussian stochastic process.

    The operating point sweep analysis determines the values of output
 variables while one or two specified independent voltage or current source is
 stepped over a user-specified range and the dc output variables are stored
 for each sequential source value.
 3.1 Enhancements
  Added resistance and temperature sweep.
 4 Pole-zero analysis (PZ)
    The pole-zero analysis computes the poles and/or zeros in the small-signal 
 ac transfer function. The program first computes the dc operating point and 
 then determines the linearized, small-signal models for all the nonlinear 
 devices in the circuit. This circuit is then used to find the poles and zeros 
 of the transfer function.

    The distortion analysis computes steady-state harmonic and intermodulation
 products for small input signal magnitudes. Not all devices are supported.
 6 Small Signal frequency response analysis (AC)

 and determines linearized, small-signal models for all of the nonlinear
 devices in the circuit. The resultant linear circuit is then analyzed over a

 7 Sensitivity analysis (SENS)
    Ngspice will calculate either the DC operating-point sensitivity or the AC
 small-signal sensitivity of an output variable with respect to all circuit 
 variables, including model parameters. Spice calculates the difference in an 
 output variable (either a node voltage or a branch current) by perturbing 
 small-signal sensitivity of an output variable with respect to all circuit
 variables, including model parameters. Spice calculates the difference in an
 output variable (either a node voltage or a branch current) by perturbing
 each parameter of each device independently.
 8 Transfer function analysis (TF)
    The (small signal) transfer function analysis computes the dc small-signal
 value of a transfer function (ratio of output variable to input source), 
 input resistance, and output resistance is also computed as a part of the dc 
 value of a transfer function (ratio of output variable to input source),
 input resistance, and output resistance is also computed as a part of the dc
 solution.
 9 Transient analysis (TRAN)
    The transient analysis computes the transient output variables as a
 function of time over a user-specified time interval. The initial conditions 
 are automatically determined by a dc analysis. All sources which are not time 
 function of time over a user-specified time interval. The initial conditions
 are automatically determined by a dc analysis. All sources which are not time
 dependent (for example, power supplies) are set to their dc value.
 10 Periodic steady state analysis (PSS)
     The periodic steady state analysis computes solutions for oscillating 
 	 circuits. Currently only the autonomous case is implemented.

 1.3 Why resurrecting Berkeley's Spice?
  Berkeley's Spice can be considered the father of most circuit
  simulators available today. It is an old but still good piece of
  software, it may not be the fastest or the most reliable but it's
  free, it's available in source code and most of the electrical
  simulators inherited it's syntax. Spice3 is based on proven numerical 
  algorithms (most commercial implementations have only strengthened 
  them), implements most of the models for MOSFET submicron design 
  simulators inherited it's syntax. Spice3 is based on proven numerical
  algorithms (most commercial implementations have only strengthened
  them), implements most of the models for MOSFET submicron design
  and has a powerful set of analyses. The readily availability of
  its source code in the past made this simulator the de-facto standard.
 1.4 What is the project's goal?
  Ngspice is both a maintenance and enhancement project. It is a maintenance
  project because it aims to provide the free EDA community the best spice3
  simulator available. This means fixing bugs, adding new features but always
  in the spice3 framework. Achieving compatibility with commercial spice based 
  in the spice3 framework. Achieving compatibility with commercial spice based
  simulators and provide users the latest devices models are important goals

     Creating ngspice with MINGW is a straight forward procedure,
 if you have MSYS/MINGW installed properly. You will need some enhancements

 Some links are given below which describe the procedures.
     Installing from the tarball, e.g. ngspice-25.tar.gz, is now simple: After
 expanding, you may just run ./compile_min.sh from the ngspice-25 directory.
     The default installation location of ngspice is the Windows path
 C:\spice. The install path can be altered by passing --prefix=NEWPATH
 as an argument to ./configure during the build process.
     Put the install path you desire inside "", e.g. "D:/NewSpice". Be  
 careful to use forward slashes "/", not backward slashes "\" (something 
 still to be fixed).  Then add --prefix="D:/NewSpice" as an argument to

 01- ngspice Files
  Ngspice does not (yet) have support for loading models at run time, every
  model must be included at compile time. Then, adding a new model into 
  model must be included at compile time. Then, adding a new model into
  ngspice is a process that cannot be completely automated. Some files need
  to be edited by hand.
  01.01 What ngspice need to know of a new model ?
  First you have to assign your new model a "device type". As you probably
  know, ngspice recognizes the type of a device by the first letter in 
  know, ngspice recognizes the type of a device by the first letter in
  device's name in the netlists ("r" for resistors, "q" for BJT, "m" for
  mosfets and so on). Then the first thing you have to find is the correct
  type for your new device (let's call this device_type).
  Since there can be more than one model for each device type, another
  parameter you have to set is the device_level, which must be unique
  for each device type.
