STEAM

Table-based device modeling with polynomial interpolants. This code implements the 2017 ASPDAC paper titled "STEAM: Spline-based tables for efficient and accurate device modelling". Several other features were added to the code after the paper was published and are described in greater detail in a technical report "Table-based Device Modeling: Methods and Applications".

==== Using the package.

I have only tried setting up and running this package on Linux. It relies on softlinks and some other features which might not be readily available on Windows.

1. Get the most recent version of this package from github.com

        $git clone https://github.com/architgupta93/STEAM 
   

2. Get the submodules needed for polynomial interpolation. I developed them as stand-alone packages that could be used on their own and maintain separate version control for them.

        $git submodule update --init
   

   This should fetch two pacakges (as of 2019/03/13), polynomial-interpolation, and device-models. The first, as it name states, is a polynomial interpolation package, implementing splines, Lagrange and Barycentric-Lagrange interpolants.

3. Setup MAPP. Run the following to setup MAPP

        $autoconf
        $./configure
        $make
   

4. Open MATLAB (Octave might work too, but it doesn't work very well with MATLAB's class based programs.)

        >> start_MAPP
   

5. Goto the directory containing STEAM examples. It should be under STEAM/examples. Open/Run any of the scripts to see how STEAM and MAPP work.
