I have uploaded the source code to my M.Sc thesis project. The main reason why this is worth checking out is because of the use of SystemVerilog features which were used in the feature. The features include packages, typedef, interfaces, modports, always_comb blocks, and a good amount of parameterization. Considering most of this work was done in 2006-2007, I think its pretty impressive.
