Working on fixbv for GSoC

I am interested in gsoc project- implementing back end compiler support for fixbv class. I had looked in fixed_point package and tested some of the example given. I also tested fixed datatype with abstract syntax tree package (AST). here when we create a floating point number compiler will convert it as fixed data type with fixed(value, min=-4, max=4, res=.125). test_file. i have used python 2.7 since importing fixed_point package throws errors in python 3.4. I also want to know what should be next step toward the project.

with regards.
