Hi Bobby,
It's better to either bottom post, or inline your comments as the thread
gets mangled in the archives.
There is MyHDL that may be of some use: <http://www.myhdl.org/>
"MyHDL turns Python into a hardware description and verification
language, providing hardware engineers with the power of the Python
ecosystem."
It supports synthesis from the Python RTL Models:
