fixed point modeling tools

Hello,

For those of you who do DSP modeling in Python, I've recently released a package that supports fixed point arithmetic. The existing open source tools are lackluster and MATLAB doesn't nicely fit into our simulation/testing workflow. Just trying to get the word out for a higher adoption rate!

Documentation is here:
https://fixedpoint.readthedocs.io

Gihub repo is here:
https://github.com/Schweitzer-Engineering-Laboratories/fixedpoint

Compatible with Python 3.8.0 and later. Install from PyPI with pip:
pip install fixedpoint

Interesting. When I went looking some months ago I found spfpm
(https://pypi.python.org/pypi/spfpm) which was fairly recently
updated. So how does yours compare? At least compatibility seems tighter
for yours as spfpm works with Python 3.3 and later.

My need was mostly for conversion of floats to VHDL sfixed/ufixed
formats for FPGA testing but in the end I didn't need it.
