Hi Neil, Yes, we use Python 3 for our CASPER toolflow (with a virtual python environment) and our comms package casperfpga is written in Python 2.7. We are working on a Python 3 version. The tooflow consists of a frontend, middlend and backend. The frontend, middlend and backend all use Python. In basic terms, the front end uses python to extract critical information from the Simulink file and yellow blocks. The middlend is then run to create the top.v and the rest of the RTL connects using python and the backend uses python to call Vivado to do the compile -creates tcl scripts and xdc files etc. Obviously this is a simple explanation and the python does a lot more.
There is no cost for python - your only costs will be Matlab/Simulink (speak to your supplier for a quote) and Vivado license (speak to supplier for a quote). No other costs are needed. SARAO is working on a toolflow that supports Vitis, which is completely free and the libraries are open source. We are targeting the Alveo platforms, which means the Vivado license is included in the free web pack license, so no Vivado license is needed. Just a Matlab/Simulink license. We do plan to phase this out at some point, but it might take a long time. A lot of our CASPER DSP libraries have been around a long time and it wouldn't make sense to get rid of them yet.
