We love open-source code and we love VHDL/Verilog.
This repository contains approximately 860 free and open-source VHDL/Verilog IP cores. All these cores have been carefully "scraped" from opencores.org using this open-source Python script.
A cool searchable index of the whole repo is available from www.freerangefactory.org/cores.html
Cores can be fetched idependently by conveniently downloading only the branch you are interested in. These are the available branches:
