VHDL/Verilog IP CORES Scripts

This repository contains few Python scripts capable to connect to the website opencores.org and download from it approximately 4.5GB of VHDL/Verilor IP cores. Downloaded data is saved locally and, in a second step, uploaded to github. An index.html file containing an index of the available IP cores is generated.

All downloaded IP cores, once saved locally, are then uploaded on this guthub repository:

https://github.com/fabriziotappero/ip-cores

The "ip-cores" repository accounts for approximately 800 projects spread in 16 categories. There is a branch for each IP project. Since the whole repository is very large, you are advised to check out only the branch that you might interested in.

Available Python scripts:

opencores_scraper.py downloads all opencores.org projects locally (in a local folder in your PC) and generate a n index file index.html.

local2github.py analyze a local folder and upload its content to the github repository https://github.com/fabriziotappero/ip-cores
