 **Future** fully open source Test Tile
 --------------------------------------
 
-Google, NIST, and University of Michigan are working together to create a fully open test tile design using the `OpenFASoC generator approach <https://github.com/idea-fasoc/OpenFASOC>`_ and open source tooling. More details can be found at the following links;
