Formally Correct Control Elemental Blocks

DO331 talks about element blocks. I have put a set of element blocks that I had developed in 2005. These blocks are now validated formally using Simulink Design Verifier. This is added to help understand the concepts and to demonstrate a way in which you can formally test your company specific blocks. This will, I believe, help the students to understand the concept pf safety critical blocks. I will be very happy if students could take some of these blocks and extent it to certain components in their projects.
