The requirement is the model itself as it is a low level test. The data can be extracted from the blocks. But I take your point. I think I can provide the data tables and other required inputs in the document included. It will take some time. If it was a control law with the plant model then I could specify the higher level model. In this context the requirement will be signal A1 shall be rate limited … and so on. Let me work on this.

Specifies great Testing methods

An excellent compilation!

You have shown the lack of focus on cost effective testing. That being the unit testing of algorithms should beat up the algorithms (assume all data values +-infinity to verify goodness. It is too expensive to find these faults in system testing. This presentation did a great service in presenting the objectives by phase and revealing a very weak design and development phase and really most of the objectives focused on verification (by test). You don't build a bridge then test it.. Its too late in the cycle. We need a far more rigorous in-development simulation and test program.. Kudos to developers that find their own weakness. Let's make sure the bridge is not just good but robust before building it.

Are there requirements available? How could we test without requirements?

Why dont you evaluate TPT the model based testing tool for Simulink and Stateflow models. http://www.piketec.com/products/tpt.php
