How many devices can be in a chain?

There is no limit to the chain architecture that ProVision can handle. Fanout considerations and chain cycle speed would enter into the decision as to how long a chain to implement. Refer to the DFT booklets for more information.  ProVision constructs your chain topology for you, automatically, so you don't need to input it and can be certain it's error-free.
