default_clock_driver and xlpersistentdff. What are they used for?

Hello all,

 

Everytime I convert a System Generator circuit into HDL code, it creates 3 modules.

1- The module of the circuit.

2- A module called default_clock_driver

3- A module called xlpersistentdff

 

What are this two modules used for? It seems they have no functionality.

Sysgen manages the clock implicitly, it does not have the DCM/PLLs, in order to get different blocks running at different rate, it uses clock enable, default_clock_driver is the module generated by the tools which controls the rate of all the blocks in the design by using the clock enable.
