In the layout of the cyusb3014 chipset footprint seems that have a dissipator, is it necessary? 

Thanks in advance!

There is no heatsink for FX3 on the DVK board. How did you infer there is a heatsink from the footprint? is the hardware design guidelines. Use this and you should be fine.

In the following image you can see the footprint, arround de chipset pins there are a shape in Place_Bound_Top layer

and various mechanical pins, I have assumed that it seem a dissipator. 

What's the use of this shapes and holes? May be for EMI or ESD purposes? I can skip this clearance?
