--             

-- Purpose:    

--     This VHDL netlist is a verification model and uses simulation 

--     primitives which may not represent the true implementation of the 

--     device, however the netlist is functionally correct and should not 

--     be modified. This file cannot be synthesized and should only be used 

--     with supported simulation tools.

--

--     Development System Reference Guide, Chapter 23

--     Synthesis and Simulation Design Guide, Chapter 6
