22
-- Purpose:    
23
--     This VHDL netlist is a verification model and uses simulation 
24
--     primitives which may not represent the true implementation of the 
25
--     device, however the netlist is functionally correct and should not 
26
--     be modified. This file cannot be synthesized and should only be used 
27
--     with supported simulation tools.
28
--

--     Development System Reference Guide, Chapter 23
