// Purpose:    
//     This verilog 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.
