 * Description:
 *   This file is the Verilog behvarial model for the
 *       Block Memory Generator Core.
 *
 *****************************************************************************
 * Author: Xilinx
 *
 * History: Jan 11, 2006 Initial revision
 *          Jun 11, 2007 Added independent register stages for 
 *                       Port A and Port B (IP1_Jm/v2.5)
 *          Aug 28, 2007 Added mux pipeline stages feature (IP2_Jm/v2.6)
 *          Mar 13, 2008 Behavioral model optimizations
 *          April 07, 2009  : Added support for Spartan-6 and Virtex-6
 *                            features, including the following:
 *                            (i)   error injection, detection and/or correction
 *                            (ii) reset priority
 *                            (iii)  special reset behavior
