//// Generic Two-Port Synchronous RAM ////
//// ////
//// This file is part of memory library available from ////
//// http://www.opencores.org/cvsweb.shtml/generic_memories/ ////
//// ////
//// Description ////
//// This block is a wrapper with common two-port ////
//// synchronous memory interface for different ////
//// types of ASIC and FPGA RAMs. Beside universal memory ////
//// interface it also provides behavioral model of generic ////
//// two-port synchronous RAM. ////
//// It should be used in all OPENCORES designs that want to be ////
//// portable accross different target technologies and ////
//// independent of target memory. ////
//// ////
//// Supported ASIC RAMs are: ////
//// - Artisan Double-Port Sync RAM ////
//// - Avant! Two-Port Sync RAM (*) ////
//// - Virage 2-port Sync RAM ////
//// ////
//// Supported FPGA RAMs are: ////
//// - Xilinx Virtex RAMB16 ////
//// - Xilinx Virtex RAMB4 ////
//// - Altera LPM ////
//// ////
//// To Do: ////
//// - fix Avant! ////
//// - xilinx rams need external tri-state logic ////
//// - add additional RAMs (VS etc) ////
//// ////
