Expanding on interleaved multi-channel technology (IMT), SonicsGN® 3.0 includes layout optimization features for design flows based on physical synthesis as well as place and route tools. SoC designers can eliminate multi-channel DRAM access bottlenecks with IMT and reduce layout tool iterations with flexible user control of hierarchical RTL partitioning and re-timing stage insertion. Also included, flexible reordering buffer architecture enhances concurrency.
