Sequential clock gating provides significant power savings because it not only switches off the clock going to registers but also the datapath logic in the fanout of gated registers. However, RTL synthesis tools are not capable of identifying sequential clock gating opportunities. Fortunately, recently ...
high-performance Building Block IP. The DesignWare Library Datapath and Building Block IP are tightly integrated into Design Compiler (DC) and are part of the DC installation. The Library has a number of arithmetic, combinational, sequential, and floating point components, and many other blocks su...
