WebClock gating is a very common technique to save power by stopping the clock to a module when the module is not operating. As discussed in Clock switching and clock gating checks, there are two kinds of clock gating checks at combinational gates. WebThe clock gating signal should only toggle when the latch is closed, otherwise there is a chance for glitches and metastability issues. For an active high latch, the gating signal … Webclock muxing Clock gating checks Today’s designs have many functional as well as test modes. A number of clocks propagate to different parts of design in different modes. And a number of control signals are there which control these clocks. These signals are behind switching on and off the design. coffee machine emoji

WebFollowing strategies can be useful in reducing the magnitude of setup violation and bringing it closer towards a positive value: 1. Increase the drive strength of data-path logic gates: A cell with better drive strength can charge the load capacitance quickly, resulting in lesser propagation delay. WebFlop control points – In order to let propagate both ‘0’ and ‘1’ through control points, flops need to be inserted. In case of ‘0’ and ‘1’ control points, the control input of mux can be tied to ‘0’ or ‘1’. Hence, area overhead is only a mux. On the other hand, flop control points come with an overhead of an extra flop.
