| Abstract(in English) | The feature size of LSI is getting smaller year by year, increasing random variation between the elements. These days, the problem of the variation imposes too severe timing constrains to design circuit with enough timing margin. To overcome this problem, this paper proposes a clocking scheme with relaxed timing constrains. Our method separates logic paths into two kinds of paths, short path and critical path. The circuits will be allowed up to 1.5 clock cycle delay per stage, while existing method, two phase latch allows 1 clock cycle delay per stage. Timing margin produced by proposed method enables lower energy consumption and higher clock frequency. |
