dc.description.abstract반도체 공정의 발달로 집적도가 증가하고 문턱전압이 감소하면서, 반도체 집적회로 소모 전력에서 누설전류(leakage current)의 비중이 점차 증가하고 있다. 대기 상태에서 CMOS 조합 회로(combinational circuit)는 입력 값에 따라 누설전류가 크게 달라진다. 본 연구에서는 누설전류로 인한 소모전력을 줄이기 위해 대기 상태 (standby state) 회로의 입력 신호를 제어하며, 작은 누설전류를 갖는 입력 신호를 찾기 위한 새로운 효율적인 알고리즘을 개발하였다. 이 방법을 벤치마크 예제에 실험적으로 적용하여 누설전류 평균값에 비해 15.7%, simulated evolution 방법에 비해 6.7% 누설전류를 줄일 수 있음을 보였다. 또한 순차 회로에서도 idle 입력을 이용하여 누설전류 평균값에 비해 6.8%, simulated evolution 방법에 비해 3.2% 누설전류를 줄일 수 있었다.-
dc.description.abstractDue to increased integration density and reduced threshold voltages, leakage current reduction becomes important in the semiconductor IC design for low power consumption. In a combinational logic circuit, the leakage current in the standby state depends on the values of the input. In this research, we developed a new input vector control method to minimize the leakage power. A new efficient algorithm is developed to find the minimal leakage vector. It can reduce the leakage current by 15.7% from the average leakage current and by 6.7% from the results of simulated evolution method during standby or idle states for a set of benchmark circuits. The minimal leakage input vector, with idle input signal, can also reduce the leakage current by 6.8% from the average leakage current and by 3.2% from the results of simulated evolution method for sequential circuits.-
