저전력 설계는 CMOS 기술이 나노미터 시대에 진입하면서 중요한 요구 사항이 되었습니다. 다중 공급 전압(MSV)은 성능을 유지하면서 동적 및 정적 전력 감소를 위한 널리 사용되고 효과적인 방법입니다. 레벨 시프터는 면적 및 ILO(상호 연결 길이 오버헤드)를 유발할 수 있으므로 평면도 작성 및 평면도 작성 후 단계에서 모두 고려해야 합니다. 본 논문에서는 전압 및 레벨 시프터 할당 문제를 해결하기 위해 VLSAF라는 2단계 알고리즘 프레임워크를 제안합니다. 평면도 단계에서는 볼록 비용 네트워크 흐름 알고리즘을 사용하여 전압을 할당하고 최소 비용 흐름 알고리즘을 사용하여 레벨 시프터 할당을 처리합니다. 평면 계획 이후 단계에서는 공백을 재분배하고 레벨 시프터의 위치와 모양을 계산하기 위해 휴리스틱 방법을 채택합니다. 실험 결과는 VLSAF가 효과적이라는 것을 보여줍니다.

Abstract: Low Power Design has become a significant requirement when the CMOS technology entered the nanometer era. Multiple-Supply Voltage (MSV) is a popular and effective method for both dynamic and static power reduction while maintaining performance. Level shifters may cause area and Interconnect Length Overhead (ILO), and should be considered at both floorplanning and post-floorplanning stages. In this paper, we propose a two phases algorithm framework, called VLSAF, to solve voltage and level shifter assignment problem. At floorplanning phase, we use a convex cost network flow algorithm to assign voltage and a minimum cost flow algorithm to handle level-shifter assignment. At post-floorplanning phase, a heuristic method is adopted to redistribute white spaces and calculate the positions and shapes of level shifters. The experimental results show VLSAF is effective.

AB - Low Power Design has become a significant requirement when the CMOS technology entered the nanometer era. Multiple-Supply Voltage (MSV) is a popular and effective method for both dynamic and static power reduction while maintaining performance. Level shifters may cause area and Interconnect Length Overhead (ILO), and should be considered at both floorplanning and post-floorplanning stages. In this paper, we propose a two phases algorithm framework, called VLSAF, to solve voltage and level shifter assignment problem. At floorplanning phase, we use a convex cost network flow algorithm to assign voltage and a minimum cost flow algorithm to handle level-shifter assignment. At post-floorplanning phase, a heuristic method is adopted to redistribute white spaces and calculate the positions and shapes of level shifters. The experimental results show VLSAF is effective.
