In a digital circuit system, IR drop effect can be alleviated by reducing the peak current of the system. Clock skew scheduling is a popular technique for peak current reduction. In this paper, we propose two algorithms that apply a Multiple Threshold CMOS (MTCMOS) technique rather than clock skew scheduling to do peak current reduction. MTCMOS techniques are feasible to reduce peak current because...
Clock skew scheduling for peak current reduction is a conventional technique for solving IR-drop problem in physical design stage. In this paper, we propose two kinds of long delay flip-flops and a heuristic algorithm that is used to resynthesized flip-flops of a circuit. Because the switching times of flip-flops in the resynthesized circuit are staggered, the IR drop effect can be reduced. Unlike...
