Simultaneous Operation Scheduling and Operation Delay Selection to Minimize Cycle-by-Cycle Power Differential

The cycle-by-cycle power differential determines the noise introduced due to inductive ground bounce. However, very few attentions are paid to minimize the cycle-by-cycle power differential in high-level synthesis stage. In this paper, we investigate the simultaneous application of operation scheduling and operation delay selection for minimizing the cycle-by-cycle power differential. An integer linear programming (ILP) approach is proposed to formally formulate this problem. Benchmark data consistently show that our approach can minimize the cycle-by-cycle power differential within an acceptable run time. Compared with previous work, the relative improvement of our approach achieves 44.8%.
