Abstract:The constraint-based approach to timing-driven placement requires delay budgeting to define the delay upper bounds for nets. While most of the previous delay-budgeting works have been focused on optimizing combinational circuits, the work in [9] introduces sequential budgeting, which combines budgeting and retiming to optimize sequential circuits better. However, the formulation in [9] does not consider flip-flop (FF) minimization, which is important in practical applications. Here, we propose a new sequential… Show more
