Exploiting area/delay tradeoffs in high-level synthesis

This paper proposes an enhanced scheduling approach for high-level synthesis, which relies on a multi-cycle behavioral timing analysis step that is performed before and during scheduling. The goal of this analysis is to accurately evaluate the criticality of operations and determine the most suitable candidate resources to implement them. The efficiency of the approach is confirmed by testing it on industrial examples, where it achieves, on average, 9% area savings after logic synthesis.
