An empirical study on the effects of physical design in high-level synthesis

The authors explore the combined effect of style and aspect ratio variations on the area and delay of RT level components, which in turn affects high-level synthesis decisions. Their results indicate that point models, where a component´s area and delay are assumed to be constant for a given style, are inadequate for use in the synthesis process due to the large variations in the area and delay that occur when component aspect ratios are varied. They believe that the results have some deep implications with respect to the flow of the design tasks during high level synthesis
