System and chip synthesis must evaluate candidate Register-Transfer (RT) architectures with respect to finished physical designs. Current RT level cost measures, however, are highly simplified and do not reflect the real physical disign. Complete physical design, on the other hand, is quite costly, and infeasible to be iterated many times. In order to establish a more realistic assessment of layout effects, we propose a new layout model which efficiently accounts for the effects of wiring and floorplanning on the area and performance of RT level designs, before the physical design process. Benchmarking has shown that our model is quite accurate.
