Overlap and frontiers between behavioral and RTL synthesis

Scheduling, resource allocation and binding are traditionally classified as behavioral synthesis tasks. However, advanced RTL synthesis tools could execute the last two tasks. Hence, an overlap of functionality will be found in most new design environments. In this paper, we present a new design flow with flexible frontiers between behavioral and RTL synthesis tools. Our results show that it is worth to give the designer this extended degree of freedom, since the best solution is not always the result of a specific design flow
