Cross-level hierarchical high-level synthesis

This paper presents a new approach to cross-level hierarchical high-level synthesis. A methodology is presented, that supports the efficient synthesis of hierarchical specified systems while preserving the hierarchical structure. After synthesis of each subsystem, the determined component schedule and the synthesized RT-structure are added to its algorithmic specification. This provides an automatic selection of optimized complex components. Furthermore, the component schedule enables the sharing of unused subcomponents across different hierarchical levels of the design
