explores the design space by considering alternate implementations during high level synthesis. Also, thermal prooling of rtl designs is too time consuming and is not viable for large designs. For almost all the examples, MSS produces better results and executes much faster than the hierarchical rtl partitioning. For smaller designs, scheduling overhead can be reduced through approximate estimation procedures to evaluate the cost of level 1 segments form individual process costs. From the results, we infer that the hierarchical behavioral partitioning is both a suitable and a viable approach to multicomponent synthesis and hierarchical packaging.
