9.1 ON-CHIP COMMUNICATION ARCHITECTURE REFINEMENT

Early work on interface-based design [1, 16] motivated the need for orthogonaliz-

ing communication from behavior to handle increasing SoC complexity, and using

an iterative refi nement methodology to create detailed implementation models

from high level abstract models, for the on-chip communication architecture.

While higher-level abstractions provide better simulation performance, it comes

at the cost of accuracy and visibility into fi ner details, which can be realized

only with lower abstraction levels. Much of the early research in this area [2–4]

focused on obtaining signal-accur ...
