Hierarchical Methodology Approach to SOC Design: A Comprehensive Look
Abstract: The design scale of a chip has increased many folds in the last few years and shows a continuous exponential trend. This is made possible by the reduction in transistor size and an evolving process technology. As a result, it is possible to move to SoC technology (System on Chip-A single die consisting of multiple subsystems) rather than a traditional ASIC. This has obviously resulted in an increase in the …
