Interoperability and quality of new EDA tools for sequential logic synthesis

One of the main problems in design of modem microelectronic systems is achieving consistent high quality results along the entire EDA tool chain. Using the sequential logic synthesis tools for a case study, this paper shows how important is the consistent tool collaboration for the quality of the final result. In the paper, a new uniform and consistent information-driven logic synthesis approach is proposed and compared to some other logic synthesis flows, including the traditional flow involving JEDI and SIS. The experimental research demonstrates that the quality of the new information-driven logic synthesis tools and the harmony of the new uniform approach results in much better circuits than the circuits from all other flows. The information-based synthesis flow produced circuits that are on average 25% smaller and 30% faster than the circuits from traditional flow.
