Creating Explicit Communication in SoC Models Using Interactive Re-Coding

Abstract

Communication exploration has become a critical step during SoC design. Researchers in the CAD community have proposed fast and efficient techniques for comprehensive design space exploration to expedite this critical design step. Although these advances have been helpful in reducing the design time significantly, the overall design time of the system is still a bottleneck. All these techniques assume the availability of an initial SoC input model with explicit communication, whose quality significantly impacts the effectiveness of the communication exploration techniques. Today, these initial models need to be manually written by engineers, which is tedious, error-prone and time consuming. In fact, our studies on industrial-size examples have shown that about 50% of the communication exploration time is spent on coding and re-coding of the initial specification model. In this paper, we propose an efficient interactive approach to explicit communication creation by automating some of the common coding tasks in specification models for communication exploration. Our results show significant savings in designer time.
