Technology scaling into subnanometer range will create process variations that have impact on the overall manufacturing yield and quality. Smaller feature sizes permit to pack more functionality into a single chip. Increasing variability, complexity and communication bandwidth requirements will make the System-on-Chip designer’s goal, to design a fault-free system, a very difficult task. Shift from traditional bus-based systems to networked systems solves several design problems but requires more focus on communication modelling. In this work we propose a system-level approach for communication modelling and synthesis. It makes possible to calculate precise communication delays that can be taken into account during application scheduling to avoid network congestions. We present a possible application of the proposed framework for scheduling fault-tolerant applications on non-reliable network.
