Transaction-Based Online Debug for NoC-Based Multiprocessor SoCs

Abstract

Abstract-As complexity and size of Systems-on-Chip (SoC) grow, debugging becomes a bottleneck for designing IC products. In this paper, we present an approach for online debug of NoCbased multiprocessor SoCs. Our approach utilizes monitors and filters implemented in hardware. Monitors and filters observe and filter transactions at run-time. They are connected to a Debug Unit (DU). Transaction-based programmable Finite State Machines (FSMs) in the DU check assertions online to validate the correct relation of transactions at run-time. The experimental results show efficiency and performance of our approach.
