Switching Fabric Internal State Analyzer
Marek Michalski · 2024
This paper presents a GUI application for analyzing states of a switching fabric, it allows users to create a model of a multi-plane log2N switching fabric and analyze the behavior of different control algorithms. In this type of fabric, a desired path from a specific input to a specific output is determined by input and output numbers, and the algorithm must choose the appropriate plane. Connections sharing elements on the same path are in conflict and need to be realized in different planes. The relationship between connections and parts of their paths creates the internal state of the switching fabric, which can be analyzed using complex formulas and presented in various ways. The presented application simplifies the analysis of the fabric’s state and facilitates the development of more effective algorithms. Additionally, it includes additional tools such as FPGA core preparation, picture creation, and simulation capabilities.
