Optimum Reconfiguration of Routing Interconnection Network in APSoC Fabrics

Abstract

This paper presents an automated algorithm for optimum configuration of routing interconnection network in Xilinx Zynq-7000 All programmable system-on-chip (APSoC) fabrics. A method to configure circuits with optimum routing resources is presented along with their performance parameters with and without the proposed algorithm. The proposed algorithm enables full control over routing resources for using different interconnection types in order to create routing-based circuit-undertest. The algorithm proposes the routing techniques through the 2-D array of switch matrices inside the interconnection network and automatically identifies the involved programmable interconnection points associated with a node. An experimental setup is proposed to measure the performance parameters such as slack time and power with and without the applied algorithm on the APSoC routing resources. The proposed setup requires no external equipment such as manufactured equipments or external instruments for performance measurement.
