A unified HW/SW system-level simulation framework for next generation wireless system

Abstract

Recently, wireless technology experiences a fast growth to meet user demand and push toward the boundary limit of system performance. The simulation and verification framework play important role for accelerating investigation of technology proof of concept, field-trial, and large-scale commercial prototyping. In this paper, we present system-level simulation of heterogeneous model and unified HW/SW framework, particularly for next generation wireless system. The proposed framework includes a unified HW/SW co-evaluation methodology, the flexible HW/SW architecture, and fast HW/SW co-evaluation. The co-evaluation is carried out by employing hardware-in-the loop scheme that covers various abstraction level of simulation, from algorithm-level into physical-level simulation, with respect to system level simulation. The proposed co-verification framework allows a comprehensive system evaluation for a wireless system, involving various system parameters, hardware impairments, different channel conditions and cross-layer evaluations with fast run-time evaluations. Additionally, we also show an application example of multi-user wireless communication system and its experimental evaluations.
