Abstract:
Many applications that are DSP based or certain communication application require mathematical modelling for their easy understanding and analysis. Due to its complexity Pure HDL is unable to simulate. Also it terms to be costly and time consuming process. We propose an alternative approach based on mixed HDL-Simulink platform. Basic properties of the simulation process in Simulink are addressed. The problems of data and signal transfers, driving samples, synchronization and entire communication between HDL and Simulink are described in details. A methodology for implementing DSP based or communication applications on a field programmable gate arrays (FPGA) using Xilinx System Generator (XSG) for Matlab. Implementation of examples related to DSP and Communication based designs are presented.
