This paper presents a co-design tool developed at the Institute for Software Integrated Systems, Vanderbilt University. It focuses on modern FPGAs with embedded processors, exploring design space exploration, system synthesis, and model-based design methods. The system features components like OPB and PLB bus architectures and supports high-bandwidth hardware-software communication. By allowing efficient interface generation and applying system constraints, the tool accommodates a vast design space and facilitates the evaluation and verification of designs using MATLAB and Xilinx Virtex-II Pro resources.
