HDL Simulation and mathematical modelling integration

This paper presents a new approach in domain of high level digital circuits simulation and modelling that benefits from high level mathematical environment delivered by MATLAB. It allows to integrate design process and directly verify obtained results with mathematical formulas or complex operations that are not available in standard HDL languages. A part of HDL code can be placedfor verification purposes inside the advanced mathematical model or can execute complex calculation. Paper presents problems that are introduced by hybrid simulation and modelling environment concerning data representation, simulation process and optimal performance.
