A VHDL-based HW/SW cosimulation of communication systems

Abstract In this paper, we introduce homogeneous cosimulation method, which is suitable for modeling and simulation of systems comprising hardware (HW) and software (SW) components. In this method, a hardware description language with embedded programming capabilities (like VHDL) is used to model both HW/SW parts at any desired level of abstraction. Because of platform homogeneity, no sophisticated coordinator interface between HW/SW models is required, and also the final system can be constructed from these models easily and rapidly using CAD tools. We have applied this method to ISDN user–network interface and discussed about its benefits and drawbacks.
