Abstract: Optical links and photonic integrated circuits require integration of photonic and electronic devices at chip, module, or board level. The complexity of such systems is motivating a need for system level CAD tools which can simulate electronic and photonic devices and circuits simultaneously and at multiple levels of abstraction. Furthermore integrating photonic devices into conventional electronic computer and communication systems needs to be justified in terms of cost, performance, and portability of existing computer software and hardware. Thus system level analysis of optoelectronic interconnect system is clearly necessary to ensure that an overall functional and performance requirements are met. The proposed approach for system level modeling is to integrate photonic device simulations into the established electronic design automation environment, particularly VHDL-based one. VHDL description of photonic devices will provide benefits such as portability of individual design, system level performance analysis before building a real system, and synthesis capability for a rapid- prototyping. This paper demonstrates the use of basic VHDL entities of various passive optical waveguide components and a special VHDL package (`Optical_Package') defining physical photonic parameters to verify the feasibility of this approach. It includes modeling and simulation of global signal distribution network on MCMs using optical interconnect and wavelength division (de)multiplexing-based optical link.!5
