Modeling and Simulation of High Speed Digital Circuits and Interconnects

چکیده
Careful design, modeling and simulation of modern high speed circuits is a vital issue in today’s electronic industry. High speed data transfer, and high processing power are accomplished if the circuit of the high speed net was modeled and designed properly. We present the main modeling techniques for both high speed circuits and interconnects used in industry nowadays. A modeling example of a 100MHz DDR (Dual Data Rate) memory net is considered. SPICE and IBIS models were used for the drivers/receivers (SSTL), while the interconnects and PCB trace models were generated using a 2D field solver (Maxwell). The net was simulated, and the advantages and disadvantages of various modeling techniques were discussed.

This paper introduces a new design of penternary inverter gate based on graphene nanoribbon field effect transistor (GNRFET). The penternary logic is one of Multiple-valued logic (MVL) circuits which are the best substitute for binary logic because of its low power-delay product (PDP) resulting from reduced complexity of interconnects and chip area. GNRFET is preferred over Si-MOSFET for circui...
