Crosstalk from digital to analog circuits can be causative of operation fails in analog-digital mixed LSIs. This paper describes modeling techniques and simulation strategies of the substrate coupling noise. A macroscopic substrate noise model that expresses the noise as a function of logic state transition frequencies among digital blocks is proposed. A simulation system based on the model is ...

In this paper, synchronization and anti-synchronization of Bhalekar-Gejji chaotic system is proposed with application to secure communication. Further its analog circuit design and simulation is carried out using analog components. Proposed synchronization and anti-synchronization with application to secure communication is achieved using robust SMC. For communication, the information signal is...

We describe here a new strategy for computation and computer design optimized for simulation of complex (chaotic) dynamical systems. This strategy has the potential for performance many orders of magnitude higher than conventional digital computers. It combines three emerging technologies, collectively referred to as nanologic: (1) analog nanoelectronics; (2) adaptive analog arrays; and (3) top...

This paper presents a method for fast time-domain simulation of analog systems with nonlinear parameters. Specifically, the paper focuses on analog-to-digital converters (ADC). The method creates compiled-code simulators based on symbolic analysis. Code is optimized using loop invariant elimination and constant folding. Circuits are described as structural macromodels. Non-linear parameters are...

This paper proposes a methodology for extending SystemC to mixed signal systems, aimed at allowing the reuse of analog models and to the simulation of heterogeneous systems. To this end, a general method for modeling analog modules using wave quantities is suggested, and a new kind of port and channel suitable to let modules communicate via waves have been defined. These entities are plugged di...

The maximum power point tracking (MPPT) control in the Photovoltaic system is the key control technology, however present controller has the disadvantages of long development cycle, high cost and complex verification, and there are some disadvantages carrying out totally physical simulation or totally digital simulation of different control algorithms. This paper carried out design of hardware ...

During the past few years, a lot of work has been done on behavioral models and simulation tools. But a need for modeling strategy still remains. The VHDL-AMS language supports the description of analog electronic circuits using Ordinary Differential Algebraic Equations (ODAEs), in addition to its support for describing discrete-event systems. For VHDL-AMS to be useful to the analog design ...

We propose a digital-analog quantum simulation of generalized Dicke models with superconducting circuits, including Fermi- Bose condensates, biased and pulsed Dicke models, for all regimes of light-matter coupling. We encode these classes of problems in a set of superconducting qubits coupled with a bosonic mode implemented by a transmission line resonator. Via digital-analog techniques, an eff...

In this paper the attention is drawn on analog computer.For scientists attempting to prepare complex designs for simulation approach the analog computer assisted them. Extensive knowledge about the analog methods is required before preparing any analog design. The credit for the advent of analog computer goes to the invention of operational amplifier. Thus in 1950 the engineers and aircraft res...
