Recognizing and Simulating Sketched Logic Circuits
نویسندگان
چکیده
This paper presents a system for recognizing sketched logic circuits in real-time and graphically simulating them afterwords. It has been developed for use in university and school education. Circuit gate symbols are recognized using a multilayer perceptron network. The simulation is fully controlled by hand-drawings, and the inputs to circuits can be defined by writing numbers next to them. In addition to the simulation of simple circuits, recursive circuits can also be handled by the system. Furthermore, clock elements can be added for the purpose of synchronization, and circuits can be stored to be reused as sub-circuits, allowing the user to build arbitrary complex configurations. The usability of the system has been tested in a small video-taped laboratory test.

Efficient Genetic Based Methods for Optimizing the Reversible and Quantum Logic Circuits
Various synthesis methods have been proposed in the literature for reversible and quantum logic circuits. However, there are few algorithms to optimize an existing circuit with multiple constraints simultaneously. In this paper, some heuristics in genetic algorithms (GA) to optimize a given circuit in terms of quantum cost, number of gates, location of garbage outputs, and delay, are proposed. ...
متن کاملA Minimal-Cost Inherent-Feedback Approach for Low-Power MRF-Based Logic Gates
The Markov random field (MRF) theory has been accepted as a highly effective framework for designing noise-tolerant nanometer digital VLSI circuits. In MRF-based design, proper feedback lines are used to control noise and keep the circuits in their valid states. However, this methodology has encountered two major problems that have limited the application of highly noise immune MRF-based circui...

متن کاملA Fast and Self-Repairing Genetic Programming Designer for Logic Circuits
Usually, important parameters in the design and implementation of combinational logic circuits are the number of gates, transistors, and the levels used in the design of the circuit. In this regard, various evolutionary paradigms with different competency have recently been introduced. However, while being advantageous, evolutionary paradigms also have some limitations including: a) lack of con...
متن کاملA Logic for Quantum Computation and Information
The present paper formulates a language for quantum computation and information. This language makes it possible to write equivalent formulas for all combinational quantum circuits including the Grover search circuit. It is recursively axiomatised. The axiomatization is complete and decidable. Algorithms for uniform translation of quantum circuits into formulas in the language are sketched and ...
