Research And Implementation Of Simulation And Visualization Method Of Reversible Logic Circuits

As the integrated circuit scale is becoming bigger and density is becoming higher,it’s energy consumption problem is becoming more and more difficult, to reduce integrated circuit’s energy consumption is crucial.The key to reduce energy consumption is turn irreversible operations to reversible operations.As quantum logic gates are all reversible,the operations of reversible logic circuits which is designed and connected by quantum logic gates are all reversible,hence it does not lose input information,does not have heat dissipation,it solve chip’s information energy consumption fundamentally.Therefore reversible circuit is regarded as the only way to reduce integrated circuit’s energy consumption,extend correlation technique and develop the industry.As reversible circuit is still quite young,the research domestic and overseas is also in a preliminary phase, existing design method generally cannot balance circuit scale and optimization degree,the relative theories systems and technology platform is inadequate, or even non-existent.The research and implementation of reversible logic circuit’s simulation and visualization method mainly study the way turn logical expression to logic circuit diagrams,simulation waveform,reversible truth table.Those work will be very helpful for analyze or comprehend structure and logic function of reversible logic circuit,therefore it’s very meaningful or even extremely important for research and application of reversible logic circuits’ synthesis and optimization.This thesis mianly research on simulation and visualization of reversible circuit,mainly targets to logic circuit(given as the form of logical expression), at first analyze and transform it to get and draw its logic circuit diagram,then simulate the circuit through software which is based on circuit model and logical operation,determine the corresponding relation of interior logical calculating process and external in-out,show as the form of logic circuit diagram,waveform,truth table and other forms,intellectualized judge the reversibility of truth table which is generated orgiven,turn irreversible truth table to reversible truth table.This article focus on study,programming and experimental tests of relevant method and algorithm.The study and results of this article is helpful for the study of reversible logic synthesis etc.
