Low Power Optimization Technique Suitable For Dual-logic Using AIG

The optimization of the power consumption of the integrated circuit is one of the hotspots in the current comprehensive design and optimization research.The current circuit design method is usually based on Boolean logic(Traditional),in fact,can also be Reed-Muller(RM)logic to achieve.The results show that for most logic functions,Reed-Muller logic has a good performance when it represents a part of the logic function,such as its speed,area,power consumption and so on.It also makes a logical optimization because of a single logical representation logic function Of the limitations,so part of the circuit with TB logic to achieve another part of the RM logic can be used to achieve better optimization.Therefore,the idea of power optimization based on dual logic of TB logic and RM logic has been paid attention to.And-Nonverter(AIG),as a logical function representation,is widely used by academics and industry to solve the optimization problem because of its simple structure and the one-to-one correspondence with the circuit.In this paper,based on the dual logic,combined with the structural characteristics of AIG,an effective AIG power estimation method is proposed.By detecting the low-power composite gate and combining the logical representation of the logic function,a logic function is proposed based on the sum-Dual-logical optimization and coverage method for And-Xor-Inverter graph(AXIG).In the process of covering,a method of covering the structure based on the structure is proposed.The main contents of the thesis include the following three parts:(1)AIG-based power estimation model is established: According to the characteristics of AIG representation of logic function and classification of AIG node characteristics,a switch is proposed to estimate the logic circuit based on AIG representation using hopping density and signal probability Active approach to achieve power consumption estimates based on AIG.The experimental results show that themethod can effectively realize the estimation of the circuit power and lay the foundation for the subsequent logic optimization.(2)The power optimization method based on dual logic is realized: the optimization method of logic function based on dual logic gate level representation is studied.On the basis of AIG,the XOR node is introduced,and a new data structure AXIG is proposed.The logic function is based on AXIG’s dual logic optimization and coverage method: RM logic and TB logic are realized by AXIG structure,Logical graph representation.Select the different XOR structure to cover,and cover the process of local logic structure again covered by three input gate structure,and ultimately to achieve the variable level and gate level of the two-level optimization method.The experimental results show that there is a certain advantage over the well-known ABC and the industry’s most advanced tool,Design Compile(DC).(3)AIG-based power optimization algorithm is proposed: the existing dual-logic coverage method is discussed.According to the power consumption estimation method,the structure of the linked list algorithm is studied.According to the switch activity and node information to measure whether the combination of coverage,and ultimately to achieve circuit power optimization technology.At present,the research on AIG is mainly focused on the comprehensive verification,the research on power consumption is still relatively immature,especially the theory and method of synthesis and optimization based on dual logic still need to carry out systematic research.This study focuses on the dual logic low power optimization algorithm based on AIG.Therefore,the study has theoretical and practical significance.
