关于数字电路竞争-冒险现象的研究
摘要:随着科学技术的发展,数字电路在实际应用中起到了举足轻重的作用,例如PLD、FPGA等。本文介绍了竞争冒险的概念及产生的原因。就数字电路中出现的竞争冒险问题及解决办法,从理论和实践的角度对其进行了总结归纳,并举例分析了判别竞争冒险的方法和消除方法,提出人们在分析设计数字电路时要根据不同的电路情况采用不同的分析、判别和消除方法。
在数字系统设计和调试中,常产生传输延迟、竞争冒险、毛刺干扰等问题,这是传统仪器和消除方法无法解决的,在这种情况下出现了适用于软、硬件分析的新的测试、消除竞争与冒险现象的方法。准确的实现系统功能是每一个系统设计者追求的最终目标,面对越来越庞大的系统设计,设计者需要更加完善、准确地检测出竞争与冒险现象,这样才能保证设计的准确性。本论文在对国内外有关竞争与冒险现象的发展现状的研究上,还进一步对冒险现象新的检测、消除技术和基于FPGA的虚拟逻辑分析仪进行了分析和研究。

Research and Analysis on Race petition in Digital Circuit Design
Abstract:The digital circuits play a pivotal role in the practical application with the development of science and technology, For example, PLD, FPGA, etc. This paper proposes an experiment analysis on an enhanced algorithm of MVFDS. There are three part s in this paper, the first one is the introduction of features of the system, the second one is the process of experiment s which are conducted to verify the performance of the enhanced system. The third one is the conclusions and possible further improvements are discussed.
Many problems are caused during designing or debugging the digital system,which include the transmission delay,petition risk,the interference of burrs and so on. They can not be resolved by traditional instruments. In this situation,a new type of digital domain testing instrument named logic analyzer is made to analyze hardware and software,which can effectively solve these problems caused in the digital system. System evaluation is very important to a digital system designer. In order plete a precise system, digital engineer should give the system evaluation as early as possible. This thesis has researched the virtual logic analyzer based on FPGA to let more users use it,which bases on researching virtual instrument technology,FPGA technology and USB interface.
Key words:Race petition,Digital Circuit,Detection Technique,Logic Analyzer
