基于CPLD/FPGA的数字电路设计方法变革必要性研究

大规模可编程逻辑器件的应用已经为数字系统的设计带来了极大的灵活性。标准化逻辑设计语言的引入,极大地改变了传统的数字系统设计方法、设计过程和设计观念。作为大学的技术基础教学环节,应做出相应的调整。分别通过组合逻辑和时序逻辑设计实例比较了传统设计方法存在的问题和现代逻辑设计方法的优势。通过对比可以看到,现代逻辑设计技术取代传统的数字系统设计方法而成为数字电路设计的主流,是电子技术发展的必然趋势。

Research on the necessity of change in digital circuit design method based on CPLD/FPGA

Application of large-scale programmable logic device has brought great flexibility to digital system design. The in-troduction of standard logic design language has greatly changed the design method,design process and design concepts of tradi-tional digital system. As a technical foundation teaching link in the university,it should be adjusted accordingly. The problems of the traditional design approach and advantages of modern logic design methods are compared through the combinational logic and sequential logic design examples. By contrast,the modern logic design techniques has replaced the traditional method of digi-tal system design and become the mainstream of the digital circuit design,which is the inevitable trend of development of elec-tronic technology.
