FPGA的设计流程与关键问题以及解决方案分析

FPGA Design Flow and Key Issues and Solutions

FGPA的性能随着半导体技术的发展不断提高,并凭借高可靠性、方便的反复改写功能、灵活的用户现场编程功能等优点成为现代数字通信系统中的新宠。本文首先介绍了FPGA设计的一般设计流程,然后分析了设计中的关键问题产生的原因与影响,主要包括毛刺现象、时钟歪斜以及延迟效果不佳的现状三大点,最后对相应的问题提出解决方案。

FGPA performance is higher with the development of semiconductor technology. It is popular in the modem digital communication system with its high reliability, repeatedly rewritten function, and flexible field programming. The paper first describes the general design flow of FPGA design, and then analyzes the key issue in design, including burr phenomena, clock skew, and poorly-delay situation, finally gives the appropriate solution.
