【摘要】 随着设计规模的不断增大,验证已成为芯片开发的瓶颈。根据有关的研究数据,目前在IC设计项目中,功能验证工作占据了整个设计流程的60%~80%的工作时间。验证一直而且将继续是设计中最困难和最有挑战性的课题之一。如何快速高效的实现功能验证平台,完成芯片的功能验证,成为当今IC设计验证领域的重要研究方向之一。本文的研究内容是基于一个实际的工程项目“基于OFDM无线广播系统接收芯片的研发”。该芯片已在CMOS0.13微米的工艺下成功流片。本论文主要设计和实现了一个验证平台。该验证平台应用于一款基于OFDM无线广播系统接收芯片而搭建的验证环境。该验证平台通过层次化的结构,实现了如下功能,包括数据载入,数据读取,波形产生,网表验证和软硬件协同等。通过该验证平台,很好地达到了制定的验证目标,为该接收芯片的成功流片提供了保障。论文首先对OFDM无线系统做了一个简单的介绍,然后介绍了IC验证的基础知识,接下来主要对基于OFDM无线接收芯片的设计做了一个概括性的介绍,最后是描述了整个无线接收芯片验证平台的设计以及实现及其验证结果。证明了该验证平台能够很好地支持芯片不同级别的验证,提高IC验证的效率,对以后的验证平台的搭建提供了很好的参考。更多还原

【Abstract】 As the increasing gate count of IC design, the verification process has become the bottleneck of the IC development. According to the survey, functional verification takes up 60%~80% of the total work hours. The verification process is still one of the most difficult and the most challenged tasks. How to complete functional verification platform in a given time, undertaking the verification process, are the main research area of the verification.The paper is based on a engineering project of“research and development of OFDM-based wireless demodulator chip”..This chip has been taped out successfully in CMOS 0.13 um technology. The verification platform is designed for the OFDM-based wireless broadcasting demodulator chip. With layered structure, the verification platform offers many functions, including data downloading, data reading, waveform generation, netlist verification and software-hardware co-verification. By this verification platform, we have finished the verification target, making assure the correctness of the demodulator chip.The paper summarizes the OFDM-based wireless communication system, and then introduces the basics of verification. Thirdly, the paper describes the OFDM-based demodulator architecture and finally the verification platform and the results. The paper has demonstrated that the verification platform supports different level of verification, promoting the efficiency and a good reference for building new verification platform.更多还原
