Design And Implementation Of Test Bench Of Ofdm-based Wireless Demodulator

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.
