以一款视频图像定标器为研究对象,提出了一种适用于大规模数字集成电路的软件功能性验证平台,详细阐述了平台的结构、平台中测试向量的选择、生成以及测试结果的验证,采用自动向量生成与结果自检测方法,对定标器完成了1 200个测试类型的验证.描述了基于Xilinx开发板的定标器硬件验证平台,将经功能性验证后的硬件描述语言植入开发板的FPGA中,完成了硬件验证.为流片后的定标器芯片搭建了一个测试环境,试验结果完全符合预期设计.
As a kind of signal processing component, the scaler plays an important role in the flat panel display. Taking a video image scaler as researching target, a software verification platform suiting for VLSI chip design is introduced, whose testing vectors selection, testing vectors generation, results checking and architecture are explained thoroughly. Meanwhile,1 200 testing vectors are verified adopting patterns automating generation method. A hard-ware emulation platform based on Xilinx developing board is presented, and the verification is also finished with loading hardware description language into FPGA. A testing environ-ment for scaler has been implemented, and tape-out results shows that the scaler works well and meets the expectations.
