介绍了LCD定标器的总体结构和工作原理,以及应用Xilinx公司的Virtex-Ⅱ系列FPGA进行LCD定标器芯片功能验证的方案.该方案使LCD定标器芯片和其他外部模块组成一个完整的工作系统,能对芯片的预期功能进行全面系统的验证,从而尽早地发现前期设计中存在的问题,以便及时修改RTL级代码来确保芯片的设计功能完全正确,达到预期设计目标.验证结果表明,提出的方案正确可行,良好地完成了验证定标器设计功能的任务.
The overall structure and working principle of LCD scaler and the scheme of verifying LCD scaler chip using Xilinx Virtex-Ⅱ series FPGA are introduced.The LCD scaner chip and other external modules form a complete Work system can verify the expected function of the chip in a comprehensive and systematic way so as to find out the problems in the early design as soon as possible in order to modify the RTL code in time to ensure that the design function of the chip is completely correct and achieve the expected design goal.The verification results show that, The proposed scheme is correct and feasible, and well fulfilled the task of verifying the design function of scaler.
