基于ModelSim的数字滤波器设计与验证教学实践OA

This paper expounds a teaching practice scheme for the design and verification of digital filters based on the ModelSim software,covering key steps including filter digitization,Verilog pipelined design and verification with the Testbench.The effectiveness of the designed algorithm is verified according to the filtering effect of the designed filter on signal sources with different frequencies.By designing a first-order RC low-pass digital filter,applying test stimulus signals of different frequencies to it,and analyzing its filtering output effect,the effectiveness of the designed algorithm is verified.This teaching practice helps students gain a deep understanding of the design flow of digital integrated circuits and improve their engineering practical capabilities as well as the spirit of innovative exploration.
