实验2：流水灯 实验步骤 1. 启动QuartusII建立一个空白工程,保存为led_water.qpf. 2. 将test2ledwater.v、int_div.v、setup.tcl拷入工程目录。 3. 将ledwater.v、int_div.v加入工程并进行综合编译，察看编译报告。从ledwater.v、int_div.v创建符号文件led.bsf、int_div.bsf。 (Experiment 2: water lamp experiment 1. Start to create a blank project QuartusII, save for led_water.qpf 2. The test2 ledwater.v, int_div.v, setup.tcl copy into the project directory. 3. The ledwater.v, int_div.v join the project and compile a comprehensive view of compiling the report. From ledwater.v, int_div.v create a symbol file led.bsf, int_div.bsf.)
