这个错误的直接原因是 Verilog 不支持 Data_i[i*8-1:i*8-8] 这种语法。如果把向量的位选取写成 v...
不过还有很多其他问题，Verilog不是这么写的，你这是在当C语言在写。不要用repeat，这种语句不一定能综...
这个是用c语言写电路。那个for里面的i需要定义为genvar i；另外从你写的逻辑看，你是希望那个shift_reg不断的变化，但是你这么写的话。系统会认为是一个组合逻辑，所以会立刻计算出结果。你需要写成时续逻辑的电路，用always @（posedge clk）begin ...end ...
assign 不能放在if里，除非是generate if。如果用always，就不能用assign

晕，你要给count赋值就要把count定义成reg型的，不能定义成integer（整数型），改成reg[31:0]count试试。
is high forces q to remain at 0. This condition may or may not be correct depending on the actual flip flop. However, this is not the main problem with this model. Notice that when reset goes low, that set is still high. In a real flip flop this will cause the output to go to ...
