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
. What I am trying to do in essence is(for 3 numbers): always@(posedge clk) out=in+in+in; I am getting the error: "j is not a constant". I am sure there is a method to do this, am I trying to do this in a wrong way? My full code is: ...
