Thread: How to make a SystemVerilog Class to read a text vector

How to make a SystemVerilog Class to read a text vector
and how to sync it with the global clock? read every byte per cycle

I have tried to write one but it seems not work... can anyone give me a hint on that?

Code:

class   #(parameter File_Name  = "input_vector.txt",
            parameter Data_Width = 12) SIM_MEM;
    
    reg     [Data_Width-1:0]    Data;
    
    function new(input File_P);
    integer     File_P;
    begin
      File_P = $fopen(File_Name, "r");
      if(!File_P) begin
        $display("File %s open failded, no such file!", File_Name);
        $finish(2);
        end
      else begin
        if(!$feof(File_P)) begin            
            $fscanf(File_P, "%h", Data);
            return Data;
            end
        else begin                            
            $display("%s reaches file's end!", File_Name);  
            $fclose(File_P);                
            $finish(2);
        end
    end
  endclass

the input vector format:
000
123
AAB
012
0EF
23F
876
...
...
...

any hint?

I think PERL or Python are more suited for text handling.

I do not use sv to process my text file; I just use it read the vector from the file and feed the vector to the testbenches or DUT.
The reason why I need a sv class here is the class can be easily reused and called.
