File parsing

UVM
1

Hi,
I have a txt file in this form:
Module:m1 path:pi1
Module:m2 path:po2
Module:m3 path:po3
Module:m4 path:pi4
and so on

I want to parse it and take only the part after “path” and only the ones with that contain po and then add a string to it, so each line should look like:
po2.addr
po3.addr

I’m reading the txt file using

while(!feof(file.txt))
fscanf(file,“%s”, line)

In reply to karin hallon:

Something like the code below will enable you to access the part after “path”
when I simulate this code I get the following output:

entry1=Module:m1

entry2=path:p1

module_name=m1

path_name=p1

Hope that helps…

function string split_using_delimiter_fn(string str,string del);

  string result;

  for (int i = 0; i < str.len(); i=i+1) begin
    if (str.getc(i) == del) begin
	   result = str.substr(i+1,str.len()-1);
       return result;
	end 
  end
endfunction
	
	
module file_parser();
initial begin
  string entry1, entry2;
  string hdr1, module_name, hdr2, path_name;
int fd;
fd= $fopen("Input.txt","r");
  $fscanf(fd,"%0s %0s", entry1, entry2);
  $display("entry1=%0s",entry1);
  $display("entry2=%0s",entry2);
  
  module_name = split_using_delimiter_fn(entry1, ":");
  $display("module_name=%0s", module_name);
  path_name = split_using_delimiter_fn(entry2, ":");
  $display("path_name=%0s", path_name);
