A way of shortening uvm_info filename to ONLY filename, not path/filename?

[aquarioz]

Hi all!

 

I've been trying to completely do without the full path of filename when reporting

 

for example

 

instead of

 

UVM_INFO /1/2/3/4/5/6/7/8/filename.sv (linenum) "Message"

 

I want completely remove or shorten the path

 

UVM_INFO /.../filename.sv (linenum)  "Message"

 

I've tried using

UVM_REPORT_DISABLE_FILE_LINE
UVM_REPORT_DISABLE_FILE

 

But it completely removes the filename and line num from the report.

 

I'm looking into the uvm source code and make my own modifications, but I don't want to mess around with the libraries since I share the installation directories.

 

Anybody has done this before?

 

Thank you!

You're much better off post-processing this in a PERL/AWK/SED script.

As per LRM the `__FILE__ expands to the filename as provided to the compiler. So in your compile script if you provide absolute path, you will get /abs/path/to/file, else ../relative_path:

 

For instance try the below code:

 

 

module m; 
  initial begin
    $display ("File: %0s Line: %0d",
              `__FILE__, `__LINE__);
  end
endmodule : m

 

qverilog  C:/tools/cygwin/home/Ajeetha/proj/svlog/FILE_macro_rel_path/FILE_macro_rel_path.sv

 

vs.

 

qverilog ../FILE_macro_rel_path.sv

 

See what happens

hi,

Personally, I dont see why you need the line/filename at all. if you are debugging somethign then bring it up in your gui and double click the message and it will take you to the `uvm_info line being called in your code.

Therefore, I compile with the disable FILE_LINE option.

 

However, some people like to see tonnes of messages appear in their logifles and for those they should review Brians' blog:

You can extend uvm report server and override compose message function.

Just choose what you want to print and then set this report server as your own report server.

As rustagi said, you can extend the uvm_report_server and have your own compose_message function. Here's what I do to have a filename without path and to customize other parts of the message too.

 

 

class custom_report_server extends uvm_report_server;

   virtual function string compose_message
     ( uvm_severity severity,
       string name,
       string id,
       string message,
       string filename,
       int line );

      // Declare function-internal vars
      string filename_nopath = "";
      uvm_severity_type severity_type = uvm_severity_type'( severity );    

      begin

         // Extract just the file name, remove the preceeding path
         foreach(filename[i])
           begin
              if (filename[i]=="/") filename_nopath = "";
              else                  filename_nopath = {filename_nopath,
                                                       filename[i]};
           end

         // number of initial spaces in the second line
         // = 8 + 1(space) + 1(@) + 7 + 2("ns") + 3(spaces) + 2(indentation) = 24
         return $psprintf( "%-8s @%7tns%3s\"%s\" >%s(%0d)\n%24s%s [%s]",             
                           severity_type.name(), $time/1000.00, " ",
                           name, filename_nopath, line, 
                           " ", message, id );   
      end
   endfunction: compose_message
endclass: custom_report_server

 

I would then put this in the base test. It is up to you where you want the new server to be effective: before build, before run, etc.

 

virtual function void build_phase(uvm_phase phase);
      // Set the custom report server to output the uvm_info messages in custom format
      custom_report_server my_server = new;      
      uvm_report_server::set_server( my_server );
      super.build_phase(phase);
      ......
endfunction

Based on other replies I have done the following:

class custom_report_server extends uvm_report_server;

   function new(string name="my_report_server");
      super.new();
   endfunction : new

   function string getShortFileName(string s);
      int offset = 0;
      int lastChar;
      string shortFileName;
      int slashPosition;
      
      lastChar = s.len()-1;
      for (int i = lastChar; i >= offset; i=i-1) begin
        if (s.getc(i) inside {"/", "\\"}) begin
          slashPosition = i;
          break;
        end
      end // for loop
          
       shortFileName = s.substr(slashPosition+1, lastChar);
       return shortFileName;
    endfunction

   virtual function string compose_message(
                                           uvm_severity severity,
                                           string name,
                                           string id,
                                           string message,
                                           string filename,
                                           int    line
                                           );
      uvm_severity_type sv;
      string                                      time_str;
      string                                      line_str;
      
      sv = uvm_severity_type'(severity);
      $swrite(time_str, "%0t", $realtime);
      
      case(1)
        (name == "" && filename == ""):
               return {sv.name(), " @ ", time_str, " [", id, "] ", message};
        (name != "" && filename == ""):
               return {sv.name(), " @ ", time_str, ": ", name, " [", id, "] ", message};
        (name == "" && filename != ""):
                 begin
                    $swrite(line_str, "%0d", line);
                    return {sv.name(), " ",getShortFileName(filename), "(", line_str, ")", " @ ", time_str, " [", id, "] ", message};
                 end
        (name != "" && filename != ""):
                 begin
                    $swrite(line_str, "%0d", line);
                    return {sv.name(), " ", getShortFileName(filename), "(", line_str, ")", " @ ", time_str, ": ", name, " [", id, "] ", message};
                 end
      endcase
   endfunction 
endclass: custom_report_server

and in the build_phase of the test

virtual function void build_phase(uvm_phase phase);
      // Set the custom report server to output the uvm_info messages in custom format
      custom_report_server my_server = new;      
      uvm_report_server::set_server( my_server );
      
      super.build_phase(phase);
...

endfunction

Based on other replies I have done the following:

class custom_report_server extends uvm_report_server;
...
endclass: custom_report_server

and in the build_phase of the test

virtual function void build_phase(uvm_phase phase);
...
endfunction

How do you inherit a abstract class (uvm_report_server) with a lot of 'pure virtual' methods overriding only a single 'compose_message' method?

[halfrater]

The issue is closed.
UVM 1.2 requires ‘uvm_default_report_server’ extending and ‘compose_report_message(..)’ method overriding.
