What is the meaning of numbers in UVM_INFO?

Question

The following message is from a transcript file created by running QuestaSim to simulate dut. What does the number 39 mean?

UVM_INFO /home/Icer/nocc/noc-router/vips/hermes_pkg/src/hermes_agent.sv(39)
        @ 0: uvm_test_top.env.agent_master_0 [agent] PORT number: 0

In order to better understand the mechanism of the UVM sequence, I try to figure it out by understanding the log file.

Answer 1

The number in the parentheses immediately after the file name, 39, indicates the line number in the hermes_agent.sv source code file where the log message originates. On line 39 of that file, you likely have a `uvm_info() call.

In the UVM library source code, `uvm_info() has this line:

   uvm_report_info (ID, MSG, VERBOSITY, `uvm_file, `uvm_line); \

where

`define uvm_line `__LINE__

Refer to IEEE Std 1800-2017, section 22.13 `__FILE__ and `__LINE__ :

`__LINE__ expands to the current input line number, 
in the form of a simple decimal number.
