To Generate Seprate Log files for Easy Debugging in SOC verification

For easy debugging in SOC verification, generate separate log files for different IPs/Instances.

How to Generate separate Log files for different Functions/Layers/Instances/Files?

You can implement the below logic in your uvm environment to generate the separate Log files for each instances. Below I have written a piece of code to generate the separate Log files and you can refer the same.

For Example:

Without generating the Separate Log files,

///////////////////////////////////////////////////////////////////////////////////

// Test driver

class test_driver extends uvm_component;
`uvm_component_utils(test_driver) 

function new(string name,uvm_component parent);
super.new(name, parent);
endfunction 

task run();
uvm_report_info(get_name(), "Driver Info :: dump into the Log ",UVM_HIGH);
endtask

endclass

// Test monitor

class test_monitor extends uvm_component;
`uvm_component_utils(test_monitor) 

function new(string name,uvm_component parent);
super.new(name, parent);
endfunction 

task run();
uvm_report_info(get_name(), "Monitor Info :: dump into the Log ",UVM_HIGH);
endtask

endclass

// Test agent

class test_agent extends uvm_component;
test_driver log_drv;

test_monitor log_mon;

`uvm_component_utils(test_agent) 

function new(string name,uvm_component parent);
super.new(name, parent);
endfunction 

function void build();
super.build();
log_drv = test_driver::type_id::create("log_drv",this);

log_mon = test_driver::type_id::create("log_mon",this);

endfunction

endclass

///////////////////////////////////////////////////////////////////////////////////

With generating the Separate Log files,

///////////////////////////////////////////////////////////////////////////////////

// Test driver

class test_driver extends uvm_component;

string test;
`uvm_component_utils(test_driver) 

function new(string name,uvm_component parent);
super.new(name, parent);

test = “TEST”;
endfunction

task run();
uvm_report_info(test, "Driver Info :: dump into the Log ",UVM_HIGH);
endtask

endclass

// Test monitor

class test_monitor extends uvm_component;

string test;
`uvm_component_utils(test_monitor) 

function new(string name,uvm_component parent);
super.new(name, parent);

test = “TEST”;
endfunction

task run();
uvm_report_info(test, "Monitor Info :: dump into the Log ",UVM_HIGH);
endtask

endclass

// Test agent

class test_agent extends uvm_component;

integer log_ptr, log_ptr_id;
test_driver log_drv;

test_monitor log_mon;

`uvm_component_utils(test_agent) 

function new(string name,uvm_component parent);
super.new(name, parent);
endfunction

function void build();
super.build();
log_drv = test_driver::type_id::create("log_drv",this);

log_mon = test_driver::type_id::create("log_mon",this);

// set the uvm action for that ID

log_drv.set_report_id_action(“TEST”,UVM_LOG);

log_mon.set_report_id_action(“TEST”,UVM_LOG);

// open the file to dump

log_ptr = $fopen(“test.log”);

log_ptr_id = $fopen(“test_id.log”);

// to dump all log in the file

log_drv.set_report_default_file(log_ptr);

log_mon.set_report_default_file(log_ptr);

// to dump the particular ID log in the file

log_drv.set_report_id_file(TEST,log_ptr_id);

log_mon.set_report_id_file(TEST,log_ptr_id);

endfunction

endclass

With an above example you can have a display test case status without any signal/variable from the test environment.
