Error: undefined identifier 'sev'

[geeta-yadav]

Hi
The compilation of the below test gives "undefined identifier 'sev' error while setting the severity:

import esdl;
import uvm;
import std.stdio;

class ac: uvm_object
{
@rand uint a;
string b;

mixin uvm_object_utils;

this(string name="")
{
super(name);
}
}

class b: uvm_comparer
{
this()
{
super();
sev=UVM_FATAL;
verbosity=UVM_NONE;
show_max=-1;
}
}

class catcher: uvm_report_catcher
{
uint cnt=0;
override action_e do_catch()
{
if(get_severity() == UVM_FATAL && get_id() == "MISCMP")
{
cnt++;
set_severity(UVM_INFO);
return THROW;
}

if(get_severity() == UVM_INFO && get_id() == "MISCMP")
  {
cnt++;
return THROW;
  }
return THROW;

}

}

class test_root: uvm_root
{
mixin uvm_component_utils;
override void initial()
{
ac mya,myb;
b policy;
catcher catch_;
catch_ = new catcher;
uvm_report_cb.add(null, catch_);
mya=new ac;
myb=new ac;
policy=new b;
mya.randomize();
mya.b="bang";
assert(mya.compare(myb, policy)==0);
// policy.verbosity=UVM_HIGH;
// policy.sev=UVM_INFO;
assert(mya.compare(myb, policy)==0); // changes and checks the ver ans sev
if(catch_.cnt != 3)
// `uvm_fatal("TEST",$sformatf("test failed, caught %0d messages",catch_.cnt))
{
uvm_report_server svr;
//svr = uvm_coreservice.get_report_server();
svr.summarize();
if (svr.get_severity_count(UVM_FATAL) +
svr.get_severity_count(UVM_ERROR) == 0)
writeln("** UVM TEST PASSED **\n");
else
writeln("!! UVM TEST FAILED !!\n");
}
}
}

class TestBench: RootEntity
{
uvm_root_entity!(test_root) tb;
}

void main(string[] argv) {
TestBench tb = new TestBench;
tb.multiCore(0, 0);
tb.elaborate("tb", argv);
tb.simulate();
}

Here is the error:

Error: undefined identifier 'sev', did you mean function 'sec'?
