Can anyone explain briefly on what does 'ovm_do_with actually does?

Question

I'm new to OVM and Saola. Can anyone explain what does

'ovm_do_with(a,{b=0}) actually does?

I only know about UVM, not OVM. I would imagine my answer is valid for OVM as well as UVM given the similarity, but you need to check this. — Matthew Taylor, Jan 03 '19 at 08:29

`uvm_do_with(req, CONSTRAINT)

is a macro. It expands to

req = tx_type::type_id::create("req");
start_item(req);
if( !req.randomize() with CONSTRAINT ) `uvm_error(...)
finish_item(req);

So

'ovm_do_with(a,{b=0})

expands to

a = tx_type::type_id::create("a");
start_item(a);
if( !a.randomize() with {b=0}) `uvm_error(...)
finish_item(a);
