function void build();
ovm_factory f;
f=ovm_factory::get();
f.set_type_override_by_name("sequence_1","sequence_2");
endfunction //coded in Test Build functionI have tried overriding the above sequence1 by sequence2. But once the test runs it not happening. Still my sequence1 is being used by the subsequences. please give me a solution. I am new to writing test cases
-------------------------------------------------------------------------------
// sequence_1 is coded in a separate package,eg ., apb_seq_pkg as follows,
class sequence_1 extends apb_seq_pkg::apb_base_seq;
`ovm_sequence_utils(sequence_1, ovm_sequencer)
function new();
super.new();
endfunction
task body();
write_reg(data,status,reg_name,dev_name);
endtask
function void print_cfg();
endfunction
endclass
-----------------------------------------------------------------------------
// sequence_2 is coded below the test itself,
function void build(); //part of test build function alone
ovm_factory f;
f=ovm_factory::get();
f.set_type_override_by_name("sequence_1","sequence_2");
endfunction
class sequence_2 extends apb_seq_pkg::sequence_1;
`ovm_sequence_utils(sequence_2, ovm_sequencer)
function new();
super.new();
endfunction
task body();
// write_reg(data,status,reg_name,dev_name); //basically i need to disable this write so i am trying to do sequence override. The apb_seq_pkg(sequence_1) is a softlink so i need to do overrride from test only to disable the write. The sequence is called in subsequence through the test.
endtask
function void print_cfg();
endfunction
endclass
------------------------------------------------------------------------
This is not working for me. The register write is happening anyway. please help me on this. I am new to ovm.
