In reply to dv_engr:

Where is my_sequencer defined? It looks like you are trying to use a parameter (my_trans) with a non-parameterized class (my_sequencer).

You should always use the default uvm_sequencer, so you should have:


  uvm_sequencer#(my_trans) sequencer;

and create it in the build phase with:


  sequencer = uvm_sequencer#(my_trans)::type_id::create("sequencer", this);
