Parameterized class error

UVM
3

Thanks for the response, Dave. How about the 2nd syntax, does that work?

I am trying to make the following implementation.


`uvm_analysis_imp_decl(_bypass);
class base_sequencer #(type REQ = base_seq_item,
                       type BYPASS = base_seq_item,
                       type SUBSCRIBER)
extends uvm_sequencer #(REQ);

    `uvm_component_param_utils(base_sequencer#(REQ, LOOPBACK_REQ, SUBSCRIBER));

     uvm_analysis_imp_bypass #(BYPASS, SUBSCRIBER) bypass_port;

     //! Subscriber function for bypass transaction
     function void write_bypass (BYPASS trans);
          //Logic to receive and store the trans
     endfunction : write_bypass

I have sequences that are reactive, i.e they need to get driven based on transactions seen from other agents. I am using the other agent’s sequencer as the subscriber. And the other agent’s transaction type is ‘BYPASS’.

So let’s say the names of the agents are base_agent and other_agent. This is what I have in my env -


function void connect_phase (uvm_phase phase);
    super.connect_phase(phase);
    other_agent.monitor.mon_analysis_port.connect(base_agent.sequencer.bypass_port);
endfunction : connect_phase

Now I also have sequences which don’t need these connections. For these I don’t want to change the SUBSCRIBER type and leave it as it is.
