Start with looking at File: ../utmi/utmi_agent.sv Line: 24

What is on that line, and how are the identifiers declared on that line.

Generally in an Agent, We just declare the handles for the sequencer, driver and monitor, and the build we call the create method after if we move to connect phase the seq_item_port and seq_item_export we use to connect, the sequencer and driver.

As per the error from my understanding you have error there keeping that aside if we move further the “uvm_seq_item_pull_imp #(class” this is begin an use generally, we use get_next_item and item_done these are implemented by uvm_blocking_get_imp by the TLM of sequencer and its begin called in the driver of TLM of uvm_blocking_get_port. So, the error pull_imp which might be implenting the pull() there might be an declaration error in driver or keeping them run_phase correctly.

Thanks,
