UVM Sequencer

UVM Sequencer

  • The sequencer controls the flow of request and response sequence items between sequences and the driver
  • Sequencer and driver uses TLM Interface to communicate transactions
  • uvm_sequencer and uvm_driver base classes have seq_item_export and seq_item_port defined respectively. User needs to connect them using TLM connect method.



A sequencer can be written by extending the uvm_sequencer parameterized with the seq_item type.
