ssingh Posted October 8, 2012 Report Share Posted October 8, 2012 I am trying to build a dummmy uvm verification environment. The sequencer and driver work correctly but as soon as I add a monitor in the agent, I get the error - "Illegal assignment to class type monitor_base from class type sequencer_base". This error is produced at "mon = monitor_base::type_id::create("monitor",this);" in the build_phase function of the agent. This is a strange error as sequencer has nothing to assign to monitor. The code is given below for further reference. I am using Questa Sim 10.0d. class agent_base extends uvm_agent; `uvm_component_utils(agent_base) // Component Members sequencer_base seq; driver_base driver; monitor_base mon; function new(string name = "agent_base", uvm_component parent = null); super.new(name,parent); endfunction function void build_phase(uvm_phase phase); seq = sequencer_base::type_id::create("sequencer",this); driver = driver_base::type_id::create("driver",this); mon = monitor_base::type_id::create("monitor",this); // ERROR ! endfunction function void connect_phase(uvm_phase phase); driver.seq_item_port.connect(seq.seq_item_export); endfunction : connect_phase endclass: agent_base Quote Link to comment Share on other sites More sharing options...
