In reply to Ramakrishna Melgiri:
Your statement regarding ‘staying at time = 0’ is not precise enough. During runtime 0 the dynamic part of your testbench is built. After that the simulation starts. Because you say there are no errors and warnings I guess the testbench has been constructed. Can you please confirm?
All TLM components do not really consume time. Time consumtion is controlled by the driver and the monitor. Have a look to these components to identify the problem. My guess is your driver or monitor is not seeing a clock edge. Can you please check?
