  2. In Tcl console, invoke reset_simulation command to clean the simulation directory.
  3. In Tcl console, invoke launch_simulation command to run the simulation.
  4. In Tcl console, invoke the following command:
    current_scope /axi_vip_0__exdes_adv_mst_active_pt_mem__slv_passive/DUT/ex_design/axi_vip_passthrough/inst/IF/PC


  5. Double-click the scope PC to open the source code.
  6. Observe that line number 1144 onwards all the property declarations and assertions have been used.
