DDR3 IP simulation error Error: (vsim-10000) Unresolved defparamreference to 'power_s

While simulatintg the DDR3 SDRAM Uniphy IP example desing I am getting below given Errors :-

Error: (vsim-10000) ./..//submodules/altera_mem_if_hard_memory_controller_top_cyclonev.sv(1621): Unresolved defparam reference to 'power_saving_exit_cycles' in hmc_inst.power_saving_exit_cycles.# Region: /ddr3_eg_example_sim/e0/if0/c0# ** Error: (vsim-10000) ./..//submodules/altera_mem_if_hard_memory_controller_top_cyclonev.sv(1622): Unresolved defparam reference to 'mem_clk_entry_cycles' in hmc_inst.mem_clk_entry_cycles.# Region: /ddr3_eg_example_sim/e0/if0/c0# ** Error: (vsim-10000) ./..//submodules/altera_mem_if_hard_memory_controller_top_cyclonev.sv(1623): Unresolved defparam reference to 'priority_remap' in hmc_inst.priority_remap.# Region: /ddr3_eg_example_sim/e0/if0/c0# ** Error: (vsim-10000) ./..//submodules/altera_mem_if_hard_memory_controller_top_cyclonev.sv(1624): Unresolved defparam reference to 'enable_burst_interrupt' in hmc_inst.enable_burst_interrupt.# Region: /ddr3_eg_example_sim/e0/if0/c0# ** Error: (vsim-10000) ./..//submodules/altera_mem_if_hard_memory_controller_top_cyclonev.sv(1625): Unresolved defparam reference to 'enable_burst_terminate' in hmc_inst.enable_burst_terminate.# Region: /ddr3_eg_example_sim/e0/if0/c0# ** Error: (vsim-10000) ./..//submodules/ddr3_eg_example_sim_e0_if0_p0_acv_hard_memphy.v(676): Unresolved defparam reference to 'm_hphy_ac_rom_init_file' in hphy_inst.m_hphy_ac_rom_init_file.# Region: /ddr3_eg_example_sim/e0/if0/p0/umemphy# ** Error: (vsim-10000) ./..//submodules/ddr3_eg_example_sim_e0_if0_p0_acv_hard_memphy.v(677): Unresolved defparam reference to 'm_hphy_inst_rom_init_file' in hphy_inst.m_hphy_inst_rom_init_file.# Region: /ddr3_eg_example_sim/e0/if0/p0/umemphy

The simulation is done as explained in the "emi.pdf" chapter 10 Simulating Memory IP

Software used for simulation is ModelSim ALTERA STARTER EDITION 10.0c.

So please let me know what could be the possible Fix to these Errors?
