10_100_1000 Mbps tri-mode ethernet MAC

Hello,I'm trying to make test bench with Vivado but without success because Cadence incisive is required to perform it.Now,closed Vivado and I open Cadence and put these files MAC_top.v in Core_Ethernet_35/ethernet_tri_mode/trunk/rtl/verilog Phy_sim.v in Core_Ethernet_35/ethernet_tri_mode/trunk/bench/verilog User_int_sim.v in Core_Ethernet_35/ethernet_tri_mode/trunk/bench/verilog host_sim.v in Core_Ethernet_35/ethernet_tri_mode/trunk/bench/verilog

and tb_top.v in /Core_Ethernet_35/ethernet_tri_mode/trunk/bench/verilog Launching simulation i can see only the clocks variate,no other.I think I need to add stimoulus but I can't find the files that have it. Can you help me?
