gate level simulation problem

Hello, I am working on a DVI interface, I am sending video data serially, every thing work well, apart from the post place and route simulation, I have this worning and I didn't get any thing.# ** Warning: (vsim-8683) Uninitialized out port /dvi_maintop/altera_internal_jtag/tdo has no driver.# This port will contribute value (U) to the signal network.# Region: /dvi_maintop# ** Warning: (vsim-8683) Uninitialized out port /dvi_maintop/altera_internal_jtag/tmsutap has no driver.# This port will contribute value (U) to the signal network.# Region: /dvi_maintop# ** Warning: (vsim-8683) Uninitialized out port /dvi_maintop/altera_internal_jtag/tckutap has no driver.# This port will contribute value (U) to the signal network.# Region: /dvi_maintop# ** Warning: (vsim-8683) Uninitialized out port /dvi_maintop/altera_internal_jtag/tdiutap has no driver.# This port will contribute value (U) to the signal network.# Region: /dvi_maintop# ** Warning: (vsim-8683) Uninitialized out port /dvi_maintop/\serdes_instG|altgx_core_alt4gxb_component|cal_blk0\/nonusertocmu has no driver.# This port will contribute value (U) to the signal network.# Region: /dvi_maintop# ** Warning: (vsim-8683) Uninitialized out port /dvi_maintop/\serdes_instG|altgx_core_alt4gxb_component|cent_unit0\/control_top_0/m_map/refclkdividerdprioout(1 downto 0) has no driver.# This port will contribute value (UU) to the signal network.# Region: /dvi_maintop

    it sounds like there are some ports you have forgotten to connect up in your testbench.

    Thank you for your help, I've connected all ports in test bench but I still have this errors and wornings, seems like no librarie is taken in account:

    what could be causing these errors ?

    thank you again...
