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
. . . Please any help will be apreciated :) Thank youLink Copied

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:
