Hi,

I tried to run the code suggested by you but I am getting some errors.It is from the design example from http://www.bitec.ltd.uk/hsmc_dvi.html

DVI 1080P Loop-through CIV

This sof updates the EDID EEPROM on the HSMC DVI board to correctly report 1080P@60

They are

Error: Node instance "auto_inst" instantiates undefined entity "alt_vip_vfb_0_GN"

Error: Quartus II Analysis & Synthesis was unsuccessful. 1 error, 802 warnings
