Error (169175): Pin &ltname&gt with LVDS I/O standard needs a differential output buffer which is not available on location &ltname&gt. - Error (169175): Pin &ltname&gt with LVDS I/O standard needs a differential output buffer which is not available on location &ltname&gt. Description You may get this error message during compilation in the Quartus® II software if you have assigned the IO standard LVDS to an IO pin which does not support true LVDS outputs. Resolution To avoid this error use the Emulated LVDS standard assignment LVDS_E_3R or LVDS_E_1R . Note: To use emulated LVDS standards you need additional resistors on your board. Refer to the handbook of the respective target device for more information.
