Error: The Maximum channels supported is 8 for LVDS variant Or Error: “Number of channels” (NUM_CHANNELS) 12 is out of range: 1-11


You may receive above error message when select the port number greater than 8 and transceiver type as LVDS I/O for Triple Speed Ethernet IP Core in Quartus® Prime version 17.0.2 including patch 2.05 or Quartus® Prime version 17.1.


The Triple Speed Ethernet IP with LVDS I/O interface can only support up to 8 ports. Therefore, port number larger than 8 is not a valid option and those options will be removed in a future version of Quartus® Prime.
