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

Description

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

Resolution

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

This is already fixed in Quartus® Prime version 17.1.
