Description
You may see this error if you implement an Arria® 10 “N” channel DPA LVDS design using a single 1 channel instance stamped multiple times in external pll mode.
Resolution
This configuration of single instances stamped multiple times is not supported using external pll mode. If an 8 channel design is required using external pll mode then a value of 8 channels must be selected in the Altera LVDS SERDES IP.
