Description
In the Transceiver Toolkit in the Quartus® II software version 10.1, when using manual control panels for receiver, transmitter, or link, do not change the pseudo-random binary sequence (PRBS) pattern while the channel is running. Doing so may cause the system to go into an unexpected state. If this happens, the Transceiver Toolkit must be closed and restarted to continue using it reliably. Always stop the channel(s) before changing the PRBS pattern.
