Limitations of the Quartus II Software-Selected Transmitter Phase Compensation FIFO Write
Clock
The Quartus II software uses a single tx_clkout signal to clock the transmitter phase
compensation FIFO write port of all identical channels within a transceiver block.
This results in one global and/or regional clock resource being used for each group of
identical channels within a transceiver block.
For identical channels located across the transceiver blocks, the Quartus II software
does not use a single tx_clkout signal to clock the write port of the transmitter phase
compensation FIFOs for all channels. It uses one tx_clkout signal for each group of
identical channels per transceiver block. This results in higher global and regional
clock resource usage.

blocks. The Quartus II software uses tx_clkout from Channel 0 in each transceiver
block to clock the write port of the transmitter phase compensation FIFO in all four
channels in that transceiver block. This results in four global and/or regional clock
resources being used, one for each transceiver block.
