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 usage results in one global or regional clock resource for each group of identical
channels within a transceiver block.
For identical channels located across 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. Instead, it uses one tx_clkout signal for each
group of identical channels per transceiver block, resulting in higher clock resource
utilization.
Consider 16 identical transmitter channels located across four transceiver blocks,
as shown in
in each transceiver block to clock the write port of the transmitter phase
compensation FIFO in all four channels of that transceiver block, resulting in four
clocks resources (global, regional, or both) being used, one for each transceiver
block.
