Acknowledgement
The Intel Quartus Prime Pro Edition software detects the presence of instantiated
transceiver Native PHY IP cores and automatically inserts the TRS. The
tx_reset
and
rx_reset
inputs, either generated by you or through the reset controller, are
received by the Local TRS. The Local TRS also forwards the request to the master TRS
for scheduling. TRSs work together to schedule all the requested RS-FEC/PMAIF resets
and provide acknowledgment for each request. Use either the reset controller inside
the transceiver PHY or your own reset controller with the transceiver reset in manual
mode. However, for the TRS to work correctly, the required timing duration must be
followed.
Note:
The master and local TRS IP is an inferred block and is not visible in the RTL. You have
no control over this block.

The

signals apply the associated transceiver resets.
You can use the Native PHY's AVMM interface to do a PMA analog reset or to enable
and disable the PMA.
You have the option to use
tx_reset
and
rx_reset
as the input controls if you
enable independent TX and RX reset, or you can use
reset
as the input to control
both TX and RX if you disable independent TX and RX reset. The diagrams "Reset
