What does the i_txclkdivrate input port in the GTS PMA/FEC Direct PHY IP do when SATA/SAS configuration rules are selected?

Description

Due to a problem in the Quartus® Prime Pro Edition software version 25.3.1, the i_txclkdivrate input port to be unintentionally exposed when SATA/SAS mode is selected via the PMA configuration rules in the GTS PMA/FEC Direct PHY IP. This port does not require user control when operating in SATA/SAS mode.

Resolution

To work around this problem, you can tie this port to GND (ground) when operating in SATA/SAS mode.

This problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Edition software.

The port will be removed and will be controlled internally by the GTS PMA/FEC Direct SIP.
