Why am I seeing High Severity DA warning: "Multiple Clock Domains Driving a Synchronizer Chain" after enabled Transceiver Toolkit in Dual-Simplex Parallel loopback Design Example?

Description

Due to a problem in the Quartus® Prime Pro Edition software version 26.1.1, you may see a DA warning: "Multiple Clock Domains Driving a Synchronizer Chain" in the compilation report for the GTS SDI II Dual-Simplex Parallel Loopback design example when the transceiver toolkit is enabled.

Resolution

This DA Warning can be ignored in 26.1.1, and this problem is scheduled to be fixed in a future release of Quartus Prime Pro Edition software.
