Why do I see this warning message after enabled Transceiver Toolkit Debugging Features in GTS SDI II Serial Loopback Design Example?

Description

Due to a problem in the Quartus® Prime Pro Edition software version 26.1.1, you will observe below.

“warning check failed! > warning: no path is found satisfying assignment"

“set_max_skew -from get_registers auto_fab_0|alt_sld_fab_0|alt_sld_fab_0|stfabric|h2t1_fifo|in_wr_ptr_gray -to get_registers auto_fab_0|alt_sld_fab_0|alt_sld_fab_0|stfabric|h2t1_fifo|write_crosser|sync.u|din_s1 -get_skew_value_from_clock_period src_clock_period -skew_value_multiplier 0.800 - This assignment will be ignored.”

It happens when user enables the Transceiver Toolkit Debugging Features in GTS SDI II Serial Loopback Design Example. This problem happens due to the undefined path of the dc_fifo.sdc.

Resolution

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