Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 17.1 and earlier, you might encounter this warning during timing analysis when instantiating multiple instances of the Transceiver Native PHY Intel® Stratix® 10 FPGA IP in your design.
The problem is specific to cases where the Transceiver Native PHY Intel® Stratix® 10 FPGA IP instance names includes square brackets contaning more than one digit.
"my_instance.u0" would work fine.
"my_instance.u0" would result in the error
Instance names containing square brackets are a common result of using generate statements to instantiate multiple instances of the same component.
To work around this problem, ensure that your Transceiver Native PHY Intel® Stratix® 10 FPGA IP instance names do not include square brackets containing more than one digit.
This problem is scheduled to be resolved in a future release of the Intel Quartus Prime Pro Edition Software.
