Why am I seeing simulation failures for GTS Ethernet Hard IP with Auto-Negotiation and Link Training (AN/LT) and ECC-enabled designs? - Why am I seeing simulation failures for GTS Ethernet Hard IP with Auto-Negotiation and Link Training (AN/LT) and ECC-enabled designs? Description Due to a problem in the Quartus® Prime Pro Edition software version 24.3.1, you may see simulation failures for GTS Ethernet Hard IP with Auto-Negotiation and Link Training (AN/LT) enabled designs, which have ECC-enabled. Resolution There is no workaround for this problem for ECC enabled simulations in the Quartus Prime Pro Edition software version 24.3.1 and earlier. This problem is fixed beginning with the Quartus Prime Pro Edition software version 25.1.
