Due to a problem in the Intel® Quartus® Prime software version, 18.1 and earlier, instantiating multiple instances of these IPs might cause fitter warnings of the following format: “Overwriting the previous definition of xyz module”. When the IP has different configurations, this could impact the functionality of the IP.
Low Latency 100G Ethernet Intel® Stratix® 10 FPGA IP, 25G Ethernet Intel® Stratix® 10 FPGA IP, H-Tile Hard IP for Ethernet Intel® Stratix® 10 FPGA IP and E-Tile Hard IP for Ethernet Intel® Stratix® 10 FPGA IP
This problem has been fixed starting in the Intel® Quartus® Prime revision v18.1.1.
