Error 20445 in Tri Speed Ethernet IP for Stratix 10

Hi,

There are 2 possibility that I can think of.

1. You didn't assign the refclk pin to use "dedicated refclk" pin as indicated in the error message
2. Did you assign the 2 TSE IP instance into same IO bank ?

• This will caused the error as stated in page 170, chapter 7.2. Sharing PLLs in Devices with LVDS Soft-CDR I/O
  • https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug_ethernet.pdf
  • You need to split them into different IO bank

Thanks.

Regards,
