100g MAC licensing

Good day!

I want to implement project with 100g ethernet subsystem ip core on custom ultrascale+ board or may be using alveo u200 also. I read that autonegotiation and link training needs additional fee based license due to next page:

https://www.xilinx.com/products/intellectual-property/cmac_usplus/cmac_usplus_order.html

 

I can't understand will my board establish connection to PC with 100g NIC or router without fee based license? Or after achieving bit file only loopback in FPGA is availablable with free subsystem license?

Re: 100g MAC licensing

Hey @slipknotchik,

It depends on the requirements of the link partner. AN/LT is required for 100GBASE-KR4 or 100GBASE-CR4 applications. For all other applications, such as
100GBASE-SR4, it is not used. This information is available on page 8 of PG203. What are the specifications of your NIC and/or router?
