Occasional ContributorS10 Native Phy SR or LR link type
Hi,
Nothing changes in Assignment editor.
In Stratix 10 L/H-Tile speak, SR (Short Reach) is chip-to-chip (low loss) , and LR (Long Reach) is backplane (high loss). So the changes will be in the PMA and its ability to TX & RX over different loss profiles. If you are transmitting over a backplane, or to another board, or lossy medium, use LR. If you are transmitting to the same chip (including optical module) use SR.
Thank you
