    I think that is the problem.

    I had the same error when using pins from the same bank in two RX SERDES IP. Error got solved after changing the pins location of the inputs of one of the receivers, so using only one receiver IP for each bank works in my case.

Hi,

Unfortunately, i cannot share the project file. I use Quartus Prime Pro 22.1. As i understand there is only one IO_SERDES_DPA location per bank so when i try to instantiate more than one RX SERDES IP with different parameters it cannot be placed. Is this the problem ?

Regards

Manolis
