Quartus 23.4 shows 0.0 BER but negative eye height values

Hi, I am running BER test for 2 FPGAs. I am transmitting from Tx pin of first FPGA and receiving on Rx pin on second FPGA. Using Quartus 23.4 here. Both are Agilex F-tile F-series FPGAs. There is ...

Hi Ranjith,

Could you try to increase the amplitude? Because I assume that the receiver side still have the minimum height limit on there.

From the analog side, the transmitter usually larger a bit than the receiver. The receiver side will have the minimum height limit on there and if the height is smaller than the minimum requirement, the signal might occur a lot error (BER).

Best regards,
