    Hi,


    Thank you for reaching out to Intel FPGA Community.


    As far as I concern, only Stratix 10 among other Stratix devices has the Schmitt trigger functions. You can refer here Do Altera device input buffers have built-in Schmitt triggers? which mentioned that the Altera legacy devices that offer optional Schmitt triggers on the input buffers for user I/O pins are the MAX® II and MAX V device families only.


    Regards,
