I'm using Stratix III, IV and V devices.

Due to small glitch on PCB, I want to use the I/O with Schmitt trigger function.

But I don't which I/O support Schmitt trigger function.

Could someone please tell me how to find the related information?

Thank you very much.

In the follow web, Stratix series devides don't support Schmitt trigger function.

Does it right?

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.
