On the MAX 10 device (10 M 08 series), we created a project in Quartus with VCCIO = 2.5 V in VCCIO 1 A / VCCIOB bank.
However, 3.3 V is connected to VCCIO1A / VCCIOB on the actual machine.
In this case, what kind of risk do you have?
Thank you for the question ,
Let me rephrase your question to make sure i understood correctly,
In quartus project assignment you mention as 2.5V as VCCIO whereas you connected the VCCIO as 3.3V, correct ?
if yes , you would like to make sure the VIL/VIH and VOL and VOH is compatibility between the interfaced input and output.
if no, can you please clarify?
Thank you ,
