MAX10 Damaged with clk pin pulled down



On my new design, I observe recurring FPGA MAX10 failures. The board has 6 similarly polarized FPGAs 10M08SCU169I7G . The FPGAs are programmed correctly, run fine for a few hours and then one of the 6 breaks for no apparent reason. After replacement, the card is functional again and I no longer observe any failure.
On two occasions, I observed a similar failure, the clock signal seems to be pulled low by the FPGA. The clock pin used is a CLK0n, or CLK1p used in 0-3.3V and configured in 3.3 V Schmitt Trigger

I did not observe any other pins pulled low.

I would focus more on the production problems of the card, however, I am surprised to observe the same failure several times. Do you know of any problem of this type? Do you have any leads to guide us?

Thank you

You might want to

1) Check if there is any chance you have violated the absolute max spec: (Table 4)

2) Check if it could be due to ESD.
