Cold Temperature Issue

Hallo,

We used the Agilex5 device in AS configuration connect to external QSPI Flash.

We apply Smart VID interface at the device demands. 

When we perform Cold power up at -40C the device is not configured, It seemed the device is not  output from the POR, No traffic on the PMBus.   

Power sequence and voltage ramp time and levels are OK.

Please advise

Thanks

Asaf
