Hi Cris72,

I read the ideas mentioned by you.Below are some of the clarification regarding tha----

1.We are driving LEDs directly by the FPGA (with series resistance).LED draws 10mA current typically.

2.Device is getting damaged while operation.

3.We could no found any abnormal condition beween two FPGAs as mentioned by you.

4.We could not monitor the device heating before failure because device is getting failed during operation randomly.

Do you want the schematic of the device,in our design,for review?
