i am finding Short between VCC and GND pins of EP1K100 ACEX Series IC. What could be the reason other than ESD on I/Os which could lead to this .. any idea..?

To confirm this i have taken out all passives between power rails of IC and other connecting devices on Board but still there is short in power rails ( 2.5V and 3.3V) of IC .

I tkae it that you did not intend to open a new thread, but wanted to answer yesterday's thread?

Anyway, once the chip is showing this kind of damage, it's dead for good, not way to re-vive it. Did you check the design for use of 5V signals that possibly drive into clamping diodes that you may have switched on by accident?
