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 .

Hi Jens,

Thank you for the answer..

You are correct..that I was trying for premier support...so posted it again by mistake..​

​

And Yes I have checked design for 5V tolerent ​ standard and it is designed for 3.3V standard.

And if I am not wrong, if this is due to quartus design issue then problem should be consistent rt...?

Sorry forgot to mention in post...FYI..it is happening ​only in around 10% of boards i.e 8/80 boards..
