New ContributorI have a design using EP4CE15F23C9L which has 1.2 V connected to VCCINT (core voltage) instead of 1.0 V. This design is in production and has been operational for almost 10 years. I am wondering what kind of problems/effects this will have.
I believe this would have positve effects on setup timing but not sure how much - I am currently rewriting some functionality for this and setup timing is violated according to TimeQuest.

Frequent ContributorHi ,
From the datasheet of Cyclone 4 ,the maximum voltage for Vccint maximum voltage is 1.8V. page no:2 of the datasheet
https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyclone-iv/cyiv-53001.pdf
So may be that is the reason for the device is not going bad,
setup timing is violated according to TimeQuest
What is the violation
