The "EP2C35F484I8N" device is used my project. It is very good working on low temperature about 20'C, but is not working on high temperature about 45'C.
Why not working on high temperature? What is difference points on low temp vs high temp?
In my opinion, may be, this result is caused by propagation delay on temperature and async coding style.
On high temperature, "Action trigger signal" is LOW, always. (QuatursII 12.1's time options is default setting.)
