DDR2 HPC2 Timing Simulation fails

Hello, i am trying to get the example design for the DDR2 Memory controller (HPC2 with ALTMEMPHY) to work. I have spent already a whole week on this issue, but I cant get it to run. I am using ...

Hi,

I made a funny observation this morning. I turned on the FPGA, uploaded the design and it worked well for a few minutes. No errors whatsoever. Then after a few minutes the error count goes up. Until it reaches the same error rate as before. So I assume that it has something to do with the temperature of the FPGA. But as I am concerned this shouldn't happen. Especially since the temperature is only about 43 °C (109 °F). Unfortunately I am not a electrical engineer, so I can hardly explain why this happens.

Best regards,

Martin
