Is there a risk of overheating?


I am running a quite power-demanding design on my XEM6310, currently at 100MHz. Is it save to gradually increase frequency or do I risk to overheat and damage the FPGA at some point?


You will definitely want to monitor the FPGA and other components on the board. With FPGA densities today, it is very possible to overwhelm the thermal dissipation capabilities.

How do I monitor the FPGA? The XEM6310 does not seem to have any temperature sensors.

Any of the standard ways to measure temperature apply…

Something like this:

Or this…

Or even just a finger.

Of course, the most thorough way is by using the Xilinx power estimation tool with accurate input information to generate a thermal dissipation estimate. From that, you can determine if you need active heat removal.

I too am like you. I thank the opinions of people
