FPGA die temperature warning
Applies to:
When the measured FPGA die temperature reaches 87°C , these Coaxlink cards post a "FPGA
temperature is too high" Memento message.
The "FPGA temperature is too high" message is sent repeatedly every second until the measured
temperature decreases below 83°C or increases above 103°C.
TIP
Operation is still possible but is not recommended!
WARNING
When such event occurs, the user is invited to check and, possibly, improve
the card cooling in the host PC!
FPGA die temperature error
Applies to:
Random errors could occur in the FPGA if its core temperature becomes excessive. Therefore, for
security reasons, the stream acquisition is stopped when the measured FPGA die temperature
reaches 103°C!
The "FPGA temperature is too high; stopping operation to prevent damaging the card" Memento
message is sent repeatedly every second until the measured temperature decreases below 97°C.
TIP
Stopping the acquisition reduces significantly the heat production of the
FPGA. This action is aimed to reduce the die temperature, to prevent the
application against unexpected FPGA behavior and to prevent damaging the
card.
WARNING
When such event occurs, the user must immediately shut down the system
and revise the card cooling in the host PC before restarting!
