Bug ID: 1507120119
IP: Altera S10 Temperature Sensor

Why is the Intel® Stratix® 10 MX and Intel® Stratix® 10 TX device internal Temperature Sensing Diode (TSD) read out always stuck at +25 degrees Celsius?


Due to a problem in Intel® Quartus® Prime Pro Edition version 18.1 and later, the internal TSD read out from Intel® Stratix® 10 MX and TX devices is always stuck at +25 degC. This only impacts the following production device variants:

Intel® Stratix® 10 MX 1650

Intel® Stratix® 10 MX 2100

Intel® Stratix® 10 TX 1650

Intel® Stratix® 10 TX 2100


This problem will be fixed in the future release of the Intel® Quartus® Prime Pro Edition software. For a temporary workaround, contact Intel® Premier Support.
