Stratix III Device Handbook, Volume 1
The Stratix III TSD, located in the top-right corner of the die, requires two pins for
voltage reference. Connect the TEMPDIODEP and TEMPDIODEN pins to the external
analog-to-digital converter, as shown in
Figure 16–2. TEMPDIODEP and TEMPDIODEN External Pin Connections
The TSD is a very sensitive circuit which can be influenced by the noise coupled from
traces on the board, and possibly within the device package itself, depending on
device usage. The interfacing device registers temperature based on milivolts of
difference as seen at the TSD. Switching I/O near the TSD pins can affect the
temperature reading. Altera recommends you take temperature readings during
periods of no activity in the device (for example, standby mode where no clocks are
toggling in the device), such as when the nearby I/Os are at a DC state and the clock
networks in the device are disabled.

As process geometries get smaller, power and thermal management is becoming more
crucial in FPGA designs. Stratix III devices offer programmable power technology
and selectable core voltage options for low-power operation. Use these features, along
with speed grade choices, in different permutations to get the best power and
performance combination. Taking advantage of the silicon, the Quartus II software is
able to manipulate designs to use the best combination to achieve the lowest power at
the required performance.
For thermal management, use the Stratix III temperature sensing diode with an
external analog-to-digital converter in production devices. This allows you to easily
incorporate this feature in your designs. Being able to monitor the junction
temperature of the device at any time also allows you to control air flow to the device
and save power for the whole system.
