The temperature-sensing diode works for the entire operating range, as
shown in
The temperature sensing diode is a very sensitive circuit which can be
influenced by noise coupled from other 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 disable clock networks in the device.
Stratix II devices offer on-chip circuitry for automated checking of single
event upset (SEU) detection. Some applications that require the device to
operate error free at high elevations or in close proximity to Earth’s North
or South Pole require periodic checks to ensure continued data integrity.
