10.1 Timing - Does the timing report take the TID limit into account for Xilinx QPro Radiation-Tolerant ("radiation-hardened") devices?

Description

Does the timing report take the TID limit into account for Xilinx QPro Pro Radiation-Tolerant (also known as "Radiation-Hardened") FPGAs?

Solution


The following information pertains only to Total Ionizing Dose specifications in QPro Radiation-Tolerant devices, and does not apply to Single-Event Upset (SEU).

Total Ionizing Dose is a specification that pertains only to devices in space and other high-radiation environments (nuclear reactor cores, particle accelerators). Devices in environments where human beings can safely work do not have high enough radiation levels to contribute to TID, even in the presence of environmental neutrons.

The timing report does take into account the TID limit of Xilinx QPro devices, in the same way that it takes into account the full temperature range, the full operating voltage range, and the full range of acceptable process variations for a device.

All Xilinx devices are guaranteed to perform to data sheet specifications across the full range of operating conditions that are specified for the device.

Total Ionizing Dose is an operating specification like any other; consequently, the timing report does not have to be derated for higher dose levels.
