“…Since every logic circuit works at a specific frequency, if the propagation delay changes while under radiation, the design could fail even before the device breakdown. As experimented in [20], the propagation delay degradation reached values of up to 1100% before the device failed. This kind of event, is the main source of failure related to TID for an user design.…”

“…Although the configuration memory on the ProASIC3e is susceptible to TID, a dose of up to 30 krad seems not to affect the FPGA implemented circuit [26]. The use of SRAMbased FPGA, at the present stage, have not been considered, mainly because the configuration memory is highly sensitive to SEEs.…”

“…For instance, there are several implementations of delay lines based on the embedded fast carry chain units in FPGAs, offering fine-grain resolution between the consecutive stages [44,40,92,163]. There are other implementations where the delay lines are based only on the chain of multiple logic gates, omitting the intermediate registers, however, usually requiring access to the I/O blocks of the FPGA for input stimuli and capture of output signal for the measurement of delay [63,130].…”

“…From a different aspect, they have also been used as sensors for temperature monitoring [22,27]. Another popular usage of delay lines is the assessment of TID effects [63,131,11,130,164]. An appealing application which differentiates them from ring oscillators, is the indirect monitoring of the functional integrity of a design running on the FPGA.…”
