Radiation tolerance, including the behavior under single events (SEU) and total cumulated dose (TID) is a main issue for some applications in Space operations. In this specific case, the design of most of the technology elementary devices has to be modified and adapted. The corresponding modeling is performed on test vehicles, out of which the created devices will form a new design library.
Such specific modeling process is validated by SEU and TID tests applied on the test vehicles; the outcome is a rad-hard full design kit including analog and digital cells for the targeted technology. This allows further mixed-signal designs with a fully predictable behavior with regards to radiations.
