摘要:
A logic design tool, a tool for analyzing soft error sensitivities in logic, and a program product for logic design. A particle generator simulates events likely to occur for a given operating environment. A pre-characterizer provides circuit block responses to simulated events. A circuit response simulator simulates events in a logic design and provides an indication of soft error sensitivity for the design. Based on the soft error sensitivity indication, the design may be modified to reduce the overall soft error sensitivity.

Aspects of the invention relate to a programmable heavy-ion sensing device for accelerated DRAM soft error detection. Design of a DRAM-based alpha particle sensing apparatus is preferred to be used as an accelerated on-chip SER test vehicle. The sensing apparatus is provided with programmable sensing margin, refresh rate, and supply voltage to achieve various degree of SER sensitivity. In addition, a dual-mode DRAM array is proposed so that at least a portion of the array can be used to monitor high-energy particle activities during soft-error detection (SED) mode.

An integrated circuit, method of forming the integrated circuit and a method of testing the integrated circuit for soft-error fails. The integrated circuit includes: a silicon substrate; a dielectric layer formed over the substrate; electrically conductive wires formed in the dielectric layer, the wires interconnecting semiconductor devices formed in the substrate into circuits; and an alpha particle emitting region in the integrated circuit chip proximate to one or more of the semiconductor devices. The method includes exposing the integrated circuit to an artificial flux of thermal neutrons to cause fission of atoms in the alpha particle emitting region into alpha particles and other atoms.
摘要:
A method and system for mitigating the impact of radiation induced in a data processor incorporating integrated circuits. The method comprises the steps of determining the location of the data processor, determining a set of radiation sources and intensities at that location, and estimating the soft error rate of the data processor as a function of the determined radiation intensities and geometric characteristics of said integrated circuits to provide an estimate value. The data processor is modified (either hardware or software) in response to the estimate value at times the estimate value exceeds a predetermined value.
