Abstract

The invention discloses a method for estimating single particle crosstalk among multiple lines, which belongs to the technical field of crosstalk measurement and comprises the following steps of: 1, determining lumped RC coupling interconnection line model parameters; 2, constructing a single particle crosstalk equivalent circuit; 3, calculating the response voltage of the disturbed line under theindependent action of each disturbed line; 4, establishing a disturbed line comprehensive single particle crosstalk estimation model; and step 5, determining crosstalk peak voltage and pulse width. According to the invention, the admittance rule is defined; the SET equivalent circuit, the voltage basic law, the substitution theorem and the superposition theorem are utilized to establish the method for estimating the single-particle crosstalk between the multiple lines, the analytical expression of the peak voltage and the pulse width of the single-particle crosstalk is given through derivation operation and Taylor formula expansion, and the waveform and the noise peak of the single-particle crosstalk between the multiple lines can be accurately estimated.

Description

technical field [0001] The invention relates to the technical field of crosstalk measurement, in particular to an estimation method for single event crosstalk between multiple lines. Background technique [0002] With the rapid development of space technology, nuclear science and electronic technology, more and more advanced microelectronic devices are applied to electronic systems of aviation, spaceflight and strategic weapons. Withstood the severe test of space radiation. According to statistics, from 1971 to 1986, 39 foreign geostationary satellites had a total of 1589 faults, of which the faults caused by space radiation accounted for 71%, and among these faults, single event effects (Single Event Effect, SEE) accounted for 1589 faults. 55%. Among the failures of my country's six geostationary satellites, 40% are related to space radiation. In addition, the latest statistics of spacecraft failures at home and abroad show that among the failures caused by the space env...
