Abstract

The invention discloses an IBIS-based integrated circuit total dose effect modeling method. The IBIS-based integrated circuit total dose effect modeling method comprises the steps of performing irradiation on an original electronic device by adopting different target accumulated doses; performing data measurement and model extraction on the irradiated original electronic device, and establishing an IBIS model database of the electronic device under all the target accumulated doses; under the condition of giving a total irradiation dose D, performing interpolation operation on the established model database of the device according to the total irradiation dose D to obtain VI and VT interpolation data under the irradiation dose, and building an IBIS model according to the interpolation data, namely, an IBIS irradiation total dose effect model of the device under the irradiation dose. According to the method, the influence of irradiation conditions on PCB signal integrity is considered based on original PCB signal integrity analysis, and model support is provided for performing simulation analysis of PCB signal integrity problem under the irradiation condition.

Description

technical field [0001] The invention belongs to the technical field of modeling of device radiation effect models, in particular to an IBIS-based method for modeling the total dose effect of integrated circuits. Background technique [0002] At present, in order to meet people's requirements for miniaturization and multi-function of electronic equipment, the printed circuit board (PCB) is developing towards high speed, high density and high integration. When the signal rate and component density increase to a certain level, the parasitic effect on the PCB will cause noise and interference on the transmission signal, and the PCB will not work well. This requires good signal integrity simulation design in the PCB design stage of electronic product development. The device model used in simulation will directly affect the accuracy of simulation. The device model widely used in signal integrity simulation in the industry is the IBIS model (a method for quickly and accurately mo...
