Embodiment Construction

[0018] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] see figure 1 , figure 1 It is a flowchart of a method for obtaining electromagnetic radiation characteristics of chip-level circuits by using electromagnetic simulation software provided by an embodiment of the present invention. exist figure 1 In the illustrated embodiment, the method includes step S101 to step S103.

[0020] In step S101, the electromagnetic simulation software obtains the physical layout information of the chip-level circuit through a script, and generates a 3D model. For example, a 3D model is generated according to the thickness and material information of the mask layer in the GDS file corresponding to the ITF file in the process library in the electromagnetic simulation software. During the process of generating the 3D model, one or more of translation mask layer, extension mask layer, structure ...

Abstract

The invention discloses a method and a device for acquiring the electromagnetic radiation characteristic of a chip-scale circuit by adopting electromagnetic simulation software. The method comprises the following steps: acquiring the physical layout information of the chip-scale circuit through the electromagnetic simulation software to generate a 3D model; performing preprocessing on the 3D model by using a script corresponding to the electromagnetic simulation software; simulating the 3D model by using the electromagnetic simulation software, and outputting the electromagnetic characteristic of the chip-scale circuit. The physical layout information is acquired via the script, and simulated electromagnetic characteristic is automatically generated after preprocessing of the 3D model, so that the electromagnetic characteristics of chip-scale circuits of different processes and different structures can be simulated conveniently, and high operability and repeatability are achieved.

Description

technical field [0001] The invention relates to the technical field of analyzing chip-level integrated circuits, in particular to a method and device for obtaining electromagnetic radiation characteristics of chip-level circuits by using electromagnetic simulation software. Background technique [0002] As the operating frequency of integrated circuits continues to increase, the main frequency of some signals has reached several GHz. On the one hand, the electromagnetic effect of the chip itself will become more and more obvious, on the other hand, the electromagnetic noise introduced by the surrounding environment will become non-negligible. The traditional design method does not consider the change of the electromagnetic field, so it is difficult to provide accurate simulation results at high frequencies, and it is also impossible to verify the working conditions of the chip in the extreme electromagnetic field environment. Therefore, it is very necessary to introduce ful...
