Problems solved by technology

[0004] In the design of radio frequency integrated circuits, simulation is an essential content, and the results of the simulation will directly affect the design of the integrated circuit. If the results of the simulation deviate greatly from the actual, the designer has to redesign the integrated circuit. It not only increases the product development cycle, but also increases the cost. The prerequisite for simulation is to do necessary processing on the layout of the designed integrated circuit. In the calculation of the Green's function matrix in simulation, it is necessary to calculate the direction of the current. This requires triangulation of the layout, and the quality, accuracy, and efficiency of the triangulation will have a great impact on the simulation

Embodiment Construction

[0074] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0075] Such as figure 1 As shown, the present invention has designed a kind of method of radio frequency integrated circuit triangulation mesh division, comprises the following steps:

[0076] (1) According to the coordinates of the device port, check whether the position of the device port is correct, if not, exit;

[0077] (2) Merge the vias in each via layer to reduce simulation time;

[0078] Among them such as figure 2 As shown, since the vias in the via layer are rectangular and have no bias, step (2) includes the following steps:

[0079] (a) Process all vias in each via layer so that the starting point and direction of the vias in all via layers are unified;

[0080] (b) For each via layer, take one of the vias as the via ①;

[0081] (c) obtaining the length of the shortest side of the via hole in the via l...

Abstract

The invention relates to a radio-frequency integrated-circuit triangular mesh generation method which is realized by cutting a metal layer into rectangles and polygons, respectively carrying out triangular mesh generation processing for rectangles and polygons generated by cutting based on preset maximum width of triangular mesh edges, and finally generating triangle point indexes and edge indexes and classifying respectively triangles with a same current at each layer. According to the invention, the designed radio-frequency integrated-circuit triangular mesh generation method can not only assist in improving quality and efficiency of triangular mesh generation, but also can assist in increasing electromagnetic field simulation speed.

Description

technical field [0001] The invention relates to a method for subdividing triangular grids of radio frequency integrated circuits, which provides necessary preconditions for electromagnetic field simulation. Background technique [0002] In recent years, wireless communication technology has developed rapidly, wireless products are widely used in all aspects of people's lives, and higher requirements are put forward for radio frequency integrated circuits, requiring better signal processing capabilities and shorter product development cycles. [0003] Radio frequency integrated circuits are mainly composed of transistor active devices and passive devices such as inductance and capacitance. According to the traditional design method, the designer first formulates the performance parameters of radio frequency integrated circuits according to the system requirements, determines the circuit structure, draws the circuit schematic diagram, and uses circuit simulation to determine T...
