Problems solved by technology

However, it generally takes a long time to obtain good results from electromagnetic simulations, so it is not easy to obtain a definite solution in a short period of time
This is also very undesirable for the layout design of semiconductor circuits

Embodiment Construction

[0026] figure 1 is a schematic flowchart of a layout method according to an embodiment of the present invention. First, form data of at least one component is input in step S100. The element may be a capacitive element, an inductive element, a varactor element, a transformer, or other matched resistive elements and transistors, and the like. Regarding the shape data of the component, taking the capacitor component as an example, it can be the shape of multi-layer metal layer stacking, the shape of the inductor, etc.

[0027] In step S102, after the component and its required shape data are input, then input the value of at least one radio frequency parameter corresponding to the component. The radio frequency parameter may be an operating frequency and a corresponding quality factor (quality factor, hereinafter referred to as Q factor) and the like. In addition, when considering the frequency response of the component under radio frequency, the value of the component itself...

Abstract

An integrated circuit layout method with radio frequency components includes the following steps. The shape data of at least one radio frequency component and the value of at least one radio frequency parameter corresponding to the radio frequency component are input. Based on the numerical and morphological data of the RF parameters, a frequency response result is generated. When the frequency response results meet the required specifications, the layout of the integrated circuit is performed according to the frequency response results. When the frequency response result does not meet the required specification, another value of the at least one radio frequency parameter is re-inputted.

Description

technical field [0001] The invention relates to a method for layout of integrated circuits, in particular to a method for layout of integrated circuits with radio frequency components. Background technique [0002] Integrated circuit layout is a very important part of the fabrication of integrated circuits. Under the miniaturization requirements of integrated circuits, how to configure the maximum number of components in a limited area and meet the specification requirements is a very important part. However, most of the current layout designs focus on area optimization, etc., and relatively do not consider the layout design when there are radio frequency components such as capacitors, inductors, varactors, etc. in the integrated circuit. [0003] Taking capacitors as an example, it takes too long to design by pre-simulation or post-simulation. If the designed specifications do not meet the requirements, it is necessary to redesign or change the layout arrangement, which i...
