Embodiment Construction

[0080] As mentioned in the background technology section, in the prior art, when generating the schematic diagram and layout of the differential circuit, manual drawing is used, and in the process of generating the schematic diagram and layout of the differential circuit, multiple checks and modifications are required , and the modification of each layer is manually modified, which seriously reduces the generation efficiency of the differential circuit.

[0081] In view of this, an embodiment of the present invention provides a method for generating a differential circuit parameterization unit, including:

[0082] Step 1: Select a differential circuit sample, and obtain preset parameter values ​​of the differential circuit sample. The preset parameters include: the number of MOS transistors in the differential circuit sample, the length of the MOS transistor, the width of the MOS transistor, and the the number of gate folds;

[0083] Step 2: Calculate the width of each gate i...

Abstract

One embodiment of the invention discloses a method and system for generating difference circuit parameterization units. Difference circuit schematic diagrams and layouts can be generated according to preset parameter values in a selected difference circuit sample and stored correspondingly to generate the difference circuit parameterization units so that the difference circuit parameterization units can be called directly according to the preset parameter values of the difference circuit to be formed in the later specific application to generate the schematic diagrams and layouts of the difference circuit to be formed. Thereby the problem that the generation efficiency is low due to the manual drawing and modifying the schematic and the layouts of the difference circuit in the prior art is solved, and the generation efficiency of the differential circuit is remarkably improved.
