Method for establishing integrated circuit standard cell library

Abstract

The invention discloses a method for establishing an integrated circuit standard cell library. The method comprises the following steps of regularizing a standard cell layout with the minimum height;determining an extension datum line of the first type transistor and an extension datum line layout rule; determining a second type transistor extension datum line and an extension datum line layout rule; enabling all the layers above the extension datum line of the first type of transistor to extend to the specified height in the first direction; extending all levels above the extension datum line of the second type of transistor to a specified height in the second direction; determining an original point of the modified standard unit; and modifying all units in the standard cell library. According to the present invention, the height self-definition of the standard cell library of the integrated circuit can be realized only by developing a set of standard cell libraries with the minimumheight, and the development time of the standard cell libraries with different heights is reduced to a greater extent.

Description

technical field [0001] The invention relates to the field of integrated circuits, in particular to a method for establishing an integrated circuit standard cell library. Background technique [0002] In the field of semiconductor integrated circuit manufacturing, each process requires a set of corresponding standard cell libraries. Before tape-out, standard cells in the standard cell library need to be used for automatic logic synthesis and layout layout and routing. The advantage of the design method based on the standard cell library is that under a certain type of process node, the standard cell library only needs to be designed once and successfully verified, and can be reused in future designs, which greatly improves the Design efficiency, share the design cost. [0003] In the existing method, the establishment of the standard cell library is based on manual circuit construction and parameter modification. The development of the cell library is developed at a specifie...

[0003] In the existing method, the establishment of the standard cell library is based on manual circuit construction and parameter modification. The development of the cell library is developed at a specified height. The customer determines the height of the standard cell library according to the requirements of performance and power consumption. The development of the standard cell library The team develops the corresponding IP according to the above-mentioned height to meet the needs of customers. The development time of the standard cell library of each height in the industry takes 3 months, and there are problems of long response time and low efficiency.
