Embodiment approach

[0076] The standard cell library design inspection method proposed in the embodiment of the present invention can adopt the SKILL language and develop automatic splicing based on Virtuoso software. The purpose is to use standard cells, randomly select and sequentially splice into a rectangle, which is used to simulate the actual application scenario of the standard cell library to check the satisfaction of the design. Please refer to Figure 10 , another embodiment of the present invention provides a standard cell library design checking method, comprising the following steps:

[0077] Step S1: Statistical basic properties of the standard cell library: In the design library of standard cells containing all standard cell libraries, obtain and record each physical property of each standard cell (including name, width (L0), height (H0), pin name, etc.);

[0078] Step S2: Set the verification conditions: according to the coverage requirements and cell format, set the preset tota...

Abstract

The invention discloses a standard cell library design inspection method and system and a readable storage medium. The method comprises the following steps: setting a verification condition, selectingstandard units in a standard unit library by using a random selection mode, splicing and placing the standard units on a layout according to a random splicing mode until the verification condition ismet, and finally carrying out design inspection on the randomly spliced layout of the formed standard unit library. By means of the standard cell library design checking method, high-coverage-rate rule checking can be completed in the design stage of a standard cell layout, repeated work in the standard cell library building process is reduced, due to the fact that the method has full randomness,the coverage rate of the technical scheme is higher than that of the scheme in the prior art, and the probability of problems occurring when the standard cell library is used for splicing in the later period can be effectively reduced.

Description

technical field [0001] The invention relates to the field of integrated circuit design, in particular to a standard cell library design checking method and system and a readable storage medium. Background technique [0002] The standard cell library can be divided into layout library, symbol library, circuit logic library and so on according to the type. General standard cells include, but are not limited to, combinational logic, sequential logic, functional cells, and special-type cells. The standard cell library is the basic part in the back-end design process of integrated circuit chips. Using pre-designed optimized library cells for automatic logic synthesis and layout placement and routing can greatly improve design efficiency and speed up time to market. At present, the overall design process of the standard cell library includes the following steps: ① cell library definition and feature determination, determine the technical indicators of the cell library according ...
