Problems solved by technology

For example, to review the DRC (Design Rule Check) results of the chip, each designer needs to spend the same amount of time to complete the process of importing the layout data from the hard disk, which is inefficient and takes up a lot of memory.
[0004] Although multiple people can review through the traditional method of shared desktop such as VNC, due to the limitation of one desktop, all personnel cannot perform parallel operations at the same time, which also greatly reduces the efficiency of review

Embodiment Construction

[0033] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0034] figure 1 It is a flow chart of the review method of layout data according to the present invention, and the following will refer to figure 1 , to describe the review method of layout data in the present invention in detail.

[0035] In step 101, the imported layout data of the pre-reviewed layout is preprocessed in memory to obtain core data of the pre-reviewed layout and share the core data.

[0036] In this step, the review system receives the layout data of the pre-reviewed layout imported by the first reviewer from a storage device such as a hard disk, sorts the layout data in the memory according to the position information of the graphics, and sorts th...

Abstract

A layout data review method and system and a storage medium are disclosed. The method comprises the following steps: pre-processing the imported layout data of a pre-review layout in a memory to obtain the core data of the pre-review layout and share the core data; building virtual addresses based on where the core data resides and accessing the core data through user space. The layout data reviewmethod, and system and the storage medium of the invention reasonably distribute and utilize the memory to directly access the memory data through the mapping of the virtual addresses, so as to improve the speed and efficiency of the large layout data import, browse and edit cooperated by multiple persons, and are particularly suitable for the layout data review of large-scale integrated circuitsby multiple persons.

Description

technical field [0001] The invention relates to the technical field of EDA design, in particular to a layout data review method, system and storage medium. Background technique [0002] With the development of semiconductor manufacturing technology and the expansion of integrated circuit design scale, more wiring layers and graphics are included in the chip layout, and the amount of data that needs to be processed is also increasing. Resource utilization presents challenges. [0003] It takes longer for designers to open layout data and consumes more memory. Especially in scenarios like team design, where multiple designers are required to open, browse and even edit the same layout at the same time. For example, when reviewing the DRC (Design Rule Check) results of a chip, every designer needs to spend the same amount of time to complete the process of importing layout data from the hard disk, which is inefficient and takes up a lot of memory. [0004] Although multiple p...
