Embodiment Construction

[0037] 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.

[0038] figure 1 For the flow chart of the wire path real-time calculation and inspection method according to the present invention, reference will be made below figure 1 , the real-time calculation and inspection method of the wire path of the present invention is described in detail.

[0039] First, in step 101, geometric data and constraint conditions for real-time inspection of super-long wires are received.

[0040] In this step, in order to start the real-time inspection of ultra-long wires, the engineer needs to specify the wire layer, contact layer, and maximum length limit value involved in the inspection. The contact layer is used to mark the wire endpoin...

Abstract

The invention discloses a conductor path real-time calculation and inspection method and engine. The method includes the steps: (1) receiving inputted geometric data and constraint conditions; (2) inspecting and outputting a conductor path breaking the constraint conditions by the traverse path real-time calculation and inspection engine; (3) back-annotating the conductor path breaking the constraint conditions to a layout design interface and assisting in correcting layout. According to the conductor path real-time calculation and inspection method and engine, when layout data are incomplete, results can be rapidly obtained only by inspecting the geometric data (including conductor polygonal shapes and conductor contact points) of a conductor material layer, real-time inspection requirements are met, and calculation amount is small.

Description

technical field [0001] The invention relates to the technical field of semiconductor integrated circuit design, in particular to a real-time inspection tool for ultra-long wires in layout design of semiconductor integrated circuits. Background technique [0002] During the layout design process of integrated circuits, multiple wire-related inspections are usually carried out to ensure correct manufacturability of integrated circuits and correct device functions, such as antenna inspection, wire resistance extraction and inspection, etc. The above related checks usually require complete layout data input and very complicated calculations to ensure the accuracy of the results, and the time and memory consumption required for the check process are relatively large. During the inspection process, a complete layout design is required in order to conduct wire-related inspections. Once the layout design is complete, once the inspection fails, it will be very troublesome to go back ...
