A method and device for equal delay wiring

Abstract

The invention relates to an equal-time-delay wiring method. The equal-time-delay wiring method comprises at least the steps of recognizing geometric parameters of an area to be wired, dividing the area to be wired into serial geometric sub-segments based on the geometric parameters, producing initial wiring, calculating resistance and capacitance parameters of at least one geometric sub-segment and / or each network cable, calculating time delay parameters of each network cable based on the resistance and capacitance parameters of each geometric sub-segment of each network cable, and adaptively adjusting the geometric characteristics and / or positions of the corresponding geometric sub-segments and / or the network cables based on comparison between the time delay parameters and preset time delay parameters. On the premise that the process requirements for minimum wire width and minimum spacing are met, time delay values of the wired network cables can be small to the greatest extent and be approximately equal, response synchronization of devices (a logic gate, a storage unit and the like) driven by each network cable on an integrated circuit is achieved, and the performances of the integrated circuit are improved. Alternatively, display pixels corresponding to the network cables on a liquid crystal display panel are equal in brightness, the display performance of the panel is improved, and the integration performance is further improved.

Description

technical field

[0001] The invention relates to the field of electronic design automation, in particular to an equal delay wiring method and device. Background technique

[0002] With the continuous development of electronic technology, the wiring requirements for electronic design automation software for integrated circuits have been increased. The current mainstream wiring method is to first use automatic wiring and then fine-tune manual wiring. Automatic wiring has the characteristics of fast speed and high accuracy. Manual wiring adjusts the local unreasonable design of automatic wiring. Improve wiring efficiency and reduce the huge workload brought by a large number of integrated circuit components.

[0003] According to different application requirements, different wiring schemes need to be adopted. At present, the commonly used wiring schemes include equal resistance wiring, fixed value resistance wiring, etc. Among them, the wiring requirements for equal resistance ...
