Differentiated simulation design method

Abstract

The invention provides a differentiated simulation design method. According to the method, an electric performance result obtained by performing signal simulation on a wiring rule provided by a chip manufacturer is taken as a reference standard; and when the simulation result of a differentiated wiring design of a user product is better than the simulation result of the wiring rule of the chip manufacturer, the risk degree of the design is low, namely the differentiated wiring design is suitable for a product patternmaking test. The method comprises the following specific steps of: simulating the wiring rule provided by the chip manufacturer; taking the simulation result as a standard for judging whether the differentiated design is reliable; performing a large amount of analogue simulation on differentiated products to make a wiring rule which has a better simulation result than the wiring rule provided by the chip manufacturer; and performing a subsequent design according to the wiring rule. By adopting the differentiated simulation design method, the design reliability of the products is improved greatly, and the differentiated design of the products is realized.

Description

Technical field [0001] The present invention relates to the development and design of differentiated electronic products with reference to the wiring rules of non-chip manufacturers, and specifically to a differentiated simulation design method. Background technique [0002] With the improvement of electronic product processing and manufacturing technology, product production costs have been greatly reduced, and the number of products has increased dramatically. However, the greatly increased number of single-function products has caused fierce market competition, and design and development companies have made relatively thin profits. Therefore, when developing and designing new-generation products, companies have carried out diversified functionally differentiated designs, such as reducing the number of motherboard stacks, replacing materials with lower costs, and adding additional I / O ports. For this differentiated design, for some reason, the wiring reference design provided ...

Problems solved by technology

For example, in order to reduce product costs, the company changed the rule-based 6-layer laminate into a 4-layer laminate without reference design, replaced the materials recommended by the reference design with lower-cost materials, and changed the design of the portless plug-in card to This card is used to increase the design of product I / O ports, etc., and the above ideas are often due to the fact that chip manufacturers do not design individual differentiated products. Therefore, the existence of this situation is not only a simplification of product design, but also a It also greatly limits the development imagination of designers
