Process flow for mfg. chip capable of pretesting efficiency, and testing method thereof

Abstract

A process for preparing chip whose efficacy can be tested in advance and its test method is characterized by that after a chip is designed, its functions are tested in a simulative environment, and after it passes through the test, a group of predefined test instructions are executed by it in a simulative environment while the time taken by it is recorded for comparing different designs with eachothers, so able to choosen optimal design.

Description

technical field [0001] The invention relates to a manufacturing process of a chip, in particular to a chip manufacturing process capable of pre-testing performance and a testing method thereof. Background technique [0002] In recent years, due to the rapid development of information-related industries and the trend of people seeking innovation and change, various electronic and information products have been continuously released, and existing products have been constantly refurbished or updated, which makes artificial dazzled. For manufacturers and merchants, the research and development of each new product will inevitably require various tests on samples of various specifications to verify whether the product design can operate correctly. Therefore, the quality management and testing of many products have become various A major issue for manufacturers. [0003] In the past, the main process of chip designers and manufacturers for a new chip product, from its design to p...

AI Technical Summary

Problems solved by technology

[0004] Generally, after the product design undergoes the simulation verification in step 103, the probability of design errors can be greatly reduced. Guarantee that the performance of the new chip design will be higher than that of the old chip design, but it must be assembled and tested after production to know how the chip will perform in terms of performance. Not only will it take a long time to test, but once its performance is not as expected , then this batch of raw materials for manufacturing and testing will be wasted in vain, which will virtually increase the production cost and weaken the competitiveness of the product.
