The invention discloses a formulation method for a test specification of a chip product. The method comprises the steps of obtaining each to-be-tested sub-product contained in the target product; analyzing each test parameter included in each to-be-tested sub-product and determining an initial extreme value and offset extreme value corresponding to each test parameter; determining a test standardextreme value of each test parameter according to the corresponding initial extreme value and the corresponding offset extreme value; assigning each test standard extreme value to the corresponding to-be-tested sub-product to complete the formulation of the test specification of the target product. According to the formulation method, the test standard extreme values of the to-be-tested sub-products are collectively determined, and each test standard extreme value is assigned to the corresponding to-be-tested sub-product to complete the formulation of the test specification of the target product. One chip product corresponds to only one test specification, and the problems that it is needed to formulate a test specification for each sub-product, one chip product corresponds to multiple test specifications, and thus the data processing workload is large are avoided.
Description
[0001] This application claims the priority of the domestic application with the application number 201811171984.4 and the invention titled "A method and system for formulating a chip product testing specification", which was submitted to the China Patent Office on October 9, 2018, the entire contents of which are incorporated by reference in in this application. technical field [0002] The invention relates to the technical field of semiconductors, and in particular, to a method and system for formulating a test specification for a chip product. Background technique [0003] In the process of chip product testing, it is necessary to formulate test standards for the chips, and the test standards directly affect the yield rate and product performance indicators of product mass production. In the prior art, some chip products have multiple sub-products due to different packages and functions. The same test parameter is correlated across different sub-products. At this time,...
