The reliability calculation of existing circuits can be performed by customized reliability analysis software, or by manual table lookup based on industry standard manuals. However, the state, environment and other parameters of some devices will be specially set according to actual needs, which cannot be covered by reliability analysis software. In addition, for reliability calculations of different task states, the workload of manual table lookup increases exponentially, and once a table lookup error occurs, the evaluation data will have a large error, which will seriously affect the device selection and overall indicator coverage of the circuit design.

[0043] This embodiment discloses a reliability calculation method, such as Figure 1 As shown, the following steps are included:

[0044] Obtaining a component basic information table and a reliability input table, wherein the component basic information table includes a plurality of component basic information, and the reliability input table includes a plurality of task profiles of each component;

[0045] Selecting components to be calculated based on the component basic information table;

[0046] Determining a target task profile of the component to be calculated based on the reliability input table;

[0047] Obtaining reliability data of each target task profile of each component to be calculated based on the components to be calculated and the target task profile;

[0048] Allocating the reliability data of each target task profile of each component to be calculated to a calculation result table;

[0049] The reliability of each component to be calculated is obtained based on the calculation result table and a preset reliability distribution report.

[0050] In this embodiment, a reliability calculation method is proposed. First, a basic information table of components and a reliability input table are obtained. Then, based on the basic information table, components to be calculated are selected, and based on the components to be calculated and the reliability input table, a target task profile is selected. Then, based on the selected components to be calculated and the target task profile, the reliability data of each task profile is calculated using the reliability standard calculation formula. Finally, the reliability data of each task profile is allocated to the corresponding calculation result table, and the reliability of the components is obtained based on the comparison between the calculation result table and the preset reliability allocation report.

[0051] Specifically, the basic information table of components is an Excel table containing information of multiple components that need to calculate reliability. Different workbooks contain information of different components, including the name or code of the component and some parameters required for reliability analysis. The types of parameters vary depending on the component. For example, Table 1 shows the basic information table of a component, and its main information includes parameter information such as module, model, number of sets, package type, number of pins, number of gates, maturity stage, cycle rate, quality grade, and domestic and foreign environment.

[0052] Table 1 Basic information of components

[0053]

[0054]

[0055] Specifically, the reliability input table contains multiple mission profiles for each component. Mission profile refers to the working state of the component and its corresponding life process, different environmental coefficients and temperature coefficients, and even some special requirements, such as different environmental coefficients required for domestic and foreign components. Different workbooks of the same table record the different working states of the same component, as well as the corresponding mission profile of the working state and the influencing factors of other reliability analysis corresponding to the mission state. As shown in Table 2, it is the mission profile of a certain component under a certain working state. The table records its mission profile and other reliability analysis influencing factors corresponding to the mission profile. For example, in the road transportation of mission profile shipment, the corresponding factors affecting the reliability analysis include: domestic ground environment, foreign ground environment, ambient temperature, working state, time, domestic environmental calculated value, foreign environmental calculated value, etc.

[0056] Table 2 Reliability input table

[0057]

[0058] Specifically, during the calculation, the standard calculation formula is used to calculate each mission profile of each component to obtain the reliability data of all mission profiles, and then the reliability data is allocated to the calculation result table according to the name. The calculation result table records the reliability data of each mission profile of each component, and the calculation result table is shown in Table 3.

[0059] Table 3 Calculation results

[0060]

[0061]

[0062] Specifically, the reliability of the component to be calculated is obtained based on the weighted sum of the reliability data of all target task profiles of the component to be calculated. The reliability of the component is not simply the superposition of the reliability data of each task profile of the component, but it is necessary to look at the participation of each task profile in the component. Therefore, a weight is added to the reliability data of each task profile, and then the reliability data of each task profile after decentralization are added to obtain the reliability of the component.

[0063] Specifically, the reliability of components is allocated to the calculation report example table in order to facilitate comparison with the reliability allocation report to obtain the reliability of components. The calculation report example table contains the reliability of the entire components, as shown in Table 4.

[0066] Specifically, the reliability of components is obtained by comparing the calculation result table with the preset reliability allocation report. The reliability allocation report contains the reliability allocation results of components based on national standards and / or industry standards, which can be used to compare the calculated results to determine whether the components meet the use requirements in the task profile. The reliability allocation report is shown in Table 5.

[0067] Table 5 Reliability distribution report

[0068]

[0069]

[0070] Specifically, the reliability situation refers to whether the calculated reliability meets the usage requirements.

[0071] Specifically, through the reliability calculation method of the present invention, the components to be calculated can be flexibly selected, and the target task profiles in the components that need to participate in the reliability evaluation can also be flexibly selected. In addition, by comparing the reliability of each task profile with the results in the reliability distribution report, it is possible to understand whether a certain component of the component meets the use requirements and make targeted improvements.

[0072] In some embodiments, determining the target task profile of the component to be calculated based on the reliability input table includes:

[0073] In the case of selecting a mission profile from the reliability input table, using the mission profile to be calculated selected from the reliability input table as the target mission profile;

[0074] If no task profile is selected from the reliability input table, all task profiles of the components to be calculated are used as the target task profile.

[0075] In this embodiment, the reliability input table includes multiple target task profiles. In actual application scenarios, since each component corresponds to multiple working states, and the task profile corresponding to each working state is not the same, the multiple task profiles of the component will be recorded in the reliability input table. When calculating the reliability of a certain working state, the corresponding task profile may be several of them, so they need to be selected. If the task profile is not selected, all the task profiles corresponding to the components in the reliability input table will be calculated, which will result in a certain degree of waste of computing resources.

[0076] In some embodiments, the calculating and obtaining the reliability data of each target task profile of each component to be calculated based on the component to be calculated and the target task profile includes:

[0077] A component information feedback table is obtained based on the basic information table of the components to be calculated and a preset component reliability coefficient table, wherein the reliability coefficient table includes all the basic information of the components and their corresponding standard reliability coefficients, and the component information feedback table includes the basic information of the components to be calculated and the reliability coefficients obtained from the reliability coefficient table;

[0078] The reliability data of each target task profile of each component to be calculated is calculated based on the component information feedback table and the reliability input table.

[0079] In this embodiment, when calculating the reliability data, it is necessary to convert the component basic information table into a component information feedback table through a preset reliability coefficient table, and then call the component information feedback table and the reliability input table for calculation to obtain the reliability data of each target task profile.

[0080] Specifically, the reliability coefficient table is a standard table based on national standards or industry standards, which contains all components and their corresponding reliability coefficients. The reliability coefficients of the components to be calculated can be obtained through the reliability coefficient table, and then the component information feedback table containing the basic information of the components and their corresponding reliability coefficients is used in the reliability calculation. The calculation process is to import the relevant parameters into the standard calculation formula for calculation to obtain the reliability data. The reliability coefficient table is shown in Table 6, and the component information feedback table is shown in Table 7.

[0084]

[0085]

[0086] In some embodiments, the calculation result table includes a plurality of workbooks, each workbook including reliability data of a component;

[0087] The reliability data of a component includes the reliability data of all target mission profiles of the component.

[0088] In this embodiment, the calculation result table includes reliability data of multiple task profiles of multiple components, which need to be distinguished.

[0089] Specifically, each workbook contains reliability data of a component.

[0090] Specifically, each workbook contains reliability data for all target task profiles.

[0091] In some embodiments, the reliability condition includes:

[0092] If the reliability data of a certain task profile in the calculation report example table is greater than or equal to the corresponding reliability allocation result in the reliability allocation table, then the reliability of the task profile meets the use requirements;

[0093] If the reliability data of a certain task profile in the calculation report example table is less than the corresponding reliability allocation result in the reliability allocation table, the reliability of the task profile does not meet the use requirements.

[0094] In this embodiment, if the reliability data of a certain task profile in the calculation report example table is greater than or equal to the corresponding reliability allocation result in the reliability allocation table, then with respect to the task profile, its reliability meets the usage requirements; if the reliability data of a certain task profile in the calculation report example table is less than the corresponding reliability allocation result in the reliability allocation table, then the reliability of the task profile cannot meet the usage requirements, and the component properties corresponding to the task profile need to be optimized.

[0095] In some embodiments, in response to the reliability of a certain task profile in the calculation report example table not meeting the usage requirements, the corresponding properties of the components corresponding to the task profile may be optimized.

[0096] In this embodiment, in response to the reliability of a certain task profile in the calculation report example table not meeting the usage requirements, that is, the task profile is smaller when compared with the corresponding reliability allocation result in the reliability allocation table, the component properties corresponding to the task profile can be optimized in a targeted manner.

[0097] Specifically, for example, if it is found during reliability calculation that the reliability of the service life of a circuit board at a high temperature of 80℃ to 100℃ cannot meet the use requirements, then improvements will be made based on the factors affecting the service life of the circuit board at a high temperature of 80℃ to 100℃ corresponding to the task profile, such as improving the heat dissipation system, improving material quality, and improving welding technology.

[0098] In some embodiments, after optimizing the corresponding properties of the components corresponding to the task profile, a regression calculation is performed on the reliability of the components;

[0099] The regression calculation includes: recalculating the reliability of the component and the reliability data of the corresponding mission profile. If it still does not meet the use requirements, continue to optimize and calculate again until the reliability of the component meets the use requirements.

[0100] In this embodiment, the reliability of the optimized component is recalculated, and if the reliability of the component meets the use requirement, the optimization is stopped. If it still does not meet the use requirement, the optimization is continued, and then the regression calculation is performed again until the reliability of the component meets the use requirement.
