10 Life & MTBF Analysis Back to top
 1 YouTube



10.1 What is MTBF analysis? Back to top
MTBF analysis is a tool that allows users to add components and its corresponding stress one by one, then just at the press of a button, the life time and MTBF of the system will be known immediately. Users can treat it as a standalone tool to estimate the MTBF and life time of any product. If a power supply has initialized, all components and their corresponding stress in the power supply will be seamlessly transferred to the tool for simulation.

10.2 How to start Life & MTBF Analysis as a standalone tool Back to top
Click on "Life & MTBF" on the left main menu to start Life & MTBFAnalysis.


10.3 Introduction to Interface (standalone tool) Back to top
Life & MTBF Analysis can be used as a standalone tool but users must first add at least one part to BOM before using Life & MTBF Analysis.

Users can click the [+Part] button to add a part to BOM. Please refer to Session 14--Add Parts¡£

Additionally, users can first initialize a design rather than just add parts to BOM. Click [Topology] to start a design from choosing topology. Please refer to Session 2.2.2--Start a Design from Topology¡£
If users want to start a design by other methods please refer to Session 2.2--Start a power supply design¡£

After initializing a design, please refer to Session 6.5--Introduction to Interface (with topology) for more details about this tool with design.
