The Design Verification Test (abbreviated DVT) report may be second most important tool as it reports all component stress under user defined situations. Reject, warning or pass will be commended on each component to ensure design quality.
Reject means that a fatal design error is present which must be corrected or fixed. Warning means there is a cut corner design, and no instant failure will occur. Pass means that the component is working safe.
Click on "DVT Report" on the left main menu to start DVT Report.
12.3 Introduction to Interface (standalone tool)Back to top
DVT Report can be used as a standalone tool. Users can add parts separately for this tool by clicking [+Part]. Users can also initialize a design before using DVT Report. Click the [Topology] button to start a design from Topology. For more details on starting a design from topology, please refer to Session 2.2.2--Start a Design from Topology. To start a design via another method, please refer to Session 2.2--Start a power supply design.
To enter the 4 Corners Test page, please click the [4 Corners Test] button.
To return to the previous page, click [Current Condition Test].
The 4 Corners Test page has six parts.
