12 DVT Reports Back to top
 1 YouTube



12.1 What is DVT report? Back to top
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.

12.2 How to start the DVT Report Back to top
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.

After initializing a design, please refer to Session 12.5--Introduction to Interface (with design) for more details on how to use this tool.

  1. Top Bar ---------- Please refer to Session 9.3.7--Top bar
  2. Interface of Test Result ---------- Please refer to Session 12.5.3--Interface of Test Result
  3. 4 Corner Test ---------- Please refer to Session 12.5.2--4 Corners Test


12.4 How to start the DVT Report (with topology) Back to top
Click on "DVT Report" on the left main menu to start DVT Report.
