DVM Tutorial

9.0 Tutorial Summary

This tutorial has covered the following concepts and tasks:

Configuring a working schematic to run successfully in DVM involves replacing the existing source(s) and load(s) with DVM source(s) and load(s) and then adding a DVM Control symbol to the schematic. This configuration process typically takes about 5 minutes at which point, the schematic can run any of the applicable built-in DVM test plans.
Selecting a subset of tests to run on a sync buck DC-DC converter and looking at each of the key elements of the resulting DVM test report illustrated how to add waveforms and scalar measurements to the report.
Two more built-in testplans, Efficiency and Line and Load Regulation, provided further examples of generating the DVM test reports.
The examples of customizing testplans to meet particular requirements included changing component values, adding curves to reports from the testplan, and generating tests that summarize results.
Additional customization examples demonstrated how to modify the built-in testplans, which included the following approaches:

Modifying the schematic to use variables
Using the Var() and GlobalVar() testplan functions to change component values
Using the Change() function to change component values directly without modifying the schematic.
Using the Change testplan entry to change the schematic configuration.

Using the Suppress, Promote, and Create testplan entries for general purpose post-processing included details about additional functions:

Using the Alias() function to create a copy of a scalar measurement with a new name.
Using the overview reporting functions, PromoteScalar() and PromoteGraph() to place measured scalar values and graphs on the overview report.
Using the NoSpecs(), NoScalars(), and NoCurve()functions to change the reported specification, scalar and curve data on a test-by-test basis.
Using the ArbitraryCurve() and ArbitraryBodePlot() functions to add curves to reports.
Using the ExtractCurve() createfunction to copy a curve generated in a previously run test to the current test, allowing direct, visual comparison of multiple curves.
Using the CreateXYScalarPlot() function to create new curves from the aggregated scalar measurements .

Using pre- and post- process scripts to create and report user-defined specifications and user- defined scalar values with the SimplisDVMAdvancedUtilCreateSpec and SimplisDVMAdvancedUtilCreateScalar functions.
Applying two applications of the Design Verification Module that measured, graphed and then saved efficiency, power loss, and control loop behavior across line and load variation.
