Generating the Report

To generate a detailed report, click the button in the Power Analyzer by Keysight document (<ProjectName>.pdnaK). Alternatively, a report for any individual net can be generated by clicking the appropriate  button.

Detailed Net Report - Parameters

The Full Report lists all the power nets that have been analyzed; click a Net Name to open the detailed report for that net. The left side of the Net report lists:

• The name of the power net (and all sub-nets if it has been Extended), along with an overall Pass / Fail status. 
• Calculated Parameters: V_drop, I_density and I_{via_max}.
• If any of the calculated Parameters show a Warning (orange line) or Error (red line), suggestions on resolving these warnings/errors will be displayed below the Parameters.

Detailed Net Report - Results

The right side of the report includes collapsible sections for:

• Global Settings - physical properties of the board, such as the allowable current density, the type of copper, the working temperature, and so on. These are configured in the pdnaK document.
• Design Stackup - arrangement of the physical layers that make up the board, defined in the PCB Layer Stack Manager.
• Heatmap for Current Density - displays the distribution of current in that net throughout the copper for each layer in the board. The density of current is represented by color; the greater the current density, the hotter the color. 
• Heatmap for Voltage Drop - displays the range of voltages present on that net for each copper layer in the board. The higher the voltage, the hotter the color (or, the greater the voltage drop, the colder the color).
• System-Level Power Network Results - Tree of all devices configured in all of the power nets, highlighting the devices in the chosen power net.
• Network Details - Detailed report of the results of the analysis of that net, more about this in the next slide.

Detailed Net Report - Network Details

Use the Network Details section to quickly identify potential issues in the design. This section lists:

• Power Net Members - graphical representation of the Sources and Loads in the chosen power net, as defined in the pdnaK document. 
• Power Consumption - power consumed by the chosen power network.
• Least Margins - the margin is the difference between the allowed current and the calculated current, giving an indication of how much more current carrying capacity is available (the margin). The Least Margin identifies the location of the smallest margin (or greatest failure for a negative result). Use the Least Margin result to quickly identify the worst-case results for the Non-Via Current Density and the Via Current, expressed as an Absolute value (Allowed Current - Calculated Current), and also as a Percentage ((Allowed - Calculated) / Allowed * 100).  A zero or negative value indicates a Fail.
• List of Violations - the number of violations of each type that are present on the board.
• Failed Via Summary - a list of the via and thru-hole component pads whose Current or Current Density results return a Margin of zero or less. Results can be sorted by clicking a column heading; click a second time to sort in the other direction, hold Shift as you click to sub-sort additional columns.

Save the Report

To create an HTML report of the analyses, click the button. In the Save Report Settings dialog, configure the required power Networks and Data that you would like to include, then click button to save the report as a set of HTML files. The report is created in a date & time-stamped folder within the project folder, \PowerAnalyzerByKeysight_Output\HTMLReport\<ProjectName> [PDNA]_<Date>_<Time>. Locate and open the file Report.html to examine the report in your default browser.

Include Probe Results and Image Captures

Images captured via the button in the Power Analyzer by Keysight panel are automatically included at the end of the Network Details section of the HTML report, along with any images of Probe results saved using the the button.
