Altium's Power Analyzer by Keysight technology brings powerful DC Power Integrity analysis into the board design environment. In your Altium design software, this is achieved by creating and configuring a Power Analyzer Keysight document, and then running an Altium Designer extension to extract all the power net analysis settings and the 3-dimensional copper structural data. This data is then passed to the Power Analyzer by Keysight DC PI analysis engine. 

Results of the physical simulation are displayed directly in the PCB editor as colored Heatmap overlays, where the designer can quickly identify the behavior of the board, capture images, and probe for more information.

The Power Analyzer by Keysight is under continuous development, this page outlines the changes made in each version. This page also includes information about supported versions of Altium Designer.

Power net configuration, the review of existing power analysis results, and the generation of a power analysis report can all be performed by anyone with a valid Altium Designer license. Performing a new Power Analysis requires a valid Power Analyzer by Keysight license. Learn more about licensing the Power Analyzer by Keysight

New in Power Analyzer by Keysight 1.0.6

Released: 16 March 2023 - Version 1.0.6 (build 129) 
Released with: Altium Designer 23.3.1 (build 30)
Works with: Altium Designer 22.10.1 (build 41) and later

X2-52837 It was not possible to probe a via on a heatmap. The probe value was the reading from the heatmap itself (Voltage Drop or Current Density) instead of the value for the pad's Via Current.
X2-52840 It is now possible to use several extended components in parallel.
X2-53330 In some cases, an Access Violation would be encountered after deleting a net from the *.pdnaK document.
X2-53743 An incorrect Via Current calculation was being used for Thru-Hole vias.

New in Power Analyzer by Keysight 1.0.5

Released: 15 February 2023 - Version 1.0.5 (build 121) 
Released with: Altium Designer 23.2.1 (build 34)
Works with: Altium Designer 22.10.1 (build 41) and later

X2-53490 Segments connected through microvias were not being simulated.

New in Power Analyzer by Keysight 1.0.4

Released: 17 January 2023 - Version 1.0.4 (build 110) 
Released with: Altium Designer 23.1.1 (build 15)
Works with: Altium Designer 22.10.1 (build 41) and later

X2-52247 For a specific design, simulation resulted in the Solver erroneously generating microsegments with unrealistically high consumption.
X2-52261 Values for Current Density and Via Current differed between the main document and the panel.
X2-52811 Added the ability to request a free 14-day trial to use the Power Analyzer by Keysight extension and its functionality.
X2-53093 For a specific design, an error would be encountered after setting load currents for the pins of a particular component and saving.
X2-53269 An exception would be encountered when showing analysis results on a PCB containing a duplicate layer ID.

New in Power Analyzer by Keysight 1.0.1

Released: 13 October 2022 – Version 1.0.1 (build 70)
Released with: Altium Designer 22.10.1 (build 41)

X2-50182 Configuration settings were not updating based on chosen Copper Type and fields were not editable upon choosing 'Custom'.
X2-50218 Specified load current values were not being processed correctly.
X2-51810 It is no longer a restriction that a source component must be connected to the selected power and ground nets at the same time.
X2-51813 In some cases, the Heatmap was not being presented for a layer in which violations were detected and polygons had been placed.
X2-51826 An error was encountered when trying to save the modified properties for a component in an extended net.
X2-51828 In some cases, the Voltage Drop for a power net was being interpreted incorrectly as an error.
X2-51829 The Use Logarithmic Scale option is now disabled by default, ensuring a linear scale is used for the Heatmap.
X2-52079 After running an analysis and closing/reopening the .pdnaK document, previously detected violations were no longer presented in the Power Analyzer by Keysight panel.
X2-52092 In the Configuration settings, 'Hole Size 1' and 'Hole Size 2' have been renamed to 'Minimum Via Diameter' and 'Maximum Via Diameter' respectively.
X2-52168 The caption for the command to launch the analyzer has been changed from 'Power Analyzer' to 'Power Analyzer by Keysight'.
X2-52236 After opening an older .pdna file, an error would be encountered the first time the 'Show on PCB' button was pressed.
