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 and 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.
With the relocation of the Power Analyzer documentation - to be an integral part of the Altium Designer documentation - release notes can now be found as part of the set of release notes for the applicable release of Altium Designer (see:
Public Release Notes for Altium Designer). Moving forward, any new features in relation to the Power Analyzer will be reflected on the
New in Altium Designer page, for the applicable release of Altium Designer.

Release Notes
| 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. |
| 52840 |
It is now possible to use several extended components in parallel. |
| 53330 |
In some cases, an Access Violation would be encountered after deleting a net from the *.pdnaK document. |
| 53743 |
An incorrect Via Current calculation was being used for Thru-Hole vias. |

Release Notes
| 53490 |
Segments connected through microvias were not being simulated. |

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