Parent Page: Simulation & Analysis Panels
The PDN Analyzer panel provides the user interface for the Altium PDN Analyzer powered by CST® (Computer Simulation Technology) Power Deliver Network (PDN) analysis tool, available as an Altium Extension application for Altium Designer. The highly configurable tool analyzes a board design's DC performance based on its electrical and physical properties, and thanks to its direct integration into the design software, displays real time network Power Integrity results in the PCB editor using both the 2D and 3D view modes.
► See the PDN Analyzer page for an overview of the DC simulation tool and the principles involved.
► See the PDN Analyzer Example Guide for information on using the tool.
When a PCB project design document is active, select Tools » PDN Analyzer from the main menu to open the PDN Analyzer panel.
► See Installation and Licensing information.
The dockable PDN Analyzer panel is best used in conjunction with the software's PCB Editor so the visual results of analysis run may be seen immediately in the design's copper layout. In its floating (undocked) mode the panel might be moved to a second monitor to maintain visual access to the PCB Editor, or the panel may be vertically/horizontally docked in the main design screen to share real estate with the PCB Editor.
For the latter case, the panel offers a compact interface mode that moves its main configuration pane to a separate tab option (Config). To switch to this mode, select the Compact Layout option from the panel's button drop down menu in the configuration pane/tab.
In Compact Layout mode the Configuration pane changes to tab access, which preserves screen space for the PCB Editor.
The Configuration pane (or Config tab) is devoted to simulation network control and presents an interactive graphic representation of the currently selected power network(s).
The section on the left of the Configuration pane/tab is used for simulation file management, and provides a hierarchical view of the simulation's loaded power networks. The complete network structure or individual power networks may be selected. The section's options include:
*.pdna
).1.xx
version of the PDN Analyzer (*.pidc_config
).*.pdna
)./PDNAnalyzer_Output
folder for the current simulation in a Windows file browser. Note that this includes a fully detailed event log file for the most recently run simulation (PDNAnalyzer.log
).*.pdna.settings
) and reset to their defaults.The main body of the Configuration pane provides an interactive graphic representation of the power network structure selected in the simulation's network tree (on the left). When the top level simulation name is selected, the graphic shows the overall connectivity of sub power networks – double click on a sub network graphic element to open that sub network. The interactive graphic also is used to construct a power network from the PCB design's net data and connectivity by using its right-click options, or by double-clicking on graphic elements.
Right click on the configuration graphic or one of its elements to access the following options:
The Device Properties dialog, used when adding or editing an existing device element (Load, Source, etc) provides settings to specify the device type, connectivity and parameters.
The dialogs's available settings options will depend on the function of the device element being placed or edited, but are generally as follows:
The Messages tab includes a sequential listing of simulation events for the most recently run PDN analysis, including any Violations that were encountered. In the situation of a failed simulation run, the list will include an event entry summarizing the issue. For more information on a simulation run, see the PDN_Analyser.log
file available via the configuration Explore option.
The PDN Analyzer interface's Visual tab provides a high level of control over how the power network analysis data is displayed in the PCB Editor. It allows you to specify what type of information is included in PCB layout rendering, the scaling of the results data, how and if points of interest are highlighted, and what information is exported. The rendered layout in the PCB Editor applies to the power network that is currently selected in the PDN Analyzer's Configuration network hierarchy.
Use the Visual tab's default settings as a starting point for setting up the PCB layout display. These are set to show the color-graduated voltage profile across all power rail nets in 2D mode – deselect the Overlay option to see the pure analysis results. Setting changes made in the Visual tab are immediately reflected in the PCB rendering.
The Visual tab options include:
/HTMLReport/ImagesCache
folder for later inclusion in a Report. See Analysis Report for more information.The Pins tab presents a list of all component pins in the design connected to configured power networks. Each component pin entry includes its number, connected net, and the associated Voltage and Current value results from the last simulation run. Click on a column header to order the list by that name, and click again to reverse the order.
Double click on an entry to cross probe to that pin in the PCB Editor. If the pin (pad) connection cannot be seen in the rendered view, ensure that the Layer and power Net it is connected to are enabled in the Configuration pane/tab.
The Pins tab listing ordered by Component reference and – hover the cursor over the image – ordered by pin Current.
The Vias tab presents a list of all PCB vias in the design connected to configured power networks. Each via entry includes its connected net, location co-ordinates, layer pair, and the associated end-to-end Voltage, Current and Current Density value results from the last simulation run. Click on a column header to order the list by that name, and click again to reverse the order.
Double click on an entry to cross probe to that via in the PCB Editor. If the via cannot be seen in the rendered view, ensure that Via
is checked in the Layer list (available in 3D view) and its connected power Net is enabled in the Configuration pane/tab.
The Vias tab listing ordered by Net connection and – hover the cursor over the image – ordered by Current Density.
A tab view is available for each available power network within the simulation configuration – the network tabs that are visible is determined by the power network selection in the Configuration pane/tab. Labeled as the network name, the power network tab provides a comprehensive listing of grouped simulation results and calculated data that applies to that power network. A network power consumption summary is also included.
The data groups in the listing apply to devices within the power network (sources, loads, and series elements), where a Performance Summary and a Pin Voltage/Current Details data entry is included for each device. Along with details about the device, the data groups present key voltage and current values, and in the case of the Performance summary, calculated safety margins that relate to the device limits as specified in the Device Properties dialog.
