Reports and Results
Once Allegro X AI has completed the component placement, the dashboard provides metrics related to:

Component Association Placement
Note: This metric is NOT displaying the percentage of components successfully placed on the PCB.
The component associations report provides an overview of all component associations, paired pins, and missing capacitors.
Allegro X AI provides a component association score for each completed design. The score quantifies the ratio of component associations successfully placed together plus decoupling capacitors paired with pins compared to the total number of power pins on ICs or connectors, plus component associations that you have defined.
A component associations score lower than 100% implies there are power pins without associated decoupling capacitors or associated components that were not successfully placed together.
To correctly identify decoupling capacitors, power net information must be provided either by specifying voltage properties in the constraint manager or through Allegro X AI.
Select the pie chart for the component association placement to view the Component Association Placement Report.
This report includes:
- Matched component associations
- Unmatched component associations
- Pins missing decoupling capacitors and the corresponding net
- Successfully placed decoupling capacitors with the corresponding component pin and net
- Number of insufficient decoupling capacitors and corresponding net
- Unmatched decoupling capacitors
Recommendations:
If the component association placement is poor, provide additional guidance to Allegro X AI by defining the component associations during Allegro X AI setup. Get the step-by-step instructions here.
DRC Results
The DRC Results reports how many design rule errors were created during component placement. Selecting the bar graph will display a detailed DRC Report.
The DRC report includes the number of design rule violations and information regarding the type of design rule being violated, location on the board, and more. Select the hyperlinked coordinates for DRC Marker Location to be brought to the location of the DRC error on the PCB.
Run Time
The run time displays the total time taken to complete component placement by Allegro X AI.
This metric will not display additional information when selected.
Additional Run Information
Timestamps with additional information about the Allegro X AI run are displayed. This includes the pre-checks and screenings performed as well as any errors or warnings encountered.
To improve Allegro X AI component placement results, errors and warnings can be addressed, the updated board can be uploaded to Allegro X AI, and component placement can be re-run.
