While working on very large scale Printed Circuit Board (PCB) files that contain a huge stack-up along with thousands of footprints and numerous shapes, the performance of the Allegro PCB Editor plays an important role in getting the board built in time. Below are example statistics for a large scale PCB:
Apart from upgrading the platform hardware to have more RAM, multi-core processor, or a better graphics adapter, there are several capabilities you can leverage in the Allegro PCB Editor that will help improve the overall performance.
Have you ever wondered how the Performance Advisor can improve the overall performance of Allegro PCB Editor when working on large board files?
Performance Advisor will analyze a design for possible performance issues and generate a report that provides solutions and recommendations to better manage your PCB design. It is an important check when working on large designs.The report generated would consist of objects responsible for performance degradation like constraints in the design that are not being used, constraint regions defined but with no values, or overlapping shapes.To access Performance Advisor, select Tools > Database Check from the Allegro PCB Editor. This launches the DBDoctor utility. Performance Advisor is a new utility added in DBDoctor GUI and is available from SPB 16.3 release.
In SPB 16.2, you will need to select Setup > User Preferences > Early_adopter and then select Performance Advisor to enable this function within DBDoctor.
If you are working with large scale designs and/or would like to improve the overall performance of the tool, the following Application Note should be helpful. This Application Note will cover other areas which, when tweaked appropriately, will improve the overall performance of the PCB Designs in Allegro PCB Editor.
