About Comparing ECAD Assembly Designs
You can compare two iterations of an ECAD assembly and use the differences identified as proposals of change. The Creo View ECAD Validate application automatically opens in a separate window and displays the results of the comparison as transactions at runtime.
Select the node of a transaction in the Transaction Summary frame of Creo View ECAD Validate to view the corresponding object data in the Transactions List. Creo View ECAD Validate displays the following variations in data between the compare to and the current ECAD assembly. You can save the comparison results to an IDX file.
The object data differences.
The board outline and component changes in the context of the current assembly design.
The changed objects, such as the modified board outline and the added, deleted, moved, and modified components of the assembly design.
Component placement for both regular ECAD and mechanical components.
Change in position of solid and lightweight placement holes.
ECAD areas with or without cutouts.
If you do not assign unique reference designators to all patterned components of an ECAD assembly, the comparison only shows one of the patterned components. Additionally, you cannot add a component to the assembly design when a component with the same reference designator already exists in the assembly.
You can set the baseline *.eda file for the comparison in Creo Parametric or ECAD. In Creo Parametric, you can save an ECAD assembly as a baseline *.eda, *.idx, or native Creo Parametric*.asm file. The current assembly design is compared with its baseline *.eda or *.asm file.
You cannot compare panel assemblies.
Holes on boards are mapped to VIAs for EDA output.
