just a Clarification:
The removal of the negative planes is exclusively in XE or does it affect RE as well.
We have a lot of BS Classic design and I am not so familiar with the conversion process that would not allow us to revert back to BS Classic.
Using RE you can manage this, as long as negative planes stay in.
So if you remove negative planes, there is just the question of how well is the conversion from Classic to XE in this cases.
Many thanks for this clarification
The removal of negative planes only affects Board Station XE. There is a robust process for importing existing Board Station (classic and RE) designs into Board Station XE; this process includes the ability to map negative planes to positive planes. Customers using the BSXE flow have used this process repeatedly in production designs.
This change does not affect Board Station layout, nor Board Station RE.
