Editing in a Design Partition

In designer mode, by default in area-based design partitions, the area boundary for the selected design partition is highlighted and the region outside it is grayed out. This happens because the Only Select Inside Partition option is enabled by default in the Concurrent Layout assistant.

This helps in preventing users from selecting any objects outside their area partition. Additionally, any wire that is crossing the design partition is split by default at the boundary.

Editing in a layer-based design partition is similar to editing in an area-based design partition. The difference is that your edit scope is set to the range of layers included in that design partition. You can also perform tasks such as routing and interactive wire editing in these design partitions.

To create objects inside and outside the current design partition:

Create a rectangle inside the partition to start editing the design.
Add a shape outside the current design partition.
A glyph is displayed in canvas to warn you about possible edit conflicts. Additionally, a warning alert is added in the assistant to inform you about edits made outside the current design partition.
Clear edit conflicts:
1. Click sign off for the edits you want to retain or use filter to mark the changes you do not want to retain.
2. Click Remove Changes from Design Partition View to delete the filtered changes.
Click Save after you have completed editing the design.
The status of the design changes to Not submitted. You can continue editing the design after saving.
(Optional) Open Library Manager and check the size of the edited and saved design partition. You will notice a marginal increase in the size indicating that the design partition now comprises saved changes.
