Working with Design Partitions Design Partitioning October 2019 27 Product Version 17.4-2019 © 1999-2019 All Rights Reserved. A: Cut lines should be used to quickly slice the design whereas shapes should be used when complex outlines are required. Q: Can partitions be created from copying rooms? A: Yes; and also from the board outline and constraint areas. Q: It is difficult to align partition boundaries to prevent a gap in between. What is the recommended use model when adding or editing a boundary? A: Use of a coarse grid when adding or editing is recommended. Q: Can a partition share a component? A: Yes. However, that component is tagged with an unowned status, meaning it cannot be moved once the design files are exported. Q: Can partition designer place components from the placement buffer? A: No. The master designer is responsible for allocating components prior to export. The use of Quickplace can expedite this process. Q: Can the master designer rename partition areas that default to partition_N? A: Yes. Q: Can the partition designer rename his partition area? A: No. Q: Can the master designer redirect .dpf file locations during export? A: No. By default the .dpfs are written to directories under the master designer's working directory. The directory name is the same as the partition name. Q: Can each partition designer rename their .dpf files? Perhaps as a result of a save as operation? A: Yes, but each team member must update the revised name in the workflow manager. It is best to keep the same design name throughout the team design process. The write command can be used to save the database to different names but keep the current version active. Q: Can another partition designer work on a .dpf assigned to a different user, without retracting or re-exporting the partition?
