7.1i ISE - The Hierarchy Separator option does not get carried over when a 6.1i project is opened in 7.1i ISE


Keywords: migration, synthesis, property, conversion, underscore, forward slash

Urgency: Standard

General Description:
The synthesis option Hierarchy Separator does not get carried over from 6.xi to 7.1i during project migration.

- A project created in ISE 6.3i has the hierarchy separator option set to '/'.
- The project is opened in ISE 7.1i and converted to ISE 7.1i format.
- Instead of retaining the '/' value set in the original project, the Hierarchy Separator synthesis property is set to the default value '_'.


To work around this problem, migrate the project to 7.1i format and then reset the Hierarchy Separator property.

This problem has been fixed in the latest 7.1i Service Pack available at:
The first service pack containing the fix is 7.1i Service Pack 1.
