Version 3.02 08/1/08

This version supports Ciranova Python PCell (PyCell).
To setup the environment variables for Qckvu3 to support PyCell, users need to run the setup script:

[Ciranova PyCell Studio install path]/quickstart/bashrc

or

[Ciranova PyCell Studio install path]/quickstart/tcshrc

OpenAccess selection is now controlled using 1 or more OpenAccess library definition files (lib.defs). Libraries/cells/views specified in the selected lib.defs file(s) are available to be selected for opening.

The cell dialog now shows the library and view for each cell. Cells can be defined in different external libraries, and cells can have multiple layout views.
Cells in the selected library and view when opening are listed as a simple cell name. Cells in other libraries and views are listed as cell/lib/view. e.g.

parent
|__ child1/lib1/view4
|__ child2
|__ child3/lib2/view4

where parent and child2 are in the selected lib and view. lib1, lib2 and view4 are external libraries and different layout view.

Version 3.01 06/27/08

This version now supports both DM Systems OpenAccess libraries, FileSys and Turbo.

Previous version of Qckvu3 would not open OpenAccess libraries which the user does not have write permission to the OpenAccess library directory. This is now changed and write permission is only necessary for Turbo DM System OpenAccess libraries, not FileSys DM System libraries.

Previous version of Qckvu3 would not open OpenAccess libraries without a tech database or libraries which Qckvu3 cannot find the corresponding tech database.
This has been changed to allow opening OpenAccess libraries without a tech database and the default DBU per UU and unit are 1000 and UM respectively if no tech database is found.
Qckvu3 uses the tech database inside an OpenAccess library directory; if that doesn't exist, then it searches for tech libraries in the file lib.defs in the startup directory of Qckvu3. So user might want to start Qckvu3 from the directory where lib.defs resides.

Potential warnings about PCell will be shown to the user after the OpenAccess open process is done and user can choose to continue to view or cancel the open and close the OpenAccess.
