Changes and Enhancements to the GDSII, OASIS, OA Layout Viewer are listed below:
This page summarizes the changes and fixes to each version of the Qckvu3.
Version 3.20 06/12/09Geometry Walker Plug In
This version supports the Geometry Walker feature plug in tool. It allows the user to import a text file with xy coordinates, and zoom in to each coordinate.Plug In
This version of Qckvu3 has support for plugins made by both Artwork or
the end users themselves. Artwork currently ships a few plugins:
In previous versions, when grabbing a rubber band and the y coordinate of the mouse goes beyond the drawing area, the y coordinate would overflow and the picture might become blank or no info data is reported. This has been fixed.
Version 3.18 03/01/09OASIS Optimization
This version improves by a factor of 5X to 10X the cell highlighting for files input as OASIS.
Version 3.15 02/04/09Fixed Check Box Bug in Selections Dialog
Fixed the scrolling bug where the checkbox for Delete/Move does not move with the scroll
Version 3.13 12/23/08OASIS text strings with new line character now supported
Previous versions of the software would halt (or crash) when reading an OASIS file that had a text string including a new line character. (Technically, this is forbidden by the OASIS spec). This version now reads such data correctly and also supports the CR character.Added BOX record type to GDSII input
previous versions were ignoring GDSII record type - BOX. This version now reads them and treats them the same as a boundary.
Version 3.11 11/21/08
This version includes some html based help manual incorporated into the help pull down menu and Help buttons in various dialogs. It launches the system browser for opening html files.Extract GDSII with Polygon Area Control
This version has a new Extract GDSII plugin that enables a user to select a polygonal shaped region to extract instead of a simple rectangular region. The user can also specify whether the program should clip any entities which cross the region boundary or extract the entire entity.
Version 3.10 11/21/08Bug Fix - Qckvu3 Crash when Tooltip Pops Up
Previous versions might crash under rare occasions when a tooltip popped up. This has been fixed.
Version 3.09 11/13/08 CA Wizard 1.05 11/13/08Qckvu3 Cell References Nesting Levels Setting
The nesting levels display control in the cell reference dialog in Qckvu3 now has a list box of nesting levels 0 to 20. User can select multiple levels to draw cell references boxes and labels.Qckvu3 Load File To Memory Setting Remembered
The "Load File To Memory" setting in the "Select GDSII" and "Select OASIS" dialogs is now remembered from session to session. Load On or Off status is displayed in the text area when opening a file.
Version 3.07 10/15/08Hang After Pick or Crashes with X Errors
Previous versions might hang or crash with X Windows error after picking an object when cell outline or label at level 0 (top cell) is turned on. This has been fixed.Plug In Info Mode
Plug in info mode now also works when walking around the vertices of a boundary or path.
Version 3.06 10/15/08Highlight Dialog
Added the array control/filter to draw array reference extents as outline, extents outline for the single references on the outer row and column, or extents outline for all single references of the array. By Default array processing = full.
Use can now click on the Pick button next to the cell name text box to pick cell name using mouse info to identify references. The name of the reference queried will then be shown in the cell name text box.
New highlight size control. Single pixel outline for highlighting was very difficult to discern in earlier versions. Bigger highlights are drawn in outline and the outline width in pixels is controllable. Smaller highlights are drawn in a minimum sized filled rectangles where the size in pixels is controllable. The highlight size slider controls both outline and fill sizes.
This slider also controls the size of the areas to be drawn after the highlights are added to a selection.
The selected cell's width and height are shown in the "Last Highlighted Cell" info panel. When the cell is highlighted, the highlights count is shown.
Default values for parents, nesting, array, window mode, highlight size are located in $HOME/.artwork/cawizard.Xdefaults
Added Single Reference Rule Control
When single reference rule is turned on, it automatically turns on pick mode. Use the mouse to info data and references will be auto highlighted. Click pick again to enter pick mode (if the mode has been changed to other zoom/info mode like zoom window.)Array reference in single reference rule is always drawn as array extents outline.Selection Set Dialog
Selection dialog now shows if a rule is a single reference rule or not. For single ref rule, there are no parents, nesting, array and window filter settings displayed; these fields remain empty.
In the selection dialog, the top cell information is taken out since all rules of all selections belong to the same top cell.
An export button is added to go to the next step of exporting selections to files.
Selections can be exported using the specified layer, datatype and cell name.
Exports are output to a directory which is selected when "Export..." is clicked. For now, it generates the specified GDSII output file, mappings.csv and config.csv (the 2 csv contain no meaningful information for this release).
Boolean operation is fully functional with grow, unionize and shrink. Only one gap parameter is available - i.e. Xgap = Ygap
Registration Marks is not yet functional.

More Qckvu Features Have Been Added To Qckvu3
Version 3.01 06/27/08FileSys and Turbo DM System OpenAccess Libraries
This version now supports both DM Systems OpenAccess libraries, FileSys and Turbo.Cannot Open OpenAccess Libraries (Write Permission)

This is now changed and write permission is only necessary for Turbo DM System OpenAccess libraries, not FileSys DM System libraries.Cannot Open OpenAccess Libraries
Previous version of Qckvu3 would not open OpenAccess libraries without
a tech database or libraries which Qckvu3 cannot find the corresponding
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.
This is the initial release for Qckvu3 (third generation Qckvu) that uses the new QISLIB with extensions to support Open Access databases.
