Qckvu for PROLITH v2.30 (9/16/2003)MAJOR Speed Up In Scanning and Loading
This version has speed up for files with lots of structures and/or
structure references, especially when many of the structure names are similar.
If the GDSII file has more than 5000 structures, older versions would ask if you want to show the child structure list. This has been suppressed and the program would automatically show as much as possible in a reasonable amount of time (10-60 seconds). A warning message would pop up if not all the structures are listed in the dialog. This also applies when expanding a structure tree in the dialog. A structure name can still be entered as the View Structure to the dialog even if it is not listed in the dialog. This only affects the listing of the structure name in the dialog, the data is not dropped from drawing or any other functionalities.NEW! - Export Structure Names and Hierarchy
In the structure dialog, when there are too many structures, some might
not be listed. To get a complete list of structure names or a complete
tree hierarchy for a specified structure name, use the Export function
to output it to a text file.
The FlexLM daemon, artwork, is included in the tools/flexlm directory for the UNIX/Linux versions.
Qckvu for PROLITH v2.17 (6/12/2003)MEBES Extraction Added
Qckvu can now extract MEBES data to PROLITH mask format. When both GDSII and MEBES files are simultaneously opened and their units differ, the unit shown on the lower right of the status bar is used (units of the first file opened). Such a case is not anticipated.Use Mouse to select clipping Window
The ability to specify the mask window using the mouse has been added. Click "Use Mouse To Specify Coordinates" to enter this mode; then window an area to get the coordinates; the mode will switch back to the original zoom mode.Set PROLITH Clip Coordinates Precision
The clip coordinates are now displayed in nanometers and respect the resolution of the source GDSII or MEBES file. For example, for a GDSII file whose units are um whose grid is set to 0.001 um, 5.123 um is now displayed as 5123.000 nm. Previously additional precision such as 5123.456 was displayed when in fact the extra precision was not real.GDSII Paths with Zero Width
GDSII paths with zero width will not output to the PROLITH mask file.FLEXLM Host ID and Disk Volume S/N Licensing
This version now supports these 2 new licensing schemes and does not require installation of the flexlm license manager.Help Contents
Older versions might not show some of the help topics. This has been fixed.
