File Extension Control Refined
Added GDS file extensions control. Users can specify what extension(s)
for the GDS files they usually use, so the GDS file selection dialog
box will show the files with those extensions accordingly, instead of
always fixed to *.gds.
Access this function via File | Preferences | File Extensions.
Log File Search
Added log window searching function.
Web Link to www.artwork.com
Users can go to the pull down menu Help/Artwork Web Page and link to
Artwork's home page.
Lserv4 Support
This version supports lserv4 and has been tested for Y2K Compatibility.
Windows 95 Long File Names
This version supports long file names.
Improved Structure Dialog
This version has a new structure dialog box which has the features for
showing the referencing tree, extents, etc. for each structure.
Demo Mode Output for RS274D
This version will activate demo output (film, RS274X and MDA output) so that
Gbrvu installed in the same directory as Asm600 can view these demo output. Previous
versions would not be able to launch GBBRVU in demo mode.
Fixed: Command Failed on Aperture Table
A "Command Failed" error message would pop up when clicking on the Aperture
button. This happened when selecting aperture file not locatedin the working directory. This has been fixed.
Fixed: Dropped GDSII Boxes...
Customer Don Mikalson IBM/NY has a file with 4 boxes around the drawing which
were dropped in Asm600 4.21. This has been fixed.
GBR2GDS v6.00 08-03-1998
This is a major rewrite of the old gbr2gds.
v6.00 08-03-1998
Handling of Foreign Aperture Files
The aperture import feature which never worked well has been replaced with
a link to our new APTGEN program; a stand alone aperture generator. This will
enable us to update APTGEN independently of GBR2GDS.
ArcSag Control
Added arcsag control in addition to arcres. Arcsag is in GDS output unit.
To just use arcres, dial in 0.0 for arcsag. Arcsag allows the user to set
the difference between the ideal curve and its approximation.
GDS Structure Names Checking
GDS structure names must all be unique. This version checks to make sure
they are all unique as entered by users.
Default GDS Output Structure Names
Default names are the gerber file names without the path. Any characters
other than alphanumeric, '_', '?' and '$' are changed to '_'.
Translation Engine
This version uses a brand new translation engine that supports advanced
RS274X features like step and repeat (SR), apertures macros (AM), etc.
AutoDetects Gerber Type: 274X, 274D, MDA
GBR2GDS now automatically detects if a Gerber file is in 274X, 274D or
MDA format. Users can also select the format of the files in the
file selection dialog box to bypass the auto detect mode.
File Extensions Customization
Added gerber file extensions control. Users can specify what extension(s)
each gerber format they usually use, so the gerber file selection dialog
box will show the files with those extensions accordingly, instead of
always fixed to *.gbr.
Access this function via File | Preferences | File Extensions.
Embedded Layers in a Gerber File
Embedded layers are no longer shown as @<1>:12345. They are now shown in
"gerber file name_L2", etc. Also, default GDS structure name for these embedded layers is now
"gerber file name_L2", instead of "@<1>:12345".
Log Search
Added log window searching function.
Fixed bug in Aperture Table
Older versions might crash when openning the aperture dialog box when POEX
dcodes are defined. This has been fixed.
GDS Output Resolution
This version has automatic output precision adjustment depending on the
gerber input precision. No more control over GDS output precision.
Draws Control
Path Extension control is changed to Draws Control
v6.00 UNIX Related Fixes 9/30/98
Nodelock License Fixed
Previous version did not work with nodelock license. This has
been fixed.
Updated the Gerber Viewer to Version 5.50
6.0 comes with the new Xgbrvu 5.50. Refer to Xgbrvu
revision history
New INSTALL Script and Node Locked Licensing
This version comes with a new INSTALL which support acs.key
for UNIX. The acs.key does not change the internal executable and
enables users to easily update their keycodes merely by changing
the contents of ACS.KEY.
Version 4.21 02-03-97
AutoDraw Function
AutoDraw scans the GDSII file for paths - it builds a table of each unique path
width and then automatically assigns a d-code corresponding to each width. This enables
the gds2gerber to use a single d-code to draw the path instead of filling it with
small apertures.
This function is extremely useful for processing GDSII files that represent circuit
boards, MCMs or IC packages with hundreds or thousands of paths.
Flash Circles Function
This function scans the GDSII file for boundaries that approximate circles. A boundary
with more than 20 sides and all angles equal is considered to be a circle approximation.
A table of unique diameters is built. Each unique diameter will be assigned a name and
that name can be assigned to a d-code. At translation time the boundary is "flashed" by
the appropriate D-code instead of filled.
The program accounts for any scale factor that has been entered into the configuration and
also takes care of any conversion from GDSII units to Gerber units.
This function is very useful for GDSII files that represent circuit boards or IC packages where
hundreds or thousands of round pads must be imaged.
To 'unflash' circles with a specific size, remove the dcode
from the aperture table. Circles are flashed without any compensation.
Default names are based on INCH for all english GDS units, and MM for all
metric GDS units. Only dcode of type round will be used as circle flashes.
Version 4.11 12/17/96
Supports structure names that have spaces in them.
Bug Fix: Reading certain GDSII files where a
structure was referenced in the file prior to defining
it in the file.
