What
is GTviewer?
The process engineer who wants to measure special structures, or the design engineer who wants to check the final layout of his chip, need to display large GDSII/OASIS layout databases. Unfortunately, most layout editors are complex to run, require large memory and disk space for full-chip display. Leveraging unique technology for handling large layout databases,
XYALIS offers GTviewer, a fast and easy-to-use tool to display large
layout databases.
GTviewer is unique for its capability of displaying the
largest databases with low disk and memory requirements. GTviewer
directly works on compressed or gzipped databases without creating
temporary data on disk and with no impact on load time. In its low-memory
mode, GTviewer has no limit in the size of layout databases it can
load and display.
GTviewer is the only tool, which displays a top view or
a vertical cut view. This makes GTviewer the ideal tool to share
layout information between process and design engineers.
GTviewer has a user-friendly graphical interface, which
includes the most common navigation, measure, display and hierarchical
browsing features.
By providing the same user interface from PCs running Windows or
Linux to high-end workstations, GTviewer enables different design
teams with different platforms to efficiently share layout data
without error.
GTviewer also provides a powerful tool for documentation with its
integrated snapshot feature. With a single click, GTviewer creates
a screen snapshot in the most popular formats such as GIF, JPEG,
TIFF, PostScript, etc. Users can chose a black or white background
to maximize readability and printability.
GTviewer is the direct result of the expertise developed in GTsuite, the GDSII/OASIS manipulation tools created by XYALIS.
Main features
 Reads directly compressed or gzipped GDSII/OASIS files with minimum memory, disk usage and no temporary file creation or speed impact
Low-memory mode allows
to read huge data-base (no limit) with minimum memory requirements
Possibility to filter unused data during GDSII/OASIS input in order to furthermore reduce memory usage
Hierarchical browser
and navigation
Selective hierarchical
display allows to view only selected branches of the hierarchy
tree
"Where are you"
function gives all the data regarding layers and hierarchy
"GoTo" function
Easy -to-use ruler,
color and pattern selection, layer and data-type selection
Integrated snapshot
function to generate most popular formats (JPEG, TIFF, PostScript...)
Instantaneous redraw
of saved views.
Smart handling of corrupted GDSII/OASIS databases (multiple top cells, missing cells, ...)
Display a vertical
cut view of any part of the chip for device analysis
