Major News! Product sales have been discontinued.
All products are free Open-Source.
Release branch 4.3 (post-production) packages are now available,
Sorry about this: Package distribution will be discontinued
temporarily, for a couple of reasons. First, my day-job prevents the
attention needed to keep up with rapidly changing operating systems
such as Ubuntu, MS Windows, OS X, and others, resulting in broken
packages and frustration from you all (I'd be pissed too if I
downloaded something and it didn't work). Second, there is a major
update in progress to attampt to get around the decision by GTK
developers to go with cairo graphics exclusively in GTK-3, eliminating
the GDK drawing package that was "only a thin shell around the X
windows system" (which was perfect). Much work is needed to get
current with the GTK toolkit without loss of performance or
capability in rendering of large layouts.
Future distributions may rely on building from source, avaliable from
These products have had a nice run of 21 years in the commercial
marketplace. We've reached the point where this company does not have
the resources to take the software to the next level. Dr. Whiteley,
the founder of the company has decided to not "sell out", which would
almost assuredly mark the end of life of the software. Rather, by
releasing the software into the open-source domain, it is hoped that

continue evolving the programs, both directly and through coordination
with interested developers. The Apache license is compeletely free
and open, allowing commercial use and even resale. Packages will
continue to be available from this web site, but no more licensing or
To our customers: Thank You for your support over the years.
The new XicTools-4.3 consists of a git repository which
generates 8 packages: Xic, WRspice,
vl (a Verilog simulator, stand-alone and integrated into
WRspice), MRouter (a maze router for
Xic), adms (a Verilog-a to C++ converter
for creating WRspice plug-in device models),
FastCap (capacitance computation from geometry, for
Xic), FastHenry (inductance extraction,
for Xic), and mozy (stand-alone help/html
viewer and accessories). These programs work together and make use of
common resources, and the packages will supersede those previously
available from this web site. Package sets will be available here for
a number of supported platforms, including OS X, Windows, and various
Linux flavors. OpenAccess support is back, and Safe-Install is now
supported in Microsoft Windows packages.
