NOTE: January 13, 2009
This repository has been updated after a too-long period of neglect. The programs have been updated to the latest versions, and modified where necessary to avoid problems with newer compilers (e.g. gcc-4.2.1) and supporting libraries. Obsolete stuff has been removed.

The programs with distribution files of the form xxx-setup.exe are distributions for Microsoft Windows, designed to run on any Win32 platform (98/NT/2000/XP/Vista). Simply execute the downloaded file to install.

Other files are in tar/gzip format intended for Unix/Linux platforms, or possibly Cygwin/Mingw under Windows. These are source code distributions that must be compiled, instructions are provided in the distributions. These should build without trouble, but may require some minor tweeking on some systems, or perhaps installation of supporting libraries.

Misc. Useful Stuff
A mini-blog about a few miscellaneous technical problems that have been solved.

The GTK+ widget library
This is a library of graphical user interface components for UNIX/Linux. The library is used with Whiteley Research products.

The Cygwin tools
The cygwin tools are a set of UNIX programs that do an excellent job of providing a UNIX-like environment under Microsoft Windows. The cygwin dynamic link library, the core of the project and used by all of the tools, provides many of the functions of the UNIX kernel. The set includes a complete program development environment similar to that found on a Linux system, which allows many UNIX/Linux applications to port to Windows directly. The disadvantage is legal: programs built in this environment contain copies of the cygwin library, which can not be distributed commercially without paying royalties.

This program is obsolete, and is no longer used at Whiteley Research Inc., as SpamAssassin frankly does a better job. It is provided in the hope that parts may be useful to application developers.

bsd-mail.patch (3.7 Kb)      HTTP Download      FTP Download
This is a patch for the common BSD mail program, which enables automatic saving of deleted messages to a folder. If you've ever lost messages due to deleting the wrong message by mistake, you know why this patch is needed. Requires source code to the mail program, for FreeBSD but should be applicable to others as well. See the patch file header for details.

At Whiteley Research, for security reasons the BSD mail program is used exclusively to read incoming email.

fastcap-2.0wr-011109.tar.gz (1.6 Mb)      HTTP Download      FTP Download
This is a modified version of the fastcap three dimensional capacitance extraction program, source code distribution for Unix/Linux and Windows (Mingw). More information can be found in README.FASTCAP.

fastcap-2.0wr-setup.exe (1.2 Mb)      HTTP Download      FTP Download
This is a modified version of the fastcap three dimensional capacitance extraction program, self-extracting binary for Windows. More information can be found in README.FASTCAP.

fasthenry-3.0wr-011109.tar.gz (1.4 Mb)      HTTP Download      FTP Download
This is a modified version of the fasthenry three dimensional inductance computation program which handles superconducting conductors. This is a source code distribution for Unix/Linux and Windows (mingw). More information can be found in README.FASTHENRY.

fasthenry-3.0wr-setup.exe (1.1 Mb)      HTTP Download      FTP Download
This is a modified version of the fasthenry three dimensional inductance computation program which handles superconducting conductors. This is a self-extracting binary distribution for Windows. More information can be found in README.FASTHENRY.

induct-011109.tar.gz (22 Kb)      HTTP Download      FTP Download
This is a 2-D Chang's algorithm evaluator for calculating the inductance of an array of superconductors, written by Jay Fleischman at Berkeley. This is the source code distribution, compiles under Unix/Linux or Windows (mingw).

ipat-2.3d-1.tar.gz (73 Kb)      HTTP Download      FTP Download
Ipat is a program for computing and plotting the interference patterns of two and three Josephson junction interferometers. It is designed for use under UNIX and the X-window system. This is a source code distribution that requires only the basic X libraries (no GTK).

ipat-2.8.tar.gz (60 Kb)      HTTP Download      FTP Download
This is a new, really nice version of ipat for Windows, and for UNIX or Linux using the GTK widget set for the user interface. It requires that gtk/glib be installed on the system (true for most Red Hat systems). See www.gtk.org to get this library. This version also builds using the mingw compiler (www.mingw.org) on Microsoft Windows, as a native application (no X-server or cygwin library needed). See README.IPAT for more info.

ipat-2.8-setup.exe (326 Kb)      HTTP Download      FTP Download
This is a self-extracting Windows binary release of ipat.

jjmodel.c (2 Kb)      HTTP Download      FTP Download
This is a simple program that generates Jspice3/WRspice models for Josephson junctions.

jsim-2.0d.tar.gz (65 Kb)      HTTP Download      FTP Download
This is the jsim Josephson junction circuit simulator developed at Berkeley. It is a small, fast, no frills simulator which can compile and run on just about any computer.

jspice3-2.5-011109.tar.gz (1.1 Mb)      HTTP Download      FTP Download
This is the Jspice3 circuit simulator, a version of SPICE with support for Josephson junctions and with enhanced graphics. This is the final release of the former commercial product, now officially open-source. The source code should compile on any Unix/Linux system with X libraries. It will not build on Microsoft Windows except perhaps under Cygwin with X libraries available.

kic-2.4b.tar.gz (348 Kb)      HTTP Download      FTP Download
Kic is a toy integrated circuit layout editor, which has actually been used to produce some fairly complex designs. It is GDSII and CIF compatible, supports arbitrary polygons, and is reasonably efficient. This is a source code distribution for any UNIX with X-windows, and Microsoft Windows (mingw or cygwin). DOS is no longer supported. See README.KIC for more information.

kic-2.4b-setup.exe (507 Kb)      HTTP Download      FTP Download
This is a self-extracting binary distribution of Kic for Microsoft Windows.

sline.c (11 Kb)      HTTP Download      FTP Download
This is a program for computing characteristics of superconducting microstripline.

vl-1.5.tar.gz (664 Kb)      HTTP Download      FTP Download
The vl program is a Verilog simulator. It is command-line driven (no graphics). Just about all of the standard Verilog functionality is supported (specify blocks and the PLI are not implemented yet). This is a source code distribution which should build on any unix-like system, including mingw. Lots of example files are provided.

vl-1.5-setup.exe (1.1 Mb)      HTTP Download      FTP Download
This is a Windows binary distribution of the vl Verilog simulator. The package provides the vl binary and a collection of example files.
