This branch contains reviewed code only that has been transferred to a CMake-based build process. For the full and patched original code, refer to the branch old_code in this git-repository.
TNT is the graphical front end supporting 2-D electromagnetic field solvers developed at the Mayo Special Purpose Processor Development Group (Mayo SPPDG). These field solvers can compute per-unit-length electrical characteristics from two dimensional descriptions of transmission lines.
Mayo SPPDG has been implementing and using a variety of electromagnetic modeling tools since the mid-1980s in support of its primary research mission: developing next generation electronics technology for high speed signal processor applications. The Mayo-developed applications have been known as the "MMTL" applications, for Multilayer Multiconductor Transmission Line analysis tools. For more information about Mayo SPPDG, visit http://www.mayo.edu/sppdg/
TNT is primarily a Tcl/Tk script application, and requires Tcl, Tk, Incr Tcl, IWidgets, and BWidget packages. These packages are freely available, and the source code can be downloaded from http://tcl.sourceforge.net/, http://incrtcl.sourceforge.net/, and http://tcllib.sourceforge.net/. Or you can download and install a free binary distribution of ActiveTcl which includes all these (and many other) packages from http://www.activestate.com/tcl/.

February 16, 2015 After some struggling with the original sources and trying to compile TNT and MMTL using the latest GNU compilers, I provide the patched sources via github. The original site at sourceforge seems to be discontinued since its original release. See https://github.com/fuesika/mmtl for the latest sources.
July 21, 2004 After much struggling, waiting, deciding, waiting some more, and eventually approving, TNT and MMTL are being released under the GNU General Public License. For the first time, these relatively straight-foward signal integrity tools are available to the public at large. See http://mmtl.sourceforge.net/ for the distribution.
