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

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/.

TNT and MMTL field solver programs are available on the web.  See:
