TNT-MMTL, the Multilayer Multiconductor Transmission Line 2-D and 2.5-D
|
|
electromagnetic modeling tool suite, generates transmission parameters
|
|
and SPICE models from descriptions of electronics interconnect
|
|
dimensions and materials properties.
|
|
|
|
MMTL programs and supporting libraries and documentation have been
|
|
under development at the Mayo Clinic since the mid-1980s. The programs
|
|
were developed under government sponsored electronics research
|
|
programs in the Special Purpose Processor Development Group
|
|
(SPPDG). They have been employed extensively at Mayo and distributed
|
|
to some government agencies and research collaborators. At the
|
|
beginning of 2004, we decided to release the TNT graphical front-end
|
|
and MMTL programs as free software under the GNU General Public
|
|
License (GPL). Technically, MMTL programs are in the class of 2-D and
|
|
2.5-D "field solvers", which convert dimensions and materials
|
|
properties into electronic design parameters. The MMTL suite consists
|
|
of several programs, including lossy, loss-free, quasi-static, and
|
|
full-wave simulators. Circuit parameters are computed by either the
|
|
method of moments (MOM) or finite element methods (FEM). Basic
|
|
per-unit-length parameters are generated by the simulator, and can be
|
|
converted into HSPICE W-element models. MMTL is similar in many ways
|
|
to commercial field solver products which typically cost thousands of
|
|
dollars.
