This is the Matlab frontend for the Wcalc transmission
line analysis/synthesis calculator. You will need a working
matlab installed on your system. In addition, currently
only a native (non-emulation) matlab is supported.
Wcalc is a transmission line analysis and synthesis tool. Several
structures including air core solenoid inductors, coaxial cable,
single and coupled microstrip, stripline, and metal-insulator-
semiconductor microstrip are included.
Wcalc can analyze the electrical parameters for a given physical
description of the structure or synthesize the required dimensions
to meet certain desired electrical characteristics.
Wcalc provides several different frontends for accessing the numeric
engine. Currently, there is a GTK based standalone graphical
user interface, a common gateway interface (CGI) for web access,
Scilab, Octave, and Matlab interfaces for maximum flexibility within
a scientific programming environment, and a standard input/output
(stdio) interface which allows a simple interface to other 3rd
party tools which can communicate via a pipe.
The different frontends are installed as different packages for
flexibility in deployment.
This is the library for wcalc which contains all of the numerical
backend routines and models.
Wcalc is a tool for the analysis and synthesis of transmission
line structures and related components. Wcalc provides the
ability to analyze the electrical parameters of a particular
structure based on the physical dimensions and material parameters.
The synthesis portion calculates the required physical parameters
to meet desired electrical specifications. Wcalc includes several
models and places an emphasis on accuracy. Several frontends
provide the user with several options for its use.
1) Simplify the way how an emacs version is picked when no emacs
is installed, but a user try to install an Emacs Lisp package.
Just pick up the version set as EMACS_TYPE than searching for
versions already installed etc. If the EMACS_TYPE version is
not supported by the Emacs Lisp Package, just fail. EMACS_TYPE
be default to GNU Emacs 21.
(In other words, users should set EMACS_TYPE as they want.
Otherwise GNU Emacs 21 is used.)
2) All Emacs Lisp Packages *must* prepend EMACS_PKGNAME_PREFIX to
a) the PKGNAME itself, and b) PKGNAME in its dependency lines.
EMACS_PKGNAME_PREFIX is expanded to "xemacs-" when XEmacs is
used. This keeps dependency graph of Emacs-Lisp-packages-
installed-for-XEmacs consistent.
3) Document EMACS_* variables as much as possible.
4) Provide more cookies for PLIST. Maybe utilized later.
Note that the 2) change doesn't affect the default, GNU Emacs 21
behaviour. So no version / revision bumps in this commit.
Major changes since the last snapshot:
- gsch2pcb updated to work with latest pcb
- pcb library directories default to something sane for gsch2pcb
- grenum utility for refdes renumbering added
- add a few new symbols
- added -p option to autoplace the windows. Useful for scripting.
- gattrib can now change attribute visibility
- improvements to the spice-sdb netlist backend
- added support for printing pictures in schematics to postscript
- added german translation
- fixed a segfault in the geda manager.
change is that it compiles with gcc3 now. Also works with the latest
wxGTK (2.6.1). This still has some issues reading gdsii files on alpha
but it seems ok on i386.
file's sole purpose was to provide a dependency on pkg-config and set
some environment variables. Instead, turn pkg-config into a "tool"
in the tools framework, where the pkg-config wrapper automatically
adds PKG_CONFIG_LIBDIR to the environment before invoking the real
pkg-config.
For all package Makefiles that included pkg-config/buildlink3.mk, remove
that inclusion and replace it with USE_TOOLS+=pkg-config.

Release Notes for PCB snapshot 20050609
========================================================================
- **** The GUI is now based on gtk2 instead of Xaw **** This represents
a fairly major change. You will now need gtk-2.4 or higher installed
along with any of its dependencies to build pcb. On linux
distributions, it is probably the case that you already have this.
For *BSD, Solaris, and others, you may want to use NetBSD's pkgsrc
to help install gtk2 and its dependencies.
- Flags are stored symbolically in the .pcb file. This is the start
of moving to support >8 layers. Please note that >8 layer support
is not yet available in this snapshot.
- Fixes for gcc-4
- As part of the switch to gtk2, the user customizable menu feature has
been temporarily broken. Hopefully this will be fixed by the next
snapshot. In addition, the loading of background images has also been
temporarily broken.
around at either build-time or at run-time is:
USE_TOOLS+= perl # build-time
USE_TOOLS+= perl:run # run-time
Also remove some places where perl5/buildlink3.mk was being included
by a package Makefile, but all that the package wanted was the Perl
executable.
run-time dependency (DEPENDS) on a tool is to append a ":run" modifier
to the tool name, e.g.,
USE_TOOLS+= perl:run
Tools without modifiers or with an explicit ":build" modifier will
cause build dependencies (BUILD_DEPENDS) on those tools to be added.
This makes the notation a bit more compact.
