----------------
Release 20
----------------
* Fixes: model names starting with a number (1n4001) are now correctly parsed. The .global
command has been reinstated (it was previously disabled) and error messages now display
the corresponding line numberin the input deck.
* New Features: .measure command for transient, ac and dc analyses (still not complete, e.g.
DERIV is missing).
* Devices: Updated BISM4 model to revision 4.6.5. Added PWL (PieceWise Linear) functionality
for B (arbitrary generator) sources.
----------------
Release 19
----------------
Reveals an important work in compile scripts, many bug fixes in memory management, interface, and
work in device models.
* Compile scripts: tclspice and ADMS compiling fixes. Architecture compiling fixes for SunOS,
MS Visual Studio, MINGW, Cygwin.
* Memory management: fixed memory leaks, modifies memory management for MS Windos, integration of
espice bugfixes and enhancements, bug fixes in plots and cli interface.
* Rework of BSim models, integration of EPFL-EKV model V2.63, ADMS models mextram, hicum0, hicum2.
----------------
Release 18
----------------
Rework-18 is introduces several new features into ngspice. This is a major
release that comes after more than three years. During the silent years
ngspice developers worked in CVS to stabilize and introduce new features
into the simulator.
- Tclspice simulator library has been merged with ngspice. Now you can
compile ngapice or tclspice by asserting a configure switch. See README.tcl
- New options have been introduced: brief, listing, autostop and scale
- Support for .lib file has been introduced. This allows the use of
third party model libraries in ngspice.
- .measure statements: avg, integ, rms, max, min, delay, param
- .global statements t support for global nodes whose name is not expanded
when flattening the netlist.
- .func macros for inlining functions into netlists.
- Improved the numparam library to support fully parametrized netlists.
- BSIM model binning.
- new multi-input gate VCVS using XSPICE extensions.
Changes are:
Ng-spice-rework-17
============
This is a bug fix release. Previous release tarball did not included
an include file necessary for compiling numparam library.
Ng-spice-rework-16
============
Rework-16 comes out after almost one year of CVS development (from
15-fixedRC3). This release improves ngspice in three ways:
- Bug fixing: most of the bugs that affected rework-15 have been fixed,
thus ngspice is more stable, especially the xspice extension, the
subcircuit (X devices) handling and the numparam library.
- New features: netlist syntax has been expandend allowing for end-of-line
comments. A ".global" card has beed added to define global nodes, i.e.
nodes that are not expanded in subcircuits. It is possible to define TC
for resistors on the instance line. The editline library can be used
instead of readline (no more GPL license violation).
- Porting: ngspice now works (with xspice extension) on Windows using
MINGW/MSYS.
there have been many many bug fixes since the ng-spice-14. Notable
updates include bug fixes in the bjt pole/zero code, updates to the
bsim1,2,3 models, updated hsim model, updates the jfet model and
much code cleanup.
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:
lib/libfoo.a
lib/libfoo.la
lib/libfoo.so
lib/libfoo.so.0
lib/libfoo.so.0.1
one simply needs:
lib/libfoo.la
and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.
Also make LIBTOOLIZE_PLIST default to "yes".
Summary of changes:
- removal of USE_GTEXINFO
- addition of mk/texinfo.mk
- inclusion of this file in package Makefiles requiring it
- `install-info' substituted by `${INSTALL_INFO}' in PLISTs
- tuning of mk/bsd.pkg.mk:
removal of USE_GTEXINFO
INSTALL_INFO added to PLIST_SUBST
`${INSTALL_INFO}' replace `install-info' in target rules
print-PLIST target now generate `${INSTALL_INFO}' instead of `install-info'
- a couple of new patch files added for a handful of packages
- setting of the TEXINFO_OVERRIDE "switch" in packages Makefiles requiring it
- devel/cssc marked requiring texinfo 4.0
- a couple of packages Makefiles were tuned with respect of INFO_FILES and
makeinfo command usage
See -newly added by this commit- section 10.24 of Packages.txt for
further information.
A pkgsrc specific change is that it no longer conflicts with the
cad/spice package allowing both to be installed.
From the NEWS file:
This is a major release in terms of bug-fixes. Some enhancements
have been included: BSIM4 model and support for EKV model. The
source code for the latter must be obtained from EKV web site
(see DEVICE for more info). To enable EKV support you have
to obtain the code first and then use the configure switch
"--enable-ekv".
