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.
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".
NG-SPICE is the program being developed as the replacement for Berkeley
SPICE. Using the Berkeley code as a starting point, the NG-SPICE team
is working on improving the build system, adding to the models, and
improving the analysis capability.
SPICE is a general-purpose circuit simulation program for nonlinear dc,
nonlinear transient, and linear ac analyses. Circuits may contain resistors,
capacitors, inductors, mutual inductors, independent voltage and current
sources, four types of dependent sources, lossless and lossy transmission
lines (two separate implementations), switches, uniform distributed RC
lines, and the five most common semiconductor devices: diodes, BJTs, JFETs,
MESFETs, and MOSFETs.
