Ngspice is a mixed-level/mixed-signal circuit simulator. Its code is based on three open source software packages: Spice3f5, Cider1b1 and Xspice. This package contains the development files.
BSD-2-Clause
* Mon Jan 01 2024 Stefan Brüns <stefan.bruens@rwth-aachen.de>
- Update to version 42:
* KLU matrix solver has been added to the venerable Sparse 1.3
* Verilog-A device models (copiled by OpenVAF) now support
small signal noise simulation.
* Digital C coded circuit blocks may be read by the
code model d_process.
* Verilog (digital) circuits, compiled with Verilator,
may be read into ngspice by new code model d_cosim.
* For additional new features see the included NEWS file.
- Update to version 41:
* Analog node changes in VCD file output.
* Read Touchstone file for S parameter simulation.
* Completely renewed XSPICE d_osc code model.
* Updates to commands setscale, compose, eprvcd, iplot, and
listing.
* Option FREQ for E and G sources.
* New dot command .libsave.
* Wed Apr 05 2023 Stefan Brüns <stefan.bruens@rwth-aachen.de>
- Update to version 40:
* New features:
+ VBIC: Add optional parameters for determining the operation
region
+ VBIC: Add bvbe, bvbc, bvce, bvsub as SOA parameters
+ Add inertial delay to all basic digital code models, make it
available for U devices
+ VDMOS default parameters are now similar to IRF540 IRF9540
+ Add function atanh to .control section
+ Add a scale factor 'a' (atto, 1e-18)
* Bug fixes:
+ ngspice-40 is mostly a bug-fix release. In conjunction with
KiCad and shared ngspice, inappropriate user inputs have led
to crashing ngspice.
+ bugs no. 331, 619, 620, 624 have been fixed
+ 9 crash bugs (double delete, access NULL pointer etc)
removed which have occurred mostly due to incomplete or
faulty inputs.
+ Memory leaks removed
- Moved user manual (ngspice-doc) to separate source package.
* Tue Feb 14 2023 Stefan Brüns <stefan.bruens@rwth-aachen.de>
- Update to version 39:
* New features:
+ ngspice now offers simulation with Verilog-A models, using
its new OSDI interface and the OpenVAF model compiler. This
enhancement enables access to all modern compact models for
short channel MOS, FinFets, double gate transistors, SiGe
bipolars, and III-V HEMTs.
+ ngspice now supports nearly all features of digital PSPICE
compatible U devices (instances). Therefore we now may
simulate a wealth of digital devices. These are translated
into internal XSPICE event models, with very fast simulation.
+ For a list of additional new features please have a look at
the NEWS feature in the ngspice tarball.
* Patches: Many developer and user provided patches and bug
fixes have been applied.
* Fri Jan 27 2023 Stefan Brüns <stefan.bruens@rwth-aachen.de>
- Remove noarch from scripts package, spinit contains absolute
paths to binary codemodels.
- Update URL
* Sat Nov 05 2022 Stefan Brüns <stefan.bruens@rwth-aachen.de>
- Update to version 38:
* New features:
+ .probe command updated (current and power measurements).
+ Support of digital devices with U-instance models
(PSPICE compatible).
+ Automatic generation of A/D and D/A bridging interfaces, when
mixed signal simulation (combining analog and event-based
digital) is used.
+ Update to pow() function (LTSPICE compatible).
+ For a list of all new features please have a look at the
NEWS feature in the ngspice tarball.
* Patches: Many developer and user provided patches and bug
fixes have been applied.
* Sat Jun 25 2022 Stefan Brüns <stefan.bruens@rwth-aachen.de>
- Update to version 37:
* New features:
+ .probe command to measure currents, differential potentials
or device power dissipation
+ S-parameter simulation with command .sp
+ command 'esave' to save only relevant digital nodes
+ substantail speed-up of plotting under MS Windows
+ flags 'alle' and 'digitop' to the plot command
+ reduce XSPICE memory consumption dramatically
+ For a list of all new features please have a look at the
included NEWS file.
* Patches:
Many developer and user provided patches and bug fixes have
been applied. Other bugs and some memory leaks have been
removed as well.
- Remove obsolete ngspice-Use-gnuplot-terminal-auto-detection.patch
- Spec file cleanup
* Fri Feb 11 2022 Stefan Brüns <stefan.bruens@rwth-aachen.de>
- Update to version 36:
* New features:
+ .probe command to measure currents or differential potentials
+ x/y contour plots for 2d Cider simulation
+ new function integ (integration)
+ command 'wrnodev' to print matrix RHS as .ic = V(node_xx)
+ Transient operating point
+ more SOA (safe operating area) parameters on more devices
+ For a list of all new features please have a look at the
included NEWS file.
